how to make a rotary collide eng.

[hecta]

after one million failed atemps at a throtelled rotary engine I decided to ask for help so.. how to make a good throttled rotary collision engine (mine has unstable rad/s and works badly) please help

Start by making a very simple collison engine, then change it to have a throttle. (The throttle just changes the ignition timing, basicly by rotating the "spark plugs" so the collisons last for longer (Faster rpm) and shorter (For idle).

o.k so i did that but why does it explode when I grab it or when i lower the throtle whit down arrow ?

I dunno, you've just taken a picture of it.

I added an atachment at the top

it explodes when you throttle down because the red circles don't turn green (and thus change collision layer) before they re-intersect the red box

try reducing the size of the red box to half, and see what you get

thanks works ! it goes from 4 rad/s to 22 !
