Intersect Rect

I'm having trouble with collisions..

i am drawing a map using an array of tiles (which are picture box's) and i have been told to make a tile collidable i need to use intersect RECT

can anyone tell me how to do this?

Cheers

The reason why most games don't use pictureboxes for each tile is that it requires 4 draws of the character, one for each part of a picturebox he's in (on rare occasions it could be 1 or 2). That's why there's one large picturebox and all of the tiles are blitted on. Then the character is.

Anyways, IntersectRect works seeing if two RECTs are intersecting. For example:

VB Code:

Dim X As RECT: Dim Y As RECT
 
X.Left = Chara.NextX
X.Top = Chara.NextY
X.Right = Chara.NextX + Chara.Width
X.Bottom = Chara.NextY + Chara.Height
 
Y.Left = Tree.X
Y.Top = Tree.Y
Y.Right = Tree.X + Tree.Width
Y.Bottom = Tree.Y + Tree.Height
 
If Not IntersectRect(X, Y) Then
    Chara.NextY = Chara.Y
    Chara.NextX = Chara.X
End If

An ideallistc sample at best, this says you have a tree and a character, and the character & tree have X, Y, Height, and Width properties. Normal stuff. The chara also has a nextx & y, which is where you are moving them. You can simply use something like this before drawing, to make sure that the character doesn't move into said "tree".

but doesn't that mean i have to declare it for every tile on my map? is there a way i could use interesect RECT with everysingle tile (1) on my map?

It's easy, instead of a Tree, use the tile where the player is about to move to :) (for example Map(PlayerX, PlayerY-1) if he's moving up ;)
