Sprite zoom/scale functionality?

by Jason McIntosh · in Torque Game Builder · 03/11/2005 (10:34 am) · 5 replies

Will there eventually be a function to smoothly scale a sprite from one size to another? I know that you can set the size, but that doesn't exactly scale smoothly between one size and another. :) I seem to recall that you can use particles for this or somesuch? But I'd like to have a pulsing image without using a particle for it.

Edit: I'd also love to see this for color blending so we can fade in/out individual sprites smoothly.

We'll eventually be aiming for animatable properties for practically every T2D object property, very much like the key-framed system used in the particles. This is why we don't want to put too much effort into animated functions immediately.

Pretty easy to do all kinds od stuff if every sprite could have a callback called once every fraction of a second or so.

You can set up a callback like pattern in a number of fairly streightforward ways. One is to have a method or function that scheduals a call to itself:

function fxSceneObject2D::callback(%obj) {
    // do something interesting here...

    %obj.schedule (125, callback) ;
}

Another (untested) idea would be to stick all the objects you want to participate in the callback in a SimSet and have something that calls a callback method for each object in that set every x milliseconds. This would make it pretty easy to "register" a callback; all you'd have to do is add it to the set.

Greg is correct. There's also the update-scene callback although you can hurt performance if you do too much there.
