Identifying Objets w/ scripting. Is it possible?

[roobre]

Hi!

I wonder if it's possible to identify objets in Algodoo using lasers.

P.e:

Code: Select all

onLaserHit = (e)=> {e.geom.is-a-plane}? {} : {e.geom.color := [0.0, 0.0, 0.0, 1.0]}

This code will change the colour of everything excepting planes.
Obviously, that code doesn't exists, but, Is it possible?

Regards

It is possible. use e.geom + "" to identify the type of object. Compare them by using strings.

Code: Select all

onLaserHit = (e)=>{e.geom + "" == "plane" ? {} : {e.geom.color = [0, 0, 0, 1]}}

To do that type

Code: Select all

(e)=>{ e.geom.density < 99999 ? {} : {e.geom.color = [,0,0,1]} }

Because a plane has no density.

Thankd guys!!

I'm going to test it now.

Happy Halloween!!!!

(e)=>{ e.geom.density < 99999 ? {} : {e.geom.color = [,0,0,1]} }

Because a plane has no density.

normally it hasn't but otherwise nothing in algodoo would have a density. because of that the density is defined as "mass per m²" instead of "mass per m³".
You just posted a code that changes the color of every object that has a density above 99999 kg/m² and basically no object has such a HIGH!!! density. in other words: nothing will happen.

The density does'nt work, i tried it yesterday.

I'll try The other way now...

The density does'nt work, i tried it yesterday.

like i said
standardtoaster's code will work. but instead of "plane" there has to be "box".

Code: Select all

onLaserHit = (e)=>{e.geom + "" == "box" ? {} : {e.geom.color = [0, 0, 0, 1]}}

Yeah, but i need that the script work w/ everything excepting planes, so it must to be "plane"

Oh sorry I posted the wrong code , It is supposed to be the other way around.

but then... what's a "plane" in algodoo?
