I was wondering, since I am creating a map that has editing using character actions and destruction coming soon (open world-large), if the tileset editor will be coming back. I know we have the tile sprite object, but its not the same. I think that editor does wonders for the software, and if it is still there I cannot find it 
Tilemap object is a native-only extension (was never developed for web), so it isn’t available in GD4 HTML5 projects nor GD5 (GD5 supports web platform only at the moment) 
Oh ok gotcha That’s cool though! Ill find a way Maybe 0 alpha collisions and sprites that change based on those collisions 
Any prevision on when (and if) we will have tilemap in GDevelop 5?
It is on the roadmap. You can vote it up to make it a higher priority:
