Provavelmente você está tentando acessar algo que não existe, talvez você tenha esquecido de anexar um GameObject ou algo do tipo em uma variável no Inspector, ou de anexar pelo próprio script.

Tem sim e so fazer assim tipo

Void start

Minhavariavel recebe gameobject.findwithtag ( tagdoquejvcvaipegar)

Tente substituir seu script por este, nao sei se esta correto pq fiz pelo cel!
Coloque a tag do Objeto no lugar indicado, comentei o Script nas linhas que adicionei!

e como eu faço pra qnd ele for criado ele ser filho de um canvas??

Public GameObject Canvas;
Void Start(){
transform.Parent = Canvas;
}

assim ou algo do tipo
