At this moment i'll use temporary solution - simply force to sleep all Rigidbodys:

Rigidbody[] rbs = (Rigidbody[])FindObjectsOfType(typeof(Rigidbody));

and OnFixedUpdate() :

foreach (var rb in rbs)
              {
                  rb.Sleep();
              }

This completely disables physics and collisions, so it may be helpful to anyone who looking for this.

I just not sure if this is a best way...

----------

Finally slove this problem, so how to "Determine collision at point":

CelestialBody.pqsController.GetSurfaceHeight(Vector3d radialVector) gives us a terrain altitude at some point.

According to mechJeb & HyperEdit:

Vector3d radialVector =  ( QuaternionD.AngleAxis(Longitude, Vector3d.down) *
                    QuaternionD.AngleAxis(Latitude, Vector3d.forward) * Vector3d.right),

where:

double Longitude = vessel.mainBody.GetLongitude(point);
double Latitude = vessel.mainBody.GetLatitude(point);

and:

Vector3d point - some coords in world coord system.

Finally:

Vector3d point;  //coords (vessel or anything else)
            double Longitude = vessel.mainBody.GetLongitude(point);
            double Latitude = vessel.mainBody.GetLatitude(point);

            double srfHeight = vessel.mainBody.pqsController.GetSurfaceHeight(
                    QuaternionD.AngleAxis(Longitude, Vector3d.down) *
                    QuaternionD.AngleAxis(Latitude, Vector3d.forward) * Vector3d.right) -
                          vessel.mainBody.pqsController.radius; //surface height, shows negative values if under sea level

            double alt = (Vector3d.Distance(vessel.mainBody.transform.position, point) - vessel.mainBody.Radius);  //altitude, shows negative values if under sea level too

and if

srfHeight > alt

anything located on "point" will explode.

Just note that pqsController of Sun = null!

You could solve this by adding "fudge physics" with something along the lines of "gravitational effects cause warp to slow down or malfunction" so that once you have x ammount of gravity, warp stops. Much like how timewarp currently works.

Thank you, but if i understood you right this solution will be equals to "stop warp if vessel below constant altitude at sea level". I can just increase "sphere" where warp stops like: vessel.mainBody.Radius + 10000, so warp will brake under 10km (altitude at sea level).

And are you shure that time warp works simmilar to your answer?

I see in documentation that every CelestialBodiy object has their own set of altitude limits for maximum time warp multiper.

This is not actually i'm looking for.

For example - i wanna warp from KSC's runway to the Mun which is behind those mountains on the west side, so minimum warp altitude at KSC will be ~100 meters and in mountains it should be several thousands. I can't set constant "x" for all planet.

December 27, 2013

Hello. I'm developing a warp drive mod (thousands of them! )

The general idea based on teleporting vessel very very very fast (once per frame) using vessel.SetPosition(Vector3d position) method which makes illusion that ship is really flying whenever you need.

Everything works great expect of "through planet warp" and i asking you for help. I have serious language(english) problems and i suck at explaining things (Just wanna say sorry).

As i said i'm teleporting vessel every frame in target direction:

jumpToPos = vessel.transform.position + (TS.TargetVector * destination); //jumpToPos, TargetVector are Vector3d variables, destination is increases and decreases.

then:

vessel.SetPosition(jumpToPos);

but if new vessel position will be under surface vessel will explode (ORLY? )

so i have to check jumpToPos before jumping on it.

i can simple determine collision:

(x-a)^2 + (y-^2 + (z-c)^2 Mustn't be less or equals to R^2,

where a, b, c, R - planet position and radius

and x, y, z are jumpToPos values.

or:

(Math.Pow((jumpToPos.x - vessel.mainBody.transform.position.x), 2) + Math.Pow((jumpToPos.y - vessel.mainBody.transform.position.y), 2) + Math.Pow((jumpToPos.z - vessel.mainBody.transform.position.z), 2)) <= Math.Pow(vessel.mainBody.Radius, 2)

So if this condition returns true i shouldn't jump because of explosion.

But this thing work only if planet is a perfect sphere without mountains, hils and etc (nothing above sea level)

so i have a second check using raycast:

if (Physics.Raycast(jumpToPos, TS.TargetVector, out headHit, (float)(destination), 1 << 15))

and if this condition is true i shouldn't jump too.

Now everything is simple:

every frame i'm calculate jumpToPos and when it's safe to jump on i'm jumping on it, if not(planet collision) i'm just standing and waiting when jumpToPos will became safe again (flew from planet)

here's example (Mad skillz included):

where jumpToPos is A, then B, thec C....

When the vessel is at point C, next jumpToPos will be D and the raycast with length CD will say vessel to keep on C.

On the next step raycast from D to E won't find collision but E belongs to sphere and the vessel will keep on C too.

Same for the F point.

At the end vessel will jump to G and everything will be ok.

Just show a dark screen while vessel is holding on C

Zoomed:

But!!!

if more than one jumpToPos points will be below surface but above sea level there's will be a problem:

step 1: vessel on A, jumpToPos = B, B is safe(no collision) => jumping to B

step 2: vessel on B, jumpToPos = C, C isn't safe(raycast detected hit), keep vessel on B

step 3: vessel on B, JumpToPos = D, D is safe! No raycast hit, not belongs to sphere(red area), jumping to D and exploding!

So i need a 3rd check:

if(lastColAlt>vessel.altitude)
            {
                isSafeToJump = false;
            }

where

lastColAlt = FlightGlobals.getAltitudeAtPos(headHit.barycentricCoordinate); //from last raycast hit with surface

to determine if the vessel is under surface

Full code:

private void Jump(double destination)
        {
            bool isSafeToJump = true;

            if (Physics.Raycast(jumpToPos, TS.TargetVector, out headHit, (float)(destination + 50.0), 1 << 15)) //is any collision on the way to next jump point. Do it before calculating new jumpToPos value
            {                
                lastColAlt = FlightGlobals.getAltitudeAtPos(headHit.barycentricCoordinate);
                isSafeToJump = false;
            }
            if (lastColAlt > vessel.altitude) // if under surface
            {
                isSafeToJump = false;
            }


            jumpToPos = vessel.transform.position + (TS.TargetVector * destination);  // calculate next jump point


            if ((Math.Pow((jumpToPos.x - vessel.mainBody.transform.position.x), 2) + Math.Pow((jumpToPos.y - vessel.mainBody.transform.position.y), 2) + Math.Pow((jumpToPos.z - vessel.mainBody.transform.position.z), 2)) <= Math.Pow(vessel.mainBody.Radius + 5, 2)) // is next jump point belongs to planet(sphere only)
            {
                isSafeToJump = false;
                lastColAlt = 0.0; //drop value
            }

                ///Jump or not

            if(isSafeToJump)
            {
                lastSafePos = vessel.transform.position;
                lastColAlt = 0.0;

                vessel.SetPosition(jumpToPos);
            }
            else
            {
                vessel.SetPosition(lastSafePos);
                print("ABORT!");
            }

Now i have brilliant monkey code which works every 2nd time.

So...

Is there any way to check collision at point (like i can check altitude FlightGlobals.getAltitudeAtPos())?

Or any ideas?!

Or how can i disable collision at all?

vessel.GoOnRails() can't solve this problem.

vessel.collider retutrns null ref exception, looping from every part of the vessel and disabling collider has no effect, Physics.IgnoreCollision - nothing too.

Thank you for your answers!

P.S.

Thank you guys!

Also does anyone know how to disable ground collisions on active vessel?

Physics.IgnoreCollision has no effect and vessel.collider returns null reference exception

December 25, 2013

Is it necessary to create mod which located in GameData folder or can i locate it in Parts & Plugins folders?

November 22, 2013

SetPosition is the only func i can use for my "mod", i'll try to find more accurate position.

November 22, 2013

Thank you, i'll look for another way

November 22, 2013

Ah, solution always come after posting:

public override void OnFixedUpdate()
        {
            base.OnFixedUpdate();

            bug += vessel.GetWorldPos3D().magnitude - prevPos.magnitude;
            vessel.SetPosition(vessel.GetWorldPos3D() + (vessel.transform.up*(float)bug));           
            prevPos = vessel.GetWorldPos3D();           
        }

this works, but only in surface.

In orbit this is laggy as hell.

November 22, 2013

Greetings. Just wanna say sorry for my english, i hope you'll understand my question from code i posted below...

I've found a bug and looking for help to overcome it:

vessel.SetPosition(vessel.GetWorldPos3D());

sets the vessel a little bit behid from previous position.

For example i want my vessel to stay in current position:

public override void OnFixedUpdate()
        {
            base.OnFixedUpdate();

            vessel.SetPosition(vessel.GetWorldPos3D());
        }

but it starts flying backwards ( in vessel.transform.down direction) lol

This is my attempt to catch delta bug:

public override void OnFixedUpdate()
        {
            base.OnFixedUpdate();

            bug = Vector3d.Distance(vessel.GetWorldPos3D(), prevPos);       //here is it!   
            vessel.SetPosition(vessel.GetWorldPos3D(); //+ (vessel.transform.up * bug));   this will work every secon'd time   
            prevPos = vessel.GetWorldPos3D();

        }

The interesting thing is that "bug" is changing with speed, ship mass, and direction.

Any ideas?

October 21, 2013

blizzy78, thanks, this is way better.

I can't find that method, so i used a same one

vessel.parts.OfType<ModuleDeployableSolarPanel>();

but it didn't work. I'll figure out it later, anyway i understood how to control parts from code, that's all i wanted, thanks guys!

October 21, 2013

Oh yeah, thank you for your answer! Works fine.

I forgot about OfType<> method)

October 21, 2013

Hello.

I'm looking for solution to control retractable parts from a plugin.

For example: If your surface velocity reaches 10m/s, panels retracts to avoid breaking.

Unfortunately I'm stuck at this point:

PartModule[] parts = (FindObjectsOfType(typeof(PartModule)) as PartModule[]);

foreach(PartModule p in parts)
            {
                if(p.vessel == FlightGlobals.ActiveVessel)
                { 
                    if (p.ClassName == "ModuleDeployableSolarPanel")
                    {

                        //p.part.SendEvent(" whichEvent? ")
                        //
                    }
                }
            }

Thank you!

July 31, 2013

Yes, exactly! I made an unaccurate example with GetSrfVelocity(sorry) because i was looking for vector3d;

Thank you a lot!

July 31, 2013

Greetings! I'm looking for method or smth that will give me a coordinates of planets.

Actually i need a distance between active ship and target. Like a vessel.GetSrfVelocity().

Thank you for your answers!

June 25, 2013

Can't belive, but i found a solution:

WWW url = new WWW("file://" + "C:/....../Parts/TestPart/Sound/sound1.wav"); // or simply use KSPUtil.ApplicationRootPath to get ksp directory

audio.clip = url.audioClip;

while (!audio.clip.isReadyToPlay)
{

}
audio.PlayOneShot(url.audioClip);

It may be helpful!

June 25, 2013

Greetings! First of all i'm going to say sorry for my english, but i hope you'll undersand my question.

I have read some tutorials and tried to make an own small plugin mod.

I've created a module, which calls a GUI window with a button.

The OnClick() method cals even a button is pressed.

So now i'm trying to play custom sound in this meth.

Could you answer me where should i locate my audio file (for example - mysound.wav)?

Should it be in the module folder like a KSP/Parts/MyPart/Sounds/mysound.wav or in game recources KSP/GameData/Squad/Sounds.

What should i use to load it and play(WWW class with url linked to audio file) or Recources.Load() method)?

Should i create a new game object, wait when audio.clip.isReadyToPlay equals true and etc?

I've watched lots of posts and there are so many different ways to realise that, but nothing works.

I am grateful for any help. :blush: Thanks!
