Another cool spawn tech!

I've found new interesting way to spawn objects with dynamic properties

I use class object scope operator "->"
in that way all custom properties (like ttl in example) are stored inside box.

example:

Code: Select all

(scene.addBox {pos := [1,1]; size := [1,1]}) -> {
    color = {[1,1,1,sin(sim.time)]};
    ttl := sim.time;
    density = {sim.time > ttl + 3 ? 0 : 2}
}

Wow, really helpful. Now I can solve my dynamic tracer mystery. Thank you!

Brilliant!! Now I can make realistic tracer-clouds if I understand this properly... what does "ttl := sim.time;" mean?

ttl is a custom object variable
and if you don't know, when ever ttl is read, it will give the value that is stored in sim.time (or whatever ttl equals)

...what does "ttl := sim.time;" mean?

it's a time marker. Saves the time in ttl-variable when the collision occured.

or that.... Forgot it had to be in brackets fot the thing i said...
