zooming in toxiclibs physics --> physics.setWorldBounds?

in Contributed Library Questions • 1 year ago

Hi,

i build some system based on the toxiclibs physics.

I need to scale and move around in this system, something like a camera.

my question is now, since you set the "worldBounds" to the physic system, how do i work with that?

could i use a peasyCam and try to update the worldBounds to that area my camera sees?

or is it better to stick to the worldBounds and scale and move inside them?

what would be a appropriate approach?

Thanks!

You don't say if this is a 2D or 3D sketch. But since you mention peasyCam, I am assuming it is a 3D sketch.

If all you want to have is a camera to move around the system and zoom in and out, then the easiest solution is indeed peasyCam. This was exactly the purpose of peasyCam, to be able to add a camera to any 3D scene with only a few lines of code... easy-peasy. For more advanced camera movement one can turn to Proscene.

I don't see a connection between worldBounds/physics and a 3D camera. And since you do mention those a lot, I am wondering if you want something else or something more than just a 3D camera. If so, elaborate what you want exactly.

Hello,

thanks for the reply! Perhaps i wasnt making my point clear in the first post.

By now i guess i already know some parts a bit better … but i try to describe my thoughts and problems again

I had a 2D physic system with particles. Like items on a table and you look on it from the top.

I thought that the setWorldBounds were a necessary thing to make that whole thing going, but as i found out, it also runs without the statement, which makes me believe that its rather a thing to keep your items together or save performance.

Before that conclusion i was thinking of how to keep the relation between the area the camera sees and the worldBounds, which is as i found out not necessary.

Thanks
