So Ive been at this one problem for more than a week now and i feel like Ive tried everything. Nothing works, Ive looked it up, but at the same time I don't want to just copy code i would like to actually understand it.
def x_collision(self):
for tile in tiles:
self.rect = pygame.Rect(self.x, self.y, self.size, self.size)
if tile.colliderect(self.rect):
if self.x_vel > 0:
self.x = tile.right
if self.x_vel < 0:
self.x = tile.left - self.size
def y_collision(self):
for tile in tiles:
self.rect = pygame.Rect(self.x, self.y, self.size, self.size)
if tile.colliderect(self.rect):
if self.y_vel > 0:
self.y = tile.bottom
if self.y_vel < 0:
self.y = tile.top
This is just the two main functions for the collision located inside the player class.
Ive gotten the collisions to work on each axis but when i merge the two together it just goes insane, I'm guessing this has something to do with the position of the player being set in the wrong place but that shouldn't be the problem considering im not checking for the collision in one function but instead in two different for each the x and y.
Just, it's probably because of some stupid reason and it shouldn't be that hard if you're not dumb like me but i just can't seem to figure it out
Also if you're testing the code just delete everything that has something to do with sound!
Here is the entire code for reference (i know it's messy but im very new to this so good luck!)
