Being developed using Unreal Engine 5.2 to learn MASS

5000(at startup) Zombies moving towards player car while avoiding each other and getting run over.

Zombies :

• They have a single animation made with AnimToTexture plugin.
• Their UV Channel 0 is overrided by AnimToTexture plugin(mesh problem) :( so they look a bit off when you close in on them.
• All of the meshes are Static Mesh Instance.
• They avoid eachother while moving towards player.

Zombie Killing :

• (Not Used) Killing Them With Collision :
  • To do this i had to use actors and that cut down fps by half.
  • Also you have to tinker with LOD too much to get even a okay result.
• Killing Them With UKismetMathLibrary::IsPointInBox
  • UKillZombiesInAreaProcessor checks every frame for overlaps.
  • Allowed me to use Static Mesh Instance in all Zombies.
  • Its a hardcoded box.

Performance :

• Fps is 25-30 in startup and goes up when killing zombies.
• I have a good gaming pc(3060ti 5600x) so 30fps is not fantastic.
• It could be way better probably. I will try to improve over time
