lRELEASE THREAD: http://forum.kerbalspaceprogram.com/threads/55805-WIP-B9-SOON-PROE-Prototype-Optimize-and-Enhance-%28KSP-Engine-Tech-Tree-Mod%29 I am working on a mod for ksp that integrates different tiers of engine into KSP; In the mod all engines in the game (and possibly B9 and/or KW) will be organised into tiers that will be researched via the tech tree! For example the trusty old LV-T30 will first have to be Protoyped, then crudely made and then upgraded to the normal level where after it can be optimized and augmented for more thrust for efficiency with a trade-off of the other. I hope to make this mod so players cannot get to orbit with tier 1 and magically hyper-efficient xenon engines will have to be thoroughly researched and refined. The tiers are as follows; LIQUID & ION Prototype All Engines will be prototyped at first and will be much more fragile and inefficient. <Very Expensive = Its a prototype!> Crude Some engines will be made crudely and will be cheap but still inefficient For Jet Engines and 1.25m to 3.75m rocket engines. <Very Cheap because of basic materials and concepts> Radialized Radial engines will need to be unlocked by researching the engines they come from and will have normal stats. Where applicable, includes VTOL <Expensive> Normal Just the normal stats. Optimized All engines will be optimized and all stats will be better because of removal of useless parts and good engine settings. Slightly improves attributes <Slightly Cheaper> Augmented Augmented engines are modifed engines to add or improve an attribute but detriments another attribute. For SABRE the LV-T30 Rocket AND the B9 High Altitude Jet must be at enhanced level, For Hybrids the rockomax 0.625m inline engine AND the PB-ION thruster must be Optimized. Jets and some 1.25m-3.75m rocket engines, improves thrust or efficiency but makes the other stat worse Includes SABRE and hybrid thrusters. <Stupendously Expensive> Enhanced Very Expensive, Very Light, Very Efficient is the motto for the Enhanced Tier making it the best achievable all-round improvement available. Final Tier and will only be available on a small amount of rockets but attributes will be improved 10%-20% <Very Expensive> SOLID ROCKET BOOSTER Crude The original boomstick, low thrust - alot of bang. Crude Solid Rockets are the first foray into rocket science, cheap and totally inefficent Normal Standard SRB's "Nuff said" Thrust Augment Using more combustible fuels rockets burn more powerful but shorter. Higher thrust is a trade-off for a worse ISP. Efficiency Augment Using slower burning fuel these rockets are more suited to lighter loads. Lower thrust is the price for a much slower, efficient burn. STILL CONFUSED? This (More Coming) flow chart helps you visualize the tech tree .DETAILED DESCRIPTION OF TECH TREE Liquid CREDITS: -Harrison11 (Coding) -r4mon (TreeLoader) Version History: - v0.1 First Release, only SRB's and Prototype stock liquids. - v0.2 Latest, all non augment liquids and all SRB's done! Augments and Science next update! TODO: - Integrate into a new tech tree - Figure out how to delete parts when new parts are researched - Finish Stock - Add B9 Aerospace support (Most Requested) - Add KW Rocketry Support - Make Hybrid Ion engines Feel free to do anything with PROE as long as you do not distribute without my asking, rename it as another mod or use any assets in the mod without credit and permission. If the mod is inactive (No news or login from me) for 45 days the mods updating and upholding will fall to the public until I can return. P.S Please don't bug as I have to reconfig all Stock,KW and B9 engines 5-8 times and any help would be amazing!
