Python Pygame Draw Pixel
From pygame import gfxdraw gfxdraw.pixel(surface, x, y, color) Do note, however, the warning: EXPERIMENTAL!: meaning this api may change, or dissapear in later pygame releases. Python Programming tutorials from beginner to advanced on a massive variety of topics. But, in general, the most likely-to-cause-a-hangup-process is actually updating pixel values on the screen. Thus, generally, the process for a simple game is something like: run game logic/calcs, 'draw' the next frame in the background without actually. Per-pixel read/write performance in Pygame. TIGSource has an official Discord server now! (written with python+pygame)- for example that makes the screen become black and white. Getting and setting pixels one at a time is generally too slow to be used in a game or realtime situation. It is better. The following are 50 code examples for showing how to use pygame.gfxdraw().They are extracted from open source Python projects. You can vote up the examples you like or vote down the exmaples you don't like. A pixel draw is a single array write on an array that fits entirely in the last-level cache. I don't know how pygame implements it, but regardless of how it's done, the vast majority of the cost of drawing a single pixel will be in the overhead of the python function call. Step 003 - Surfaces and Drawing. In the first code line, a pygame surface is created with the dimensions 50 pixel width (x-axis) and 50 pixel height (y-axis). This little pygame surface is named ball. Use python's range function to draw a pretty pattern across the screen. Start with this code and expand to all 4 corners. S = pygame.image.load('spam.png') s.convert_alpha() The documentation of the pygame.image module says that applying convert_alpha is necessary for PNGs with transparency. If you want you can modify the alpha value of each pixel with the modules draw and surfarray. When specifying a color, use then a tuple of four integers: (red, green, blue.

Clavat and a racial Selkie. I guess the first step in resolving this issue is to clarify what the desired behaviour is. For example: Should the polygon ([0, 0], [3, 0], [3, 3], [0, 3]) really be a 4x4 square or should it be 3x3 ? IMHO it should be 3x3 which would be analogue to how C for-loops or python ranges handle their bounds and the same arguments apply. Mainly, that two polygons sharing an edge should not overlap. Any opinions? |

Original comment byJason Marshall (Bitbucket: jmm0, GitHub: jmm0): If I were designing pygame.draw.polygon, I would make it fill in every point that I pass to it when the width argument is 0. This is what pygame.draw.polygon does when the width argument is 1. So, I would expect the polygon ([0, 0], [3, 0], [3, 3], [0, 3]) to always be 4x4. (The analogy with C for-loops and Python ranges stops making sense to me when I consider polygons that aren't rectangular.) However, it is much more important that it draw consistently in both the x direction and the y direction. Whether that polygon is 3x3 or 4x4 is just a personal preference. pygame.gfxdraw.filled_polygon draws in the same way as pygame.draw.polygon (with a width argument of 0). I made the following little script to play with the polygon functions. It may be useful to somebody. |
