Thanks Mernom, I know how do it, but I haven't time.
I see u made other bridge mod, if u want u could do it urself, and if could help u, from my library (aswil) u could call:
aswil.entities.removeCollisionMaskOnEntity(category_name, entity_name, to_remove_mask_name)
replacing argument "to_remove_mask_name" with "space_collision_layer" and other argument how u know ;) (for each entities, category name of entity and the name of entity of the mod)
