hmm

Fixes to every attached actor not getting cleared.

Fixed lag because the every attched actor table would never get cleared when called so it just kept getting bigger when a player touched a block causing lag. when a block that was placed by a player falls onto a world placed block it now becomes player placed same if a world placed block falls onto a player placed one. Tools no longer attack dead zombies

Fixed player collision blocking gun from shooting. Fixed tools doing no damage

Fixed it so when players touch blocks zombies will now attack them properly. Added Debug text for tool damage

Tools do damage( zombie health / wave * zombie damage multiplier (wood tools = 0.75)). Zombies will now attack world placed blocks only if a player touched them. Knifes have haptic feed back when stabbing

Fixed leaves spawning as oak logs. Fixed the method to fet the nav path using the zombies location instead of player.

Added better path detection so instead of checking if a path length is greater than 0 to see if its valid now it checks if the last nav node is a meter and a half or closer to the player. Made it so if the closest player is closer than the closest block the zombie will go after a player instead

Zombies now attack player places trees to prevent walls made of trees. saplings no longer have collisons

Fixed blocks going to 0,0,0 if the raycast hit nothing, Fixed the bug that made players unable to pick up items, Zombies no longer stand still if players are farther than 10 meters and there is no player placed blocks
