LuaEntity::can_teleport(position, surface)

Checks if the entity can be teleported to the pos/surface without actually moving the entity.

What is the use case?

Picker dollies

I could fail a lot earlier on things that can't be teleported without having to restore everything, Mostly on stuff with fluidboxes that can't be mixed.

And this gave me another idea! it should also return true if the only thing stopping it from teleporting to that position is itself. (This should also apply to LuaEntity:teleport also)

Can you just create same entity and destroy it?

LuaEntity.teleport() already works fine for distances smaller than the entities bounding box. So can_teleport() wouldn't help you if you also need to know if the target position is non-colliding, because teleport doesn't care about collision.

Wouldn't it be more useful to have a LuaEntity.non_colliding_teleport() or Surface.find_non_colliding_position{ignored_entities={}}, then you can call that and if it succeeds you do whatever other special treatment the thing needs?

(Btw, i saw a funny bug in dollies on the arumba stream (one of the first three videos. Where he dollies around a PY tailings pond, but that is a compound entity so it only dollies half of it. You should not dolly anything if there's more than one entity at that position.)

Yeah after posting and thinking it through some more it wasn't teleport that was the total issue it was can_place_entity. can_teleport would still be nice, but can_place needs the ignore entity check

Does nobody report bugs!!!!!!1111111one I'll fix the py thingie
