2D 游戏的障碍路径检测
我主要致力于平台游戏的开发，并且仍处于起步阶段，所以我对最佳实践/算法感到好奇。我的背景中只有一座城堡，底部大约 200 像素高，有一些草，稍微上下弯曲。在中间（这是背景 png 的一部分）我有一个圆角矩形岩石。所以没有什么是它自己独立的对象，只有角色和背景。
目前，我将角色的路径设置为初始化颜色数组并加载路径坐标字典。我这样做的方法是遍历 x 轴上的每个像素并向下（就像 (0,1), (0,2)...然后 (1,0), (1,1).. .)。当我发现第一个接近绿色的 RGB 值时，我将前面的 y 值存储到路径坐标字典中。因此，pathDictionary[0]=>563 的值将是草，而 562 将是草或路径上方的黑色。
对于中间的岩石，我只是有一个条件，即查看我的 x 坐标是否超出某个点，以及 y 坐标减去角色原点是否大于指示角色在背景。这显然不是我到处使用的方法，但我想知道是否有更有效的方法？也许查看 png，获取岩石的坐标并创建一个矩形？
根据你们的建议，跳到这块背景岩石上的最佳方式是什么？
I'm pretty much working on a platformer and still starting out so I was curious about best practices/algorithms. I have in my background just a castle and about 200px high at the bottom some grass which slightly curves up and down. In the middle (which is part of the background png) I have a rounded rectangle rock. So nothing is its own seperate object, just the character and the background.
Currently, I set up the path my character goes as initializing an array of colors and loading up a path coordinate dictionary. The way I do it is I go through each pixel on the x-axis and go down (so like (0,1), (0,2)... then (1,0), (1,1)...). The first instance I find of a RGB value of near green, I store the preceeding y value into the path coordinate dictionary. So a value of pathDictionary[0]=>563 would be the grass while 562 would be the black above the grass or the path.
For the rock in the middle, I simply have a condition where I see if my x-coordinate is beyond a certain point and if the y-coordinate minus the origin of my character is greater than a value indicating that the character met the rock in the background. This is obviously not an approach I'd use everywhere but I'm wondering if there is a more efficient way? Perhaps looking at the png, getting the coordinates of the rock and creating a rectangle?
Based on what you guys recommend, what would be the best way for jumping onto this background rock?

最近向我介绍了音速物理指南，它是从《刺猬索尼克》系列中逆向设计的信息游戏。它可能有很多对您的任务有用的信息。
I was recently introduced to the Sonic Physics Guide which is information reverse engineered out of the Sonic the Hedgehog series of games. It may have a lot of useful information for your quest.
