how can i bind a key to a certain collision

[kronicphun]

is it posibal to have a certain key activate when say ... geom. A collides with geom. B

No, but you could cause an event by executing a function in the oncollide...

The simpliest way to do this might be using a laser.


You can make a key controlled laser and set the onLaserHit variable in the script menu to: (e)=>{e.geom.collideset=whateverCollidesetYouWant}.
This would make a laser change the collideset of the objects it hits.

Instead of whateverCollidesetYouWant type:
1 for A
2 fro B
4 for C
8 for D
16 for E
...
For instance, if you want a B collideset, make onLaserHit = (e)=>{e.geom.collideset=2}
If you want it to be A and B, type 3 (1+2). B and D would be 10 (2+8). A, C and E would be 21 (1+4+16).

Another better method is to do the following:
1. Open the console (press tilde, F10 or F11 - depending of the version of Algodoo you use)
2. Declare a scene.my variable - for instance, type scene.my.collideset := 1 and press enter
3. Make a few key controlled lasers and a box for the lasers to hit it.
4. Set the onLaserHit of the lasers to (e)=>{scene.my.collideset=whateverCollidesetYouWant}.
5. Set the collideset in the script menu of your object to collideSet = {scene.my.collideset}.

See the attached scene.

If you want to turn on a motor or laser onCollide, you can use maxRays = 0 to turn a laser off and maxRays = 1000 to turn it back on, or for motors you can turn it off via motorSpeed = 0 for autobrake or motorTorque = 0 for non-autobrake, and set either of those to any other value to turn it back on...

Do exactly what the second part of Ivan's post says, only with scene.my.maxRays or motorSpeed or motorTorque... ... ...
