Collision Detection help PLZ!!!
Author
Sorry for so many questions but I am making a game and here is how I did it, First I made 2 types like this:
Public Type aMan
x As Integer
y As Integer
End Type
Public Type aWall
x As Integer
y As Integer
End Type
public Man as aMan
public Wall as aWall
Then I loaded in my pictures and displayed them on the screen
with the PaintPicture method.
What I want to do now is detect collsion between my person
and the wall
if I do this : If man.x <= wall.x then man.x = man.x - 200
it kind of works but even when I go around the wall
it stops me.
Anybody know a way I can detect just the wall and not the whole row? Thanks a lot.
This looks like you''re doing it in VB or QB, so that''s what I''ll be responding in...
First, add two things to your man and your wall: a width and a height that describes their size.
Then:
IF ( man.x + man.width >= wall.x AND_
man.x <= wall.x + wall.width AND_
man.y + man.height >= wall.y AND_
man.y <= wall.y + wall.height )
THEN
collision = true;
( the _ in the code denotes a continuation to the next line...
if you''re doing this in QB, you''ll have to put it all on
the same line, but I THINK that will work in VB ).
This will test the "bounding boxes" to see if they collide.
Once you know if there''s a collision, you can determine which direction the collision is taking place in and prevent the character from moving any further in that direction.
It may not be the best way, but it should work. :-D
