Udon flocking

Hello, I’m new to making worlds and have been trying to get flocking behavior for certain objects in my scene. So far I’ve been trying to code them through Udon#, but I often get “method is not exposed to Udon” when attempting to Instantiate

Can’t seem to get VRCInstantiate to work through Udon# as well, and I’m honestly stumped as I’m new to most of this…

Can someone help me make this flocking system?
