setRadius(); in physics2d (toxiclibs)

in Contributed Library Questions • 2 years ago

Okay, I just have a quick question. I'm tried to use setRadius() on a physics2d AttractionBehavior instance and in return I get told that it's set to private. I've been looking around the source files for a bit now and saw that it has been turned public since a while.

The problem is this. I havent got the slightest idea about how to compile all that stuff though. Could someone either provide a link to the updated lib or, preferably, explain me how to compile a .jar from the source files?

Cheers.

I had a similar issue recently. My solution was much simpler than recompiling anything. Rather I just removed the existing AttractionBehavior and created a new one with the proper radius. Depending on your application this may or may not be a good idea though. For me I was only updating the radius every so often, but if you are going to try and do it every frame or something, this may cause problems.

Yeah I have at max 50 updates a frame (no biggies though). Just tried it out though, and the ABH seems to live a live of its own :/

Oh well, tomorrow is another day.

Until the 0021 release will be out, just subclass the AttractionBehavior and inject your own setter method (sorry about that private method mistake too :)

class MyAttractor extends AttractionBehavior {
public MyAttractor(Vec2D attractor, float radius, float strength) {
super(attractor, radius, strength, 0);
}
public MyAttractor(Vec2D attractor, float radius, float strength, float jitter) {
super(attractor, radius, strength, jitter);
}
// we basically inherit everything, but provide our own setRadius() patch
// AGAIN this is only needed until the release of the 0021 version of toxiclibs!!!
public void setRadius_patched(float r) {
this.radius = r;
this.radiusSquared = r * r;
}
}
