I was able to get everything setup, using this:
>root -> prio=0; blending=none
>look & headside -> prio=1; blending=root
>standing side -> prio=2; blending=none; cycle
>standing forward & back -> prio=3; blending=none; cycle
>crouch -> prio=4; blending=none
>crouch side -> prio=5; blending=none; cycle
>crouch forward & back -> prio=6; blending=none; cycle
>jump & stand jump -> prio=7; blending=none
>fall -> prio=8; blending=none
>armReady & spear charge-> prio=9; blending=none
>attack, activate, & build -> prio=10; blending=root
>death -> prio=11; blending=none
I am crashing for some strange reason after fixing some animations and setting priorities. I was able to run the game before fixing some animations, which all I did was flip around (they were facing the wrong way, flipping the camera around to the front)
The console shows no sign of crashing.
I only crash after trying to change the player's datablock with events.
