Editing pos we can teleport an item, but whole instance instantly go from one place to another unlike an item through portal that each side have part of thing.

I don't know how much you know about algodoo geometric objects, but a chance would be to manipulate the surfaces of an object. You'd have to save the surface entries, delete old object, manipulate new surfaces slightly and spawn a new object with these. Also you'd have to save and continue old speed, position and the collision position etc.
You get positions with e.this.pos or e.other.pos for object position, e.pos is where collision event happened.
Paste this into your console to experiment with:

Code: Select all


scene.addCircle({
  radius := 3.4;
  collideset :=1 ;
  onCollide := (e)=>{
        scene.addCircle({
            pos := e.pos;
            collideset := 2;
            timetolive := 1
        })
   }
})


Not gonna lie, sounds difficult. I experimented a bit, but saw no easy way. Something with object manipulation i saw a long time ago would be this:

You can get the surface data by copying the whole object an pasting it in a text editor (if you paste it into algodoo console, it will spawn the exact copy of the object).

Code: Select all

you could copy this code, paste it into your console and get a half circle object.

Sorry, that's likely not what you asked for, just my two cents. Maybe others can help better.
