Read some things and heard about a CSV plugin being able to use an array to generate the level for a tileset, but also heard arguments against using all tiles due to performance issue.
Would it be best to use a giant(depending on level size) tiled background image for all the "background" tiles and then have only the solid ones in an array to be generated?
The software I use to generate my tiles is a great one called Pyxel Edit ( http://pyxeledit.com ) which has options to export the tileset as a png file along with a text or XML document of their placements
Text format (no rotation/flip information as of yet, hopefully next update)
XML format (includes rotation/flip information)
(-1 means no tile placed there)
Sorry if the post is a bit long winded, so I'll just reiterate things succinctly here:
1) Performance wise: Better to use all tiles or tile-solids with a large background image?
Edit:Apparently tiled backgrounds blur when resized while sprites do not, and sprites do no blur if webGL is enabled. So I guess all tile sprites is the way to go
2) Instructions: How would I use a CSV file to make a level map ; or the XML file?
