im trying to make a zelda type adventure game and need help with collision code. heres my code

Code:
Function BoundingBox(bimage,bx,by,bsubx,bsuby,bsubx2,bsuby2)
HandleImage bimage,0,0
pimagex = ImageWidth(p1\image)
pimagey = ImageHeight(p1\image)
bimagex = ImageWidth(bimage)
bimagey = ImageHeight(bimage)
 
check = 1
test = 0
testupleft = 0
 
If RectsOverlap(p1\wx-(pimagex/2),p1\wy-(pimagey/2),pimagex,pimagey,bx+bsubx,by+bsuby,bimagex-bsubx2,bimagey-bsuby2)
p1\movspeed=p1\movspeed/2
If p1\direction = LEFTMOVE Or p1\direction = RIGHTMOVE
If check = 1
p1\wx = p1\lastx
check = 0
EndIf
EndIf
If p1\direction = UPMOVE Or p1\direction = DOWNMOVE
If check = 1
p1\wy = p1\lasty
check = 0
EndIf
EndIf 
If p1\direction = UPLEFTMOVE Or p1\direction = UPRIGHTMOVE ;hits bottom
If p1\wy-(pimagey) > by+bsuby+bimagey-bsuby2
If check = 1
p1\wy = p1\lasty
check = 0
EndIf
EndIf
EndIf
If p1\direction = UPLEFTMOVE Or p1\direction = UPRIGHTMOVE ;hits side
If p1\wy-(pimagey) < by+bsuby+bimagey-bsuby2
If check = 1
p1\wx = p1\lastx
check = 0
EndIf
EndIf
EndIf
If p1\direction = DOWNLEFTMOVE Or p1\direction = DOWNRIGHTMOVE ;hits top
If p1\wy-(pimagey) > by+bsuby
If check = 1
p1\wx = p1\lastx
check = 0
EndIf
EndIf
EndIf
If p1\direction = DOWNLEFTMOVE Or p1\direction = DOWNRIGHTMOVE ;hits side
If p1\wy-(pimagey) < by+bsuby
If check = 1
p1\wy = p1\lasty
check = 0
EndIf
EndIf
EndIf
EndIf
 
End Function
-the upleft,upright etc coding is what direction the plaayer is moving regardless of strafing
-the test and testupleft were used to alert me if the coding was being triggered

its not my first attempt at this collision and its probably not the best way to do it

i want code that stops the player when it collides with any of my images and can move diagonally into the object (with some loss of speed)

any ideas?
