thanks to Mark3146 and Jmal116 for helping, it now finally worked.
still trying to improve this stuff, getting it look better and stuff.
do you guys have a hint where to look for more guidance about command creations?
I really feel like getting into that stuff, but I'm struggling to get further than I am here.
working through the codes of some creations kinda helped so far, but it's not really the way you would want to go when trying to get things on.
I've been searching for some extended tutorials (or atleast a propoer documentation for the important stuff)for a while now but could not find much yet.
Using spawn eggs to summon these wayposts where you want them to be would be a nice thing to have and I think still basic enough to be something to start with.
@Oceanus5000 Because that's not at all I want it to look like. And in addition, you can target and take/destroy the head that way, so it's not an option for me.
Thanks again for helping me out,
have some nice christmas days everyone.
Greetz,
