Making a qix type game.

You can do a flood fill to do that.

Basically mark all the tiles as not visited and then start with some tile and flood fill from that. Marking all the connected tiles. At the end any tiles not marked are isolated.

I guess the issue would be choosing which tile to start from. Maybe an edge? Depends on what you want to do.

Ok, so I made a tilemap, filled it with tiles, then made a sprite that moves one tile at a time that destroys each tile it touches. Then I want to destroy all tiles that have lost their connection to the rest of the tilemap.

So I can think of two ways to do it. Pixel/tile based or polygon based. Polygon based would scale up better with higher resolutions, and pixel/tile based is simpler but is slow. Especially with higher resolutions.

Here's a test of the tile based method with construct's tilemap.

My intention with this as with most capx files I post is just to give ideas.
