Now of course, since Pygame uses Python, no body is going to use it, let alone this library. However I did spent a lot of time writing the docs<\/a> for this project.<\/p>\n Enough words! Lets see what it can do!<\/p>\n Painless relative loading<\/strong><\/p>\n Games load stuff. Images, sound, levels\u2026 And its pretty common to load a file relative to the executable or script. How do you do it in Pygame normally?<\/p>\n (Getting the path of the script, and then use os.path.join to join together path names. Loading from \u201c.\/\u201d wouldn\u2019t always work since its relative to the current working directory)<\/p>\n Its fairly easy to read and understand, but its long and kind of messy.<\/p>\n Enter the ImageLoader class<\/p>\n It would be a pretty boring helper class if that\u2019s all it can do. ImageLoader is also capable of\u00a0 other things outline here<\/a>. Loading all images in a folder, loading a sequence of images and giving back a path string relative to the origin if you don\u2019t want to load an image.<\/p>\n Collision powered level manager<\/strong><\/p>\n One approach of managing a map in games is using collision, the player can move around, as long as he\/she is not colliding with the level. Its intuitive and powerful. Rapid Pygame provides a way of quickly getting a level up and running.<\/p>\n This will produce a level that a player can move around in (left right and jump). The level manager will take care of gravity, player movement and level collision. Pretty simple right? A 60 line basic game :). This will become even shorter and simpler in future version of the library. The details about the level format and the player class can all be found in the docs<\/a>.<\/p>\n Behind the scenes<\/strong><\/p>\n That\u2019s pretty much all the features of the library, other than the\u00a0pre-made Player class that renders animation for you.\u00a0 Below is a bit about how the level manager behind the scenes.<\/p>\n One thing the level manger do is take the level landscape, and break it down into rectangles, which are then used for collision checking with the player. I\u2019ve made some improvement to the algorithm compare to the old ones I used in the past. Each block represents a rectangle<\/p>\n The old approach is to break the level down into strips either vertically or horizontally.<\/p>\n The algorithm in the library will try to maximize the area of the rectangles, producing fewer rectangles for faster collision checking<\/p>\n Although its not prefect<\/p>\n Both methods are probably fast enough to not have a real impact on the game\u2019s performance, but its nice to know that the algorithm that powers the manager is semi-smart XD<\/p>\n \u00a0<\/p>\n Well, hopefully I didn\u2019t just waste my time typing this up, even though I highly doubt it. Thanks for reading and good luck to everyone in your future LD endeavors!
