Still need help with blockers...

Fox,

I checked out your tutorial... It was great!!! I was able to add some much needed effects to my little game... but I didn't see anything that covered blockers... What I need is to prevent my character from passing over an object or a certain tile type or "number"...

Another thing...

I checked out your tile engine, and I didn't see(or understand) how you can change the map to better suit my needs. I understand that you use different pictures for the tiles, but how do I get them to be placed where I need them???

Thanx for your (or any1 elses) help,

Squirrelly1:D
