I'm making a game and I need to blit my objects inside the area of a specific image. I don't want to need my surface to blit these images. Is it possible? (I'm using pygame)
It would be better in the future if you would explain what you are trying to do a bit better since it would give you more answers :)
From what I have understood you want to blit an image onto another image:
For this code to work the following premises are set:
I have written the following piece of code which you can run if you follow the above premises:
import pygame
screen = pygame.display.set_mode([800, 800], 0, 32)
#initiates screen
image1 = pygame.image.load('testimage0.jpg')
#testimage0.jpg is loaded into the variable image1
image2 = pygame.image.load('testimage.png').convert_alpha()
#testimage.png is loaded into the variable image2
while True:
screen.fill([0, 0, 0])
#screen is filled with a black background
screen.blit(image1, [200, 200])
#here image1 is blitted onto screen at the coordinates (200,200)
image1.blit(image2, [0, 0])
#here image2 is blitted onto image1 at the coordinates (0,0) which starts at the upper left of image1
pygame.display.update()
#updates display, which you can just ignore
Images are just surfaces with a sprite or picture on. The coordinate system of a surface always starts at the upper left (0,0), which is why (0,0) of image1 isn't the same as the (0,0) of screen.
I took a picture of the program and edited some arrows in to explain my point:
Hope this was a help and remember to accept as the answer if you find it acceptable.
