Need help with spawn engine

[alex55]

I did spawn the engine, but at a high speed transport the ball flies out of the engine.
To avoid this, I put "vel" in script:

Code: Select all

(e)=>{
    scene.my.xv = vel(0);     scene.my.yv = vel(1) }


spawner code:

Code: Select all

(e)=>{
    scene.addcircle({         radius := 0.5;         density = 100000;         pos := e.pos;         collideset := 5;         heterocollide := true;         vel := [scene.my.xv, scene.my.yv]     }) }

and it does`t work

sorry for bad English, I used a translator

That's because you have to make velocity calculation on your own. It's not implemented in algodoo so you can't just type in vel(0) and vel(1). They don't exist.

try setting vel in relation to normal like this:

e)=>{
scene.addcircle({ radius := 0.5; density = 100000; pos := e.pos; collideset := 5; heterocollide := true; vel := (e.normal * (some number))

you'll need to figure out how the 'some number' affects the velocity. I constantly have to adjust for objects going the absolute opposite direction that I want them to, the first time i fire up the sim.
