As a lesson, today I taught myself that sometimes your first (several) attempts to Google a problem just don’t do the trick. For several weeks I’ve had an issue where my mobs just zoomed around like they’d been snorting magic dust, completely ignoring the values set for them with regard to speed, acceleration, et cetera. It happened fairly suddenly, I wasn’t sure why, and many attempt to fix it failed.
I Googled this issue many times over the weeks looking for an answer. Nothing relevant ever seemed to make it into my search results. It became frustrating!
Then, on a whim, I searched once more for the answer, clearly using a better phrase, and Google’s magical algorithm finally decided to lend a hand. Of course, the answer was something dumb on my part. At some point, the isKinematic boolean flag on the rigidbody component became unchecked, which meant that the rigidbody and the nav mesh agent were in a race condition, both trying to control the movement of the mob.
But, NO MORE! My gel cubes gracefully slog around the dungeon biome again, and the War on Magic has been brought to a halt.
One checkbox took weeks to resolve. Probably a n00b issue, but a good lesson all the same.
