its easy to make a spwan engine, just copy and paste in a code for spawning circles.
I don't konw if I've released any of mine, but here is a script to get started.
Simply change the different variables to make it yours.
To change the collision set, make a new object, set it to the desired "ABCDEFG" layers and check the scripted collideset. For instance, A & B is combo #3
collideset := 1; <------------
Yep, it's probably my favorite.
If you want, you can attach a wheel to the clutch outer ring, and then put a dummy wheel on the front. It demonstrates the power of it!
The clutch was not made for the engine, so coincidentally it might now work very well... It was really made for the Variable Spawn Engine, in which is perfectly tuned.
@bluebravo
find your color values (for both on and off numbers) and set it to which color you want by scripting it
then have each gear have their own variable
Example:
Gear 1 color: scene.my.gear1color
(your trigger for on): scene.my.gear1color=[on color value]
(your trigger for off): scene.my.gear1color=[off color value]
It's wonderful, but I seem to have a small problem, it's that when it is stopped it doesn't output a consistent 0 value, so it goes to "NaN" which is probably infinity. This makes my needles on the dashboard spaz about when values are supposed to be 0. I am runnning 2.0.0 "RC1".
