Tilemap Unresponsive Script

  • Problem Description

    Loading layouts with a 2048x2048 Tilemap in them causes Unresponsive script error (tilemap_plugin.js or glwrap.js) in Firefox and noticeable delay in other browsers (Chrome/Edge/IE). Game will eventually run on Firefox as well if the script is continued despite warnings. Changing the source image did not affect the issue.

    This issue also persists after the project has been exported and my friend reported the same error when playing my game on Firefox.

    I thought there might be something wrong in the Tilemap-plugin so I tried reinstalling C2 and installed r245 Beta but it didn't solve the issue.

  • Your tilemap has over 16,000 tiles in the tileset image. Is this something you really need? It seems like a case deliberately made to be slow. C2 has to cut up the tiles from the tileset image when the layout starts, and it seems Firefox is slightly slower at doing this, and takes long enough to show a warning.

    Unless you have a real-world tilemap that does this, and you can't make it smaller, closing as won't fix.
