  1. Control your descent speed exactly and fine-tune it in 1 m/s increments. Found on the CKAN as Vertical Velocity Controller This mod assumed you will use the Z key to control it. However, as this conflicts with the Set Throttle to Max command the mod is bound to no key upon installation You can use the on-screen buttons to control the mod but the following instructions on how to use this mod assume you have unbound the Set Throttle to Max command from the Z key and bound the Z key to this mod. The closest available alternate key for the Set Throttle to Max command is the Tilde(~) key, all other keys on the left side of the keyboard are bound to something else already. Latest Update: Version 1.32: KSP 1.3 Compatibility update. Localization is not supported in this version, English is still hard-coded. Localization will be added when this mod moves to the new GUI. KNOWN ISSUE: Due to this mod still using the old GUI system, some computers freeze for several seconds the first time a window using the old GUI is made visible in the game. This should only happen once per game session the first time an old style window (from any mod) is shown on screen by KSP. Moving to the new GUI in the next version (barring any bugfix releases that come first) will resolve this. Now, for feedback when your vessel is landed, the "Altitude:" text will change to a green "LANDED" text to indicate you are touched down even though the altitude is still reading a few meters of altitude. Full changlog here. Download: The mod is available on GitHub here. (Version 1.32) Source code on GitHub Module Manager is required for this mod to work. Download it here. This mod's icon will display in the stock toolbar if Blizzy's toolbar is not installed. Blizzy's Toolbar can be found here: blizzy's Toolbar Add-on License: Released under GPL 3 license. What this mod does: -Set a vertical velocity setpoint that will automatically maintained via downwards pointing engines. -The mod compensates for vessel angle off vertical so you can move sideways while keeping vertical speed the same. -Weight changes, such as burned fuel, are also automatically accounted for. -Aerodynamic lift from wings is accounted for. (Tail fins on a rocket will generate lift even when they point straight up.) -The setpoint can be set to the current vertical velocity or to 0 to maintain altitude. -The velocity setpoint can then be modified in 1m/s increments. (Configurable increment.) -Accounts for the presence of SRBs to make this usable during launch to avoid hitting terminal velocity. -Should be compatible with all mods, please let me know of any conflicts -Supports Davon Throttle Control mod to only control engines on Throttle 0 Details What his mod does not do: -Control vessels that generate lift solely with wings. If there are no downwards pointing engines, this mod can not do anything. Combination VTOL's work great though, especially in the horizontal transition as you pick up speed and the wings generate more and more lift. Want to control your horizontal velocity? Horizontal Landing Aid Quickstart: Show interface: Click the VEL button on the Toolbar (if installed) or hit Z to display the mod interface. Note that pressing Z will engage velocity control mode and maintain your current vertical velocity. Click the VEL button again to hide or click the bottom mode button when it is Control Off to hide the mod interface. Show settings: Click the Wrench Icon in the lower right. Vessel Tilt Compensation: This mod will compensate for the angle of your vessel and will maintain the vertical speed as directed. This is limited by your available engine power however, if you tilt far enough over that 100% engine power can not keep you up, the engine will lock at 100% and you will have to adjust your vessel's angle. (Or disable the mod until you recover.) Aerodynamic Lift Compensation: Because of the approximate nature of how KSP calculates lift, rocket tail fins generate lift even when pointed straight up. The mod compensates for this to keep your vertical speed at the setpoint. (In tests, the stock Kerbal 2 rocket was generating an acceleration of 0.5m/s^2 upwards with a horizontal speed as low as 25m/s from the 3 control winglets.) Keyboard bindings: By default this mod uses the Z key, although this can be changed if desired. Otherwise it uses the keys that are bound to throttle control, by default these are Left-Shift, Left-Control and X. This guide will refer to the keys by these defaults, but if you have changed which keys control the throttle, use those keys instead. These bindings correspond to the 4 top buttons (Off, Zero Vel, +1, -1). The Height Control and Operation Mode button have no keyboard binding and must be clicked. Note that you can rebind this key to any key on the keyboard, a mouse button, a joystick button, or a controller button. However, there is no conflict check, if you bind the key to something already in use, both functions will execute when the button is pressed. Velocity Step Size: On the settings screen, you can change the size of the velocity step from the default 1m/s. Note that due to how KSP handles text boxes, you can not enter 0.5 directly, rather you must enter the 5, then cursor back and enter the decimal point. This is due to the fact that KSP 'auto-corrects' the 0. to 0 and deletes the decimal point if no number is after it. Emergency stop: At any time, press any throttle key while Z is not held down will turn this mod off and return to KSP's default control scheme. Note that during orbital descent ("Free Pitch"), pressing a throttle key will behave as normal, but will not disable the mod. To disable the mod during orbital descent requires a double tap of the Z key. The first tap turns off Height Control and goes to Velocity Control, the second tap disable the mod. Altitude: Be aware that the altitude reported is to the vessel's center of mass and so will report an altitude of a few meters even when you are landed. For confirmation you have landed, the "Altitude" text will change to green "LANDED" text when you are touching the ground. Soft landing (Velocity Control): Press Z to maintain your current descent velocity, once near the ground hit Z-X to start hovering. Leave enough height to slow down, this mod can only slow you as fast as your activated engines will allow. Tilt your vessel to slide horizontally with your desired landing spot. Press Z-Ctrl to start descending, each press of Ctrl will increase the descent speed by 1m/s. As you approach touch down, press Z-Shift to decrease your descent speed (1m/s per press) and touchdown at a nice soft 1m/s or 2m/s. Once landed hit X (without holding down Z) to cut engines and disable this mod. Soft takeoff (Velocity Control): Press Z-X to enable the mod and set the desired velocity to zero. Press Z-Shift to increased your ascent rate by 1m/s per press. Press Z-X to set your velocity setpoint to zero to enter a hover, or press Z-Ctrl to reduce your ascent speed by 1m/s per press. Liftoff speed control: Takeoff as normal, once you reach your desired vertical speed hit Z and that speed will be maintained. Once clear of the lower atmosphere, hit any throttle key (while Z is not pressed) to disable the mod and continue your ascent as normal. Note that this mod controls vertical speed only. As you tip over your total speed will increase as your horizontal speed becomes a larger part of your total velocity. Height Control: First, the desired height to fly to must be entered. Click the 'Fly To' text box and enter your desired altitude. Only numbers and special keys (arrow keys, backspace, delete, etc.) are valid. Be aware that while the text box has focus, commands are not issued to KSP. However, pressing any non-number key such as W will cause the text box to lose focus and return control to KSP. It may take two key presses however, one to return focus and a second to issue the command. Once the desired altitude is entered, click the Auto Height button to engage and your vessel will fly the desired altitude. The mod will compensate for vessel tilt (up to about 30°) so you can control your horizontal speed by tilting your vessel. Pressing a throttle key will disable height control and return you to the default KSP controls. Pressing Z will enter Velocity Control mode with the Velocity Setpoint your current vertical speed. Height control can be enabled anytime the gray 'Auto Height' button is present. See warning messages below if you do not have this button. Descent from orbit (Height Control): When descending from orbit (or from a sufficient height), there is a special "Free Pitch" mode available. To use, enter the altitude you desire to stop and hover at in the 'Fly To' text box. The auto height button should say "Auto Height (Free)". Click this and the auto height button should change to "Free Pitch". This effectively arms the Height Control mode to take control of the throttle once you are low enough, but does nothing at this height. Continue to control your ship via the normal KSP keybindings to de-orbit. Note that pressing a throttle key does not disable the mod while in this mode. When you are 20 seconds away from the height where the Height Control mode needs to take over to hover at the desired altitude, the "Free Pitch" will change to "Thrust Warning", you then have those 20 seconds to return your vessel to pointing straight up so that the Height Control can take control of the throttle to bring you to a stop at your desired altitude. Height Control Button Warnings: This button can display several different things: TWR LOW: This means that 80% throttle, your vessel currently can not accelerate upwards. More engine power is required for Height Control to work. Velocity Control mode can still be engaged. TWR HIGH: This means that 1% throttle, your vessel currently can not accelerate downwards. This is almost exclusively caused by the presence of Solid Rocket Boosters. Height Control can not engage until the SRBs are expended. Velocity Control mode can still be engaged. Note that if either TWR HIGH or LOW become true when Height Control mode has been engaged, control will revert to Velocity Control with a setpoint of 0 so the craft will attempt to hover until you can correct the situation. Auto Height (gray text): Height Control is not currently engaged (although Velocity Control may). Click to activate Height Control mode. Auto Height (Free) (gray text): Your altitude is high enough that entering Height Control mode will be in the orbital descent "Free Pitch" mode, leaving you with throttle control Auto Height (Now) (gray text): Your altitude is such that Height Control will take control of the throttle as soon as you enter it. Auto Height (Thrust) (gray text): Your altitude is such that Height Control will take control of the throttle as soon as you enter it, but you are in the 20 second buffer zone between Free Pitch mode and Normal Height Control mode. In Auto: Height Control mode has control of the ship and everything is normal. You may pitch the vessel up to 35° off vertical for horizontal speed control and the Height Control mode will automatically adjust your vertical velocity to compensate. OVER PITCH: (Over Pitch in yellow text.) This is a warning condition that the vessel is greater the 35° off vertical and Height Control may not be able to compensate for that pitch angle. Height Control will still attempt to however and if you return to less then 35° off vertical, Height Control will be able to recover and return your vessel to the desired altitude. Free Pitch: This is a special condition that is only present during long descents, usually from orbit. When this mode is displayed you have full control of your vessel, including the throttle. During this time, pressing a throttle key controls the throttle and does not disable this mod. THRUST WARNING: (Thrust Warning in yellow text.) This is a warning condition that the vessel is about to thrust vertically to hold at the desired altitude. When this is displayed, you are leavingFree Pitch mode and you have 20 seconds to return to less then 35° off vertical, otherwise you may overshoot your desired altitude. Skycrane mode As of version 1.18, the compensation for adding and removing loads from a skycrane is now handled silently in the background by the mod. When you attach or detach a load from a skycrane, the mod should compensate for the weight different in a very short time (half a second or less) and you can fly as normal from there. Mod Use (Refer to screen shot above): Current Vertical Velocity: Shows you current vertical velocity regardless of whether this mod is engaged or not. Positive numbers is upwards velocity, negative numbers downward velocity. Velocity Setpoint: Has 3 modes. "---.--" is displayed when this mod is not engaged. "123.12" A number displays when the mod is engaged in Velocity Control mode and shows what the current target velocity is. "Auto" displays when Height Control mode is engaged. Disable Velocity Control: Clicking this button disables this mod (both Vertical Velocity and Height Control modes). This is the same as pressing a throttle key (Shift/L-Ctrl/X) with Z not held down. Set Vertical Velocity to Zero: Clicking this button enables this mod in Velocity Control mode and sets the Velocity Setpoint to 0 (zero). This is the same as pressing Z-X on the keyboard. Increase/Decrease Vertical Velocity by 1m/s: Clicking these buttons will increase or decrease the Velocity Setpoint by 1m/s when in Velocity Control mode. If the mod is not in Velocity Control mode (so not engaged or in Height Control mode), the mod will engage Velocity Control mode and use the ship's current velocity as the Velocity Setpoint. This is the same and pressing Z-Shift or Z-LCtrl on the keyboard. Target and Current Altitude: The current altitude of your ship and the desired target altitude above terrain (not sea level as displayed at the top of the screen) for Height Control Mode. Height Control Button: The button for Height control mode. Operating Mode: Shows you which mode the mod is currently in. "Height Control Mode", "Velocity Control Mode" or not engaged ("Control Off"). Click this button to go from Height Control to Velocity Control, and then click again to go from Velocity Control to Control Off. Direction: Set which direction is up. Click 'Direction' to see the current setting and the Up Down Forward Back Left Right buttons to set the up direction that way relative to the root part's local axis (which can be different then the world axis.) A red arrow will appear showing which direction is now up. This setting saves on a per vessel basis. Known limitations: -Jet Engine spooling is not fully accounted for and the craft will bounce before settling if jet engines are the primary source of lift. (No fix possible) -Does not account for RCS -Only practical near planets surface
  2. Kill your horizontal velocity before landing, or hover over a selected point on the ground. Found on the CKAN as Horizontal Landing Aid Latest Update: KSP 1.3: Current version works without requiring any updates. This mod requires a working SAS to function. Make sure you have a pilot kerbal or a high-enough level probe core along for this mod to function. Download Download release from GitHub here. Merge the GameData directory in the .zip file with your KSP-Install\GameData directory. Source code also on GitHub. License: GPL3 This mod supports Blizzy's Toolbar mod and will display it's button there if installed. If Blizzy's toolbar is not installed, the button will display on the stock toolbar. Modulemanager is a required dependency. Want to control your vertical velocity? Automated Vertical Velocity Control Button when showing Blue. Button also shows Red and Gray (or transparent to show window color technically). The button has 3 colors: Gray: Mod is off and will not activate. Left-Click to go to Zero Mode (Blue) Right-Click to go to Location Hover mode (Red) Blue: Mod is activated and will cancel your horizontal velocity as fast as it can Left-Click to turn mod off (Gray) Right-Click to go to Location Hover mode (Red) Red: Mod is on and in Location Hover mode. Left-Click to turn mod off (Gray) Right-Click to go to Zero mode (Blue) Yellow Border: When the mod is actively controlling the vessel, the icon will have a yellow border around it. Engage Height: Regardless of which mode the mod is in, it will not activate unless you vessel is within 1000 meters of the ground. As the mod zero's out your velocity relative to a point on the surface, zeroing out too high wastes fuel as your vessels' sideways velocity is higher the then sideways velocity of the ground under it. This limit is adjustable by right-clicking the LA button and entering the height you wish to engage at. SAS: SAS must be enabled to use the mod. In fact, the mod works by controlling the SAS direction. This means that while this mod is enabled, the vessel control keys (WASDQE) are not effective as the mod will override their inputs as soon as you release them. RCS: While vessel tip is the primary method of control, if the RCS system is on and there are RCS blocks on the vessel, the mod will use the RCS to help out. Particularly on lower gravity worlds, this speeds up the rate at which the vessel responds as even the maximum default tip of 20° only provides a sideways acceleration of about 15% the force of gravity currently pulling downwards on the vessel. Note that the RCS system does not affect if the mod is engaged or not, it is optional. (Unlike the SAS system which must be engaged for the mod to control the vessel.) To Use: Zero Mode (Blue): In this mode, the mod will simply cancel your horizontal velocity. Once canceled it will keep you hovering over whichever point on the ground you are over. This is intended for landing a skycrane with a horizontal velocity of zero so there is no chance of tipping over from having too much sideways momentum. Location Hover (Red): When you enter this mod, a red arrow will attach itself to your mouse. Left-click on the ground to set a target location, the red arrow will now attach itself to this point. This mod will then take your vessel and attempt to hover over the red arrow. Note that it is likely your vessel will overshoot on its first approach I am still tweaking the move-to-point math to get it exactly as I want. I will further tweak this based on people's reports. Note: For the purposes of location, the part you have selected as the "Control From Here" part is what the mod will keep above the target. If you have a docking port on the side of your vessel, you can "Control from Here" and rotate your vessel around that point for a precision landing. Note2: Right clicking to enter Location Hover mode also opens the settings screen. Settings: (Saved on a per vessel basis) Engage Height: The mod will only take control at or below this height above terrain. Note that the default altimeter at the top of the screen displays height above sea level. Defaults to 500m. Max Tip: How far off vertical the mod will allow the vessel to go. Defaults to 20° Larger vessels with a slower torque response may wish to lower this. Speed%: This is the speed with, or the aggressiveness, the mod uses. A lower number will result in a slower approach to target and a slower max speed while traveling. In percent, defaults to 100%. Really large vessels, or odd configurations (such as engines above the center of mass) may benefit from changing this number but player preference will vary. Use RCS only?: You can have this mod use the RCS only to move your vessel if you set the max tip to 0 and engage the RCS thrusters. Note that this will be highly vessel dependent, it can be painfully slow on larger vessels as effective RCS thrust is so low.
