I'm attempting to create a boundary around the window to stop the sprites of my game from escaping but it doesn't seem to be work, when they hit the area where its supposed to stop them it instead does nothing and sends it into 0,0 not allowing it too move.
def leavingWindow(Xpos, Ypos):#boundry, keeps sprites in the window
if Xpos<=0:
return True
elif Xpos>=950:
return True
if Ypos<=0:
return True
elif Ypos>=750:
return True
def Boundry(Xpos, Ypos):
if Xpos<=0:
Xmovement=0
elif Xpos>=950:
Xmovement=950
else:
Xmovement=+0
if Ypos<=0:
ymovement=0
elif Ypos>=750:
ymovement=60
else:
ymovement=+0
return Xmovement, ymovement
if len(preys) > 0:
for wolf in Wolf_group:
movementx, movementy = Track(wolf.x, preys[0].x, wolf.y, preys[0].y)#how the predators move
Leaving=leavingWindow(wolf.x,wolf.y)
if Leaving == True:
movementx,movementy=Boundry(wolf.x,wolf.y)
wolf.move(0,1)#movementx, #movementy)
Ive attempted changing around the code but it keeps doing this.
