Sprite collision detection

I'm currently writing a game in which you control a little
character with a gun.  But I was wondering how I could detect wether or not the character is standing next to a wall.  Right now, the character runs through the wall.  I've used the div function to check the sector next to the character to see if its blank, however, the character can move into the next sector before he is "in" the next sector and thus is drawn half way in the wall.  How can I detect if the character can walk to the right or left?

Generally, two different objects cannot occupy the same position in space. One way to know if something is going to collide is to compare the two rectangles for the objects. If there is an intersection between the two rectangles, then there is a collision. To detect if something is going to collide, then you would use the imagined new positions for the moving objects and intersect them. If there is an intersection, then the new positions cannot happen.
