I’m creating a topdown rpg and I need to spread random vegetation all over the map without leaving trees above the town.
The idea was to create an invisible layer and spread the green tiles over the parts of the map that shouldn’t have trees, but when I tried to use tileIndexCallback to kill the tree sprites nothing happened.
help.
A picture of the map in Tiled
Green tiles should not have trees or grass because it is where the town and the forest paths are
Show code?

I run the game and the town looks bad
