当我尝试与 BCloud1.png 床发生碰撞时,我试图索引全局“BCoud1”(一个零值)?有什么简单的方法可以解决这个错误吗?
我已经这样做了:
function getRandomStar()
local temp = starTable[math.random(1, #starTable)] -- Get a random star from starTable
local randomStar = display.newImage(temp.imgpath) -- Set image path for object
if ( temp.imgpath == "BCloud1.png" ) then
temp.imgpath = "BCloud"..tostring(math.random(1, 3))..".png";
physics.addBody( BCloud1, { density=3.0, friction=0.5, bounce=0.3 } )
end
if ( temp.imgpath == "BCloud2.png" ) then
temp.imgpath = "BCloud"..tostring(math.random(1, 3))..".png";
physics.addBody( randomStar, "static", { density=.1, bounce=.1, friction=.2, radius=45 } )
end
if ( temp.imgpath == "BCloud3.png" ) then
temp.imgpath = "BCloud"..tostring(math.random(1, 3))..".png";
physics.addBody( randomStar, "static", { density=.1, bounce=.1, friction=.2, radius=45 } )
end
randomStar.myName = "star" -- Set the name of the object to star
randomStar.movementSpeed = temp.movementSpeed; -- Set how fast the object will move
randomStar.x = math.random(-30, _W);
randomStar.y = -35;
randomStar.rotation = math.random(0,20) -- Rotate the object
starMove = transition.to(randomStar, {
time=randomStar.movementSpeed,
y=500,
onComplete = function(self) self.parent:remove(self); self = nil;
end
}) -- Move the star
end--END getRandomStar()
local function onLocalCollision1( self, event )
if ( event.phase == "began" ) then
print (" Collision1 ")
elseif ( event.phase == "ended" ) then
end
end
BCloud1.collision = onLocalCollision1
BCloud1:addEventListener( "collision", BCloud1.png)
