Getting started with UnitySteer




UPDATE: The last 2 major releases of Unity adversely affected how UnitySteer steering behaviours play with non-kinematic RigidBody components. If you’re having trouble combining your physics with steering forces, see this enhancement I added, which may or may not become a pull request at some point (although I think the UnitySteer project is not actively maintained any more).

There are several AI steering libraries available for Unity, but I settled on UnitySteer due its similarity to OpenSteer for C++. Continue reading Getting started with UnitySteer →

Since then, I’ve used it quite a few times, in order to speed up apps and improve resource management, easing the load on the garbage collector by reusing objects instead of recreating them.

But I recently needed a solution the didn’t depend on external JavaScript, due to not having control of the page the SWF is embedded in.

With my simple FlashSize script, all you need do is call:

import com.spikything.utils.FlashSize;
FlashSize.setup(minWidth, minHeight);
