I'm using tiles from the Open Bundle, which someone AWESOMELY linked me to earlier, and...
I will give an example. Each tile from the tile folder from the Platformer Pack is 70x70. Is there a way I can turn the entire folder into a tilemap, or at least force a grid to be 70x70 in Paint.net or GraphicsGale or something, so that I can import it easier?
It may sound very dumb but I use C2 itself to assemble them, I'll explain:
1/Create a new project, set the layer transparency to Yes, and insert the browser object
2/drag n drop all the tiles in C2 at once, it'll be one unique sprite, put it outside the visible part of the layout
3/create 1 variable global: TilePerRow (which is the number of tile you want on one row at most)
4/Set the window size to the size of the tilemap you want at the end, and set the fullscreen in browser to Off
5/add an event on start of layout> Repeat Sprite.AnimationFrameCount ;
system >Create object Sprite at position
X:(Sprite.width*(loopindex%TilePerRow) + Sprite.width/2)
Y:(Sprite.height*int(loopindex/TilePerRow) + Sprite.height/2)
Sprite: Set frame to loopindex
and another event: On canvas snapshot: Browser, invoke download SnapshotCanvas , name it "Tilemap.png"
Preview, and wait for it to be downloaded, congratulations, you have sucessfully managed to do it, the tilemap is normally in you download folder.
Should work easily
