Check object existence

[0xB10C1DE]

I tried to check some object existence by Scene.entityByGeomID(x)
But if x pointing object were non-existence, console said

Failed to find entity with geom id: #x

I tried this script

Code: Select all

Scene.entityByGeomID(x) == undefined ? {} : {} 

x is a random number

but a conditional sentence don't work from the beginning


Is there checking object existence method in algodoo script ?

sorry, I borrow google translate power

I've try something like that, usin xFor() to find all entityes by ID. It works but very long (about 30 sec)

Code: Select all

scene.my.xFor = (n1, n2, code) =>
{n2 > n1 ? {m := (n1 + n2) / 2; scene.my.xFor(n1, m, code); scene.my.xFor(m + 1, n2, code)} : {code(n1)}};
scene.my.all = [];
scene.my.xfor(0,65535,(id)=>{scene.my.all = scene.my.all ++ [(Scene.entityByid(id)).entityID]});
scene.my.all

Code: Select all

_entityExists := (eID)=>{
   rtn := false;
   (entityByID(eID)).entityID > 0 ? {
      rtn = true
   } : {
      rtn = false
   };
   rtn
};
