添加'';物理学.addBody'';本地imgpath lua
通过添加解决添加'';物理学.addBody'';本地imgpath lua,lua,coronasdk,corona-storyboard,Lua,Coronasdk,Corona Storyboard,通过添加解决 if ( temp.imgpath == "badcloud.png" ) then physics.addBody( randomcloud, "static", { density=.1, bounce=.1, friction=.2, radius=45 } ) end ============================================================================ 我想向cloud4添加一个physics.add

我想向cloud4添加一个physics.addBody
,这样它就可以与运行时进行交互:addEventListener(“碰撞”,onCollision)
,但是如果我这样做:
local cloud4 = {}
physics.addBody(cloud4, "static", {densit=.1, bounce=0.1, friction=.2, radius=45})
cloud4.imgpath = "badcloud.png";
cloud4.movementSpeed = 18000;
table.insert(cloudTable, cloud4);
如果参数错误,如何解决
function initcloud()
local cloud1 = {}
cloud1.imgpath = "cloud1.png"; --Set Image Path for cloud
cloud1.movementSpeed = 10000; --Determines the movement speed of cloud
table.insert(cloudTable, cloud1); --Insert cloud into cloudTable
local cloud2 = {}
cloud2.imgpath = "cloud2.png";
cloud2.movementSpeed = 12000;
table.insert(cloudTable, cloud2);
local cloud3 = {}
cloud3.imgpath = "cloud3.png";
cloud3.movementSpeed = 14000;
table.insert(cloudTable, cloud3);
local cloud4 = {}
cloud4.imgpath = "badcloud.png";
cloud4.movementSpeed = 18000;
table.insert(cloudTable, cloud4);
local cloud5 = {}
cloud5.imgpath = "cloud5.png";
cloud5.movementSpeed = 21000;
table.insert(cloudTable, cloud5);
end --END initcloud()

function cloudtGame()
cloudTimer1 = timer.performWithDelay(3000,getRandomcloud, 5)
cloudTimer2 = timer.performWithDelay(2000,getRandomcloud, 0)
cloudTimer3 = timer.performWithDelay(2400,getRandomcloud, 0)
cloudTimer4 = timer.performWithDelay(7000,getRandomcloud, 0)

线路
physics.addBody(cloud4, "static", {densit=.1, bounce=0.1, friction=.2, radius=45})
有一个打字错误,导致错误。它应该是density
,而不是densit
。像这样:
physics.addBody( cloud4, "static", { density = .1, bounce = 0.1, friction = .2, radius = 45 } )
通过添加
if ( temp.imgpath == "badcloud.png" ) then
physics.addBody( randomcloud, "static", { density=.1, bounce=.1, friction=.2, radius=45 } )
end
“addBody”的错误参数#-1对象不需要
x
和y
值吗?将cloud4.x=0
和cloud4.y=0
添加到physics.addBody()调用之前。x和y值基于:函数getRandomcloud()。randomcloud.x=数学随机(10,W);y=-35;您在哪里调用了它?@kevinver您在调用addBody之前,可以指定它的x
和y
值。。
