Hello, I'm working on a plugin to add collision between player. It work like that: If i'm moving fast: Knock, else, just stop it. Actual problem is : Sometime player seems laggy when knockacked Partially solved by adding a tick system (Seems because i'm too close to the player, and plugin get called another time) I've tried to change the system knockback to prevent the player to go inside the other player, but if i stop him, and player too close of the other player, you'r locked. If you try do to calc on speed of the player, and player fall a stair and collide plugin called, your speed is very high (Fall) and you kockback is high too. If i use that, maybe it will be possible to cancel fall damage by jumping on a player ? Any advice, or help are welcome Thanks.
