In this tutorial we'll be going over the better methods of drawing sprites, how to draw a background, and how to detect basic rectangular collision!

I know the audio is a little out of sync, but it's bearable..

I have very little expericence programming and my goal is to be able to create an overhead view game like Zelda. Your tutorials have helped me get a few steps closer and I'd love to see you go further in that direction. What I think ShortAndSweet means by "solid collision" is the sprite not being able to walk through the other sprite. Like a wall would be in Zelda. Not sure what to write in the second half of the if(playerRect.intersects(wallR­ect)) line. Anyway thanks I'm starting to get it :)

@BattleToads4ever ah, ok I get it. To do that, you have several options, none of which i've perfected. you can do a simple rebound collision. if(playerRect.intersects(wallR­­ect)) { playerPos.X -= 1; } and you can add a keyboard check along with that. if(playerRect.intersects(wallR­­ect) && keyboard.getstate(PlayerIndex.­One).IsKeyDown(Keys.Left)) { playerPos.X -= 1; } etc, etc. that's not the best, but it'll get you started.

@XSkullsGames LOL when i tried the keyboard check method you suggested, i got the player stuck inside the wall and i couldn't move!

[XSkullsGames]

@agentEE7 LOL, that'll happen ;) I've yet to find the perfect collision formula :O

[SuperShortAndSweet]
