Collisions in Pygame - Beginner Tutorial

[@HoRRoRlets]

My Dude. I have been playing with pygame for months now. Got number of projects under my belt. I always find myself coming back to your vids for some assistance...This here, is a perfect example. Been looking for a means of determining line collisions...and lo and behold ... Russ has done it again!! Much appreciated man!!

[@sushismitcher225]

I have needed line collisions for a project over a year ago with pygame. I've been looking for simple line collisions since. This is a deus ex machina for my project! Russ just got a new subscriber.

[@Blinkers2007GameDev]

Hi, I need help with something. I have made a Space Invaders game with rect collision. The enemies and the player are not rect objects. I noticed a problem with the game: The collision ONLY works if I hit the enemies on the right corners. I am using distance as my collision but colliderrect-based collision does not work either. Is it supposed to be like that with non-rectangle objects or have I done something wrong? Thank you for your answer!

[@dibosh7405]

How can I tweak the position of the hitbox rectangle relative to whatever model/ sprite I'm using? Can I do that within the library or?

[@CodingWithRuss]

Yes, you can manually create a rectangle with pygame.Rect() and pass in the size you would like to use. Then you can draw your image using the rectangle's x and y coordinates. You may just need to offset it a little bit if it doesn't look right.

[@dibosh7405]

@@CodingWithRuss Thank you. I think I get the gist. Any chance you could do a video on this, just in case? I'll play around with it until then. Cheers 😄

[@albin197]

for some reason the "rect_1 = pygame.Rect(0, 0, 25, 25)" is giving me "'module' object is not callable" error

[@MoiLpoi]

It's pygame.rect..Rect

[@MoiLpoi]

It's pygame.rect.Rect(a,b,c,d)

[@TomatoNotTomato]

You need to used double brackets (())

Welp too late

No problem :)

guy thanks because I made it if the box1 touch's box2 it make just basically a makeshift edge grip

[@yourboizach9681]

I get collisions but I don't understand how to exactly handle them once they happen. I have a little space invaders game but instead of ships you shoot space rocks or they hit you and you die, but my ship can shoot, once a collision is detected I need to know how I can make that rock dissapear, I am currently just moving the rock back to the top so it looks like you just blow it up but I will need to actually just remove the rock from the game, how can I do this?

[@witherhoard99]

@yourboizach9681 I'm assuming you have all of your rocks in a list. I'm also assuming have a method to somehow check if the rock got hit. Use a for loop. Here is some example code. for star in stars[:]: if star.got_hit_by_bullet: stars.remove(star)

[@yourboizach9681]

@@witherhoard99 i figured it out, I needed to use .kill() It's a sprite group so you can't use .remove or .clear I don't think My game has actually advanced significantly since this post, I wish I could link it here somehow.

[@alvarohernandez2764]

Why define all the colors as RGBs instead of just use the abailable color presets as string? For example WHITE = (225, 225, 225) pygame.draw.rect(screen, WHITE, obstacle) #instead of pygame.draw.rect(screen, "white", obstacle)

[@CodingWithRuss]

Both are valid and in some of my games I use the named colour presets. If you want to define your own colours though that aren't part of the defined list, it would make sense to create a variable so it could be reused in other parts of the game
