So i started building some more maps and have come to realize that with blizz ABS maps have alot of problems, randomly some of my X on passability all of a sudden can we walked straight through and then at random other squares on the map just become unpassable? Is there any fix to this?
It's not Blizz-ABS, it's just mistakes in your passability. Make sure that on the layers above you are using the clear tile in the upper left (I think it has max priority, but I might be mistaken), and not another clear tile.
If it really was BlizzABS, you could just move the scripts below 'Main' and run the game again. If the map problems still exist, it's not the script.
OK so i removed blizz abs and all worked perfectly, so then i went back to my project and used the top left corner square to define all the map spaces that are blank and it has worked, i think something in blizz abs must be more strict than without?
