lua - 添加 '' physics.addBody''本地imgpath lua

Question

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

============================================= =============================

我想将 physics.addBody 添加到 cloud4 以便它可以与 Runtime:addEventListener("collision", onCollision) 但如果我这样做:

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);

我收到一个错误的参数错误，我该如何解决？

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()

线

physics.addBody(cloud4, "static", {densit=.1, bounce=0.1, friction=.2, radius=45})

里面有错别字，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 } )
