This is sorta related to my last problem with the sprite not being able to move. I found the problem that it wasn't the sprite, but the floor tiles I was using. And now I wonder if there's a way to fix that problem.

The sprite moves well on the original tilesets given to me, but it won't move on other tilesets I've downloaded. Yes, I've gone to the database and checked, double-checked, triple-checked, even quadruple-checked to see if the tiles were still labled as O's. And they were. But the sprite STILL can't move on it (and there was even a time where I replaced the downloaded floor tiles with the original ones and it couldn't move on it, but it worked when I re-made the map over again.!)

Please help!

[but it worked when I re-made the map over again.!) ]
if it worked, so whats the problem?

dunno what program that u used, maybe its the paralel/autostart?

Sounds like you accidentally flooded your map with a invisible tiles. It would explain why you didn't notice the problem and why doing a new map helped.

I meant when I remade the map over and used the original floor tiles. But when I remade the map using the downloaded floor tiles my sprite still didn't move.

Is there anyway to change invisible tiles to passable tiles?

Why is this in visual art and what engine are you describing?
EDIT: Never mind I found out, but this is still the wrong forum. Moving to it's proper place.
