I've seen quite a few posts now with people asking for help on 2D tile maps and collision detection for a character jumping around so I thought I'd put together a sample.  It's hopefully fairly simple but I thought I'd get people's opinion on it before officially putting it on my website.

TiledLevel sample

It consists of an .html file describing the key bits of the source (drawing the tiled map and collision detection with the map) and a complete .sln which builds for Windows.

If it seems useful I might add more but this seems like the most basic fundamentals to getting such a game running and I don't want to confuse people with code they might not be interested in.

Hey, Dave, I think it looks really good.  I wouldn't add much more to it -- I think you're right that it's best to keep it to the basics.  I found it very easy to look through and understand.  My only disappointment was that there was no princess at the top!  ;-)

Thank you so much for taking the time to do this. I love platform games and having a core framework like this to reference really means I can get on with trying my ideas out instead of spending weeks or months writing the engine.

Cheers - I owe you a beer.

the last platform is impossible to get to.

god.

The map is actually randomly generated to keep the code simple.  It's possible you can start completely wedged between two platforms as well.  Just run it again.

I've just added a second part to the Tiled Level tutorial on my website.  It adds coins which the player can collect and blobs which will hurt the player, it also covers managing all these objects in the level.  I've still tried to keep everything as basic as possible and show how the core mechanics work.  As you can tell by the graphics used it's not particularly flashy! :)

If anyone has any suggestions about what they'd like to see added to these tutorials you can drop an email to info@smudgedcat.com.
