Dear SupportiveEntity
Thanks for the quick response. I’ve tried some things out but I don’t understand it completely how I have to do it exactly right because my ‘technical term English’ is not so good. 
Is it possible to draw it out in nodes like you did the first time?
For the loop issue. I thought I was generating 10 tiles at once at the start and everytime I collided with the collision box the last one was destroyed and a new one generated. This for infinite times.
Thanks in advance!
Michiel
