Hi!
I am new to programming and I’m making my 1st game. I want to teleport my character to a knife that he threw. Please see the details below:
-
I tried transform.position = teleknife.transform.position; but this causes him to teleport to the location of the prefab. I learned that it should teleport to the clone. I don’t know how to do this hehe.
-
The coding is structured this way: The KNIFE is thrown by JARRED which inherits from CONTROL which inherits from CHARACTER. I’m sorry if the code seems confusing. I hope you guys can help! Please see the C# scripts below:
