I am learning Unity and currently I am working on a prototype of a 2D, true top down snow plowing game. The challenge I have run into is of course simulating the snow to be plowed where the simulation easily brings down the frame rate. I started off with very small snow game objects with circle colliders on them. That looked really good small scale when moved by the plow truck but quickly crashed my frame rate when the particles grew in numbers. Right now I have medium sized snow game objects that have colliders about one 5th of the size of the sprite. This way the snow can be “packed” together by the player driving the plow truck. I have made a script that makes all snow game objects kinematic untill they enter a trigger collider on the player. The snow game objects regrettably look more like like cotton spheres than snow, but the game sort of runs. The frame rate also drops horribly low when I pack alot of snow together and move it together.
What I am trying to get at is a satisfying experience of plowing snow with a truck in 2D where the player can move and pack snow together with the plow. Any thoughts or advice as to what I could try would be appreciated.
