Zurvive Version 0.0.3

Finished work on the health and survival basics.
Most stuff is in the background and will only become apparent if you play longer stretches (hunger/thirst).

The zombies now react a lot better and will also hit you when they get close, damaging and killing you.
For this purpose I made a quick deathscreen as a placeholder.

I also started a discord to follow the development: DISCORD

CHANGELOG

-> ADDED 

• Zombies now use a NavigationAgent3D with a NavigationRegion3D in the level. 
• Small additions to Testmap 
• Redone Shooting; bullet is a projectile now 
• Reworked gun position & look_at for more realistic bullet collisions 
• Small tweaks to the Zombie state handling 
• HUD, representing the health and survival system (BASIC) 
• Zombie Attack state 
• Death animation ; you can die now! (press P to reload level) 

-> CHANGED

• Zombie AGGRO state tweaks
• Zombie FIGHT state tweaks 

-> KNOWN BUGS 

• Audio glitch in slowwalk and crouching. Speedchange footsteps glitches
• Zombie aggro behaviour sometimes misfires or has weird reactions (need narrowing down) 
• Zombies will redo their death animation if you hit their hitboxes again. These aren't animated yet.
• If you run past a zombie real quick and close it loses AGGRO and goes into the SEARCHING state, which isn't implemented yet
