lua - 在 Corona 中使用 setDrawMode 更改 drawMode

Question

我想在 Corona 中更改 drawMode。它仅在开始时身体倒在地上时才起作用。当身体躺在地上时，我无法更改 drawMode。有人可以帮我吗？这是带有 onKeyEvent 函数的代码。

local physics = require "physics"

function onKeyEvent( event )

if (event.keyName == "d") then
    physics.setDrawMode( "debug" );
end

if (event.keyName == "n") then
    physics.setDrawMode( "normal" );
end

if (event.keyName == "h") then
    physics.setDrawMode( "hybrid" );
end

end

Runtime:addEventListener( "key", onKeyEvent );

physics.start();
physics.setScale( 60 )
physics.setGravity( 0, 9.8 ) -- initial gravity points downwards


local groundIm = display.newRect(0, 400, 320, 20);
groundIm:setFillColor(255, 255, 255);
local ground = physics.addBody(groundIm, "static", {friction = 0.5});

local boxIm = display.newRect(100,100,30,30);
boxIm:setFillColor(0, 0, 255);

local triangleShape = { 0,-35, 37,30, -37,30 };

local body = physics.addBody(boxIm, "dynamic", {shape = triangleShape});

Answer 1

只需添加这行代码，一切都应该工作

boxIm.isSleepingAllowed = false
