如何在corona sdk中进行颜色转换。
我试过了,但没用
transition.to (show_text, {time=1000,color="rgb(0,0,0)"});
最佳答案
以下技巧有效。不幸的是,如果不使用多个过渡,它不允许非常复杂的颜色操作:
local function modify(text)
local mt = {
r = 0,
g = 0,
b = 0,
__index = function(t, k)
if k == "r" or k == "g" or k == "b" then
return getmetatable(t)[k]
end
end,
__newindex = function(t, k, v)
getmetatable(t)[k] = v
if k == "r" or k == "g" or k == "b" then
t:setTextColor(math.round(t.r or 0), math.round(t.g or 0), math.round(t.b or 0))
end
end
}
local originalSetTextColor = text.setTextColor
text.setTextColor = function(self,r,g,b)
mt.r = r
mt.g = g
mt.b = b
originalSetTextColor(self, r,g,b)
end
setmetatable(text, mt)
end
local show_text = display.newEmbossedText("I am the very model of a modern major general", display.screenOriginX,0, native.systemFont, 30);
modify(show_text)
show_text:setTextColor(255,0,255)
transition.to (show_text, {time=1000,r=0,})
transition.to (show_text, {time=1000,g=255})
transition.to (show_text, {time=1000,b=0})
