Also I just pushed the github again if you need to see the code

It stopped crashing!
but the projectile is still invisible

oh nvm that is just an issue in my renderer

 

[me.jo.be.BedrockThings/]: ClientPlayerEntity['Dev'/1, l='MpServer', x=215.40, y=3.94, z=339.80]  !=  ClientPlayerEntity['Dev'/1, l='MpServer', x=215.40, y=3.94, z=339.80]

 

Thank you
Everything works now
