我还有这个不错的汽车课:
local car={};
local car_mt = { __index=car };
local this;
function car.new(_x, _y)
local ncar=
{
img=display.newImageRect("test_car.png",50,120,true);
x=0;
y=0;
main_frame=function(self)
self.img.x=self.x;
self.img.y=self.y;
end
}
function ncar:set()
self.x=_x;
self.y=_y;
Runtime:addEventListener("enterFrame",self.main_frame(self));
end
ncar:set();
return setmetatable(ncar,car_mt);
end
return car;
我这样称呼它:
function scene:enterScene( event )
local group = self.view
physics.start();
local car1=pcar.new(200,200);
end
它工作正常,例如,它给了我一个错误“断言失败”
> getOrCreateTable
> addEventListener
> addEventListener
> Runtime:addEventListener("enterFrame",self.main_frame(self));
在显示器上,一切似乎都很好。怎么了?
