What is it?
Eg:
modos = pygame . display . list_modes ()
tela = pygame . display . set_mode ( modos [ 0 ] )
rect = pygame . Rect ( 0 , 0 , 10 , 10 )
pygame . display . set_caption ( " Teste do PyGame " )
while tela . get_rect (). contains ( rect ):
tela . fill ( ( 0 , 0 , 0 ) )
tela . fill ( ( 255 , 0 , 0 ) , rect )
rect . move_ip ( 10 , 10 )
pygame . display . flip ()](https://image.slidesharecdn.com/pygame-gamedevelopment-120309111717-phpapp02/85/XIX-PUG-PE-Pygame-game-development-14-320.jpg)

XIX PUG-PE - Pygame game development
- 1. Pygame - Game Development Matheus Melo XIX PUG-PE
- 2. Schedule Introduction What is PyGame? PyGame essential Elements Developing games with Pygame
- 3. What is Pygame? Set of Python modules for writing games Compatible with SDL Free
- 4. Best Features No need to OpenGL setup Multi-core C/Assembler Core Functions Portable Easy to use Comunity
- 5. Problems Python is slow But you can do something to turn this out. You write too much Isn’t a Game Engine, it’s a library.
- 6. Essential Elements Surface What is surface? 2D and 3D planes. Eg: tamanho = ( 640 , 480 ) cor = ( 255 , 0 , 0 ) # v e rme lho superficie = Surface ( tamanho ) superficie . set_at ( ( 10 , 20 ) , cor ) superficie . fill ( cor , ( 11 , 21 , 50 , 50 ) ) tela = pygame . display . set_mode ( tamanho )
- 7. Surface – Important Functions fill( color, area) Fill a area with the selected color get_at( position ) Returns the color that was in the setted position set_at( position, color) Set the color on that position
- 8. Surface – Color Depth 256 Colors 24 bpp RGB 3 Bytes per color
- 9. Surface - Transparency ColorKey One color is chosen to be transparent Image Alpha Can have his Translucency between 0 and 255 Can be used together with ColorKey Per-Pixel Alpha Has a associated Alpha component. Cannot be used with another transparency
- 10. What is Blit ? Convert the current Surface Color Depth to the next Surface Color Depth It is a very costly function What is the alternative?
- 11. Rect What is it? Eg: r = Rect ( ( 10 , 10 , 50 , 100 ) ) print r.top , r. bottom # 1 0 1 1 0 print r.left , r. right # 1 0 6 0 print r.midtop , r. midleft # ( 3 5 , 1 0 ) ( 1 0 , 6 0 ) print r. center # ( 3 5 , 6 0 ) c1 = r. collidepoint ( 30 , 40 ) c2 = r. colliderect ( ( 0 , 0 , 100 , 200 ) ) r2 = r. inflate ( 10 , 10 ) r2. move_ip ( 5 , 5 )
- 12. Rect – Important Functions clamp (area) Returns a new rectangle inside this area clip(area) Returns a new rectangle with his area cliped to fill the new area collidepoint(x, y) Check if the point is in the rectangle. colliderect(area) Check if the area toch the current rectangle
- 13. Rect – Important Functions contains(area) Check if the area is in the rectangle. inflate(x,y) Returns a new rectangle with the dimensions of the current rectangle increased according to the passed value move(x,y) Returns a new rectangle with the positions of current rectangle driven by passed values
- 14. Display What is it? Eg: modos = pygame . display . list_modes () tela = pygame . display . set_mode ( modos [ 0 ] ) rect = pygame . Rect ( 0 , 0 , 10 , 10 ) pygame . display . set_caption ( " Teste do PyGame " ) while tela . get_rect (). contains ( rect ): tela . fill ( ( 0 , 0 , 0 ) ) tela . fill ( ( 255 , 0 , 0 ) , rect ) rect . move_ip ( 10 , 10 ) pygame . display . flip ()
- 15. Display – Essential Functions flip() Update all the screen content get_surface() Return the current surface list_modes() List possible resolutions/dimensions set_caption(title) Change screen title
- 16. Display – Essential Functions set_mode(size) Setup the screen with the passed size toggle_fullscreen() Toggle to fullscreen update(rect_list) Update certain areas of the screen depending of the passed list of rectangles
- 17. Event What is it? Thereare two methods to handle the line of events Event Queued Direct consultation of devices
- 18. Event Queued from pygame . locals import * for event in pygame . event .get (): if event . type == QUIT : sys . exit () elif event . type == KEYDOWN : print event .key
- 19. Direct Consultation of Devices from pygame . locals import * while not ( pygame . mouse . get_pressed ()[ 0 ] or pygame .key . get_pressed ()[ K_SPACE ] ): pygame . event . pump ()
