我正在尝试制作一个简单的平台游戏,显然我需要瓷砖碰撞。到目前为止我的代码的问题是它首先移动角色,然后检查它是否与某物发生碰撞,但有时它认为它在错误的时间发生碰撞,这取决于我是否先检查 x 轴是否发生碰撞或首先是 y 轴。我会以错误的方式解决这个问题吗?这是一些代码。
function checkCollision(val, axis, oldPos)
if axis == "x" and char.tX then
local tileX = math.ceil(val/absoluteTileSize)
local tileY = math.floor(oldPos/absoluteTileSize)
local tl, tr, bl ,br = getTouchingTiles(tileX, tileY)
local isOnFlatSurface = math.abs(oldPos/absoluteTileSize-tileY) <= .00001--might not be a good i
if isOnFlatSurface then
if tr.canCollide then
char.tX = nil
char.x = tileX * absoluteTileSize - absoluteTileSize
end
else
if br.canCollide then
char.tX = nil
char.x = tileX * absoluteTileSize - absoluteTileSize
end
end
elseif axis == "y" then
local tileX = math.ceil(oldPos/absoluteTileSize)
local tileY = math.floor(val/absoluteTileSize)
local tl, tr, bl ,br = getTouchingTiles(tileX, tileY)
if bl.canCollide or br.canCollide then
char.tY = nil
char.y = tileY * absoluteTileSize --// - absoluteTileSize
--/////////////idk why i don't need to subtract that but it works
elseif not char.tY then--start falling if walk off something
char.tY = love.timer.getTime()
char.yi = char.y
char.vyi = 0
end
end
end
