Даже буду добрым и предоставлю все сразу на языке, понятном Аурану:
Script API:
1. Vehicle.SetTractionMultiplier() is not working. We tried to use different values with it, turned sanding on and off and none of this makes an effect.
2. A function to directly adjust a tractive and brake forces to a vehicle. Currently we are using a some kind of hack to set traction force and to shut down "cold" locomotives.
3. An ability to control pressures in brake systems (at least in aux reservoir and brake cylinder) — currently we are using a hack too to get realistic brakes working.
4. There is a need for more algebraic functions in Math class (sin, cos, log, power for example).
5. Soup has a performance problems if it is used frequently.
6. Cabin.UserPressKey(). When I press and hold the key, the function is called, then there is a pause for about 0.5sec, and then it is called in every frame. This pause creates problems when I use the keys to control the whistle, for example. I know that it was done to make control more comfortable, so this fix may be done by declaring the keystrokes which will not use the pause, or something similar.
7. New kind of controls in cabins — a button which is activated only by a click (not a click-drag like others). This is mainly needed for the use in electronics' keyboards.
8. Some camera control functions to adjust and get camera position and orientation (which is displayed in bottom-left corner on the screen: XYZYP) in a cabin's local coordinate space. This is suitable for realistic cabin sway and movement constraints inside the loco.
9. A system that allows communication between Trainz scripts and outside applications.
Sound:
10. Doppler effect. It's 2011, I think it's time for Doppler
11. A script features that grants control to a sound pitch. It is necessary for traction motors' sounds, ventilators, turbo compressors of diesels.
12. An ability to change the volume and to stop playing sound.
13. An equaliser for the sound (optional, this can simplify the creation of cabin sound set).
14. Previous two paragraphs can be implemented by adding some script class, which will represent the sound itself and give an access to its properties and playback control.
Graphics:
15. Working at daytime headlights. Currently headlights are cut down in 5 o'clock and are returned back at 18 o'clock. It looks very ugly. The best solution is to smoothly adjust headlights' intencity using an actual sun light power (not the time) or/and grant a control of this to a script.
16. An ability to get an actual diffuse light power/color. This is useful for realistic loco inside lighting.
17. An ability to adjust headlight color (SetHedlightColor() does not solve the whole problem), intencity and light cone parameters. The default light's look is pretty unrealistic and it will be great to have an opportunity to fix it.
18. There is a bug in tracks appearance. They has inverted light normals. At the moment we fixed it using the normal maps, but in future it will be good to see this problem fixed. For backward compatibility it can be provided with an additional config tag.
19. Self-illuminating particles. Their self-illumination makes locomotives' smoke effects ugly in the night. It will be good to have a tag in confing, something similar to tag "light" for scenery objects, which will enable a dynamic lighting for particles.
20. Self-illuminating "text" effect. Problem similar to particles — sometimes there is a need to have not illuminating texts.
Ауран меня с этим списком послал в жопу, если что. Ждем новостей!
