Question

我曾试图用Corota SDK(使用Lua)书写习惯。关键似乎是这些“生计者”,但我也试图让他们与班级合作。现在,我们就建立了这一类“世界”。我试图在我的“标准”职能中增加一个活动——但验尸告诉我,我可以这样做。

function World:tick()
--player:tick()
--camera:tick(player.x,player.y)
--for i=0,monsters.length do
--      monster[i]:tick()
    if(rwalk) then
        mainGroup.x = mainGroup.x-10
    elseif(lwalk) then
        mainGroup.x = mainGroup.x+10
    end
end
Runtime:addEventListener("enterFrame",tick)

Error: Runtime error: assertion failed! stack traceback: [C]: ? [C]: in function assert ?: in function getOrCreateTable ?: in function addEventListener ?: in function addEventListener C:UsersEvanDesktoplua est gamemain.lua:337: in main chunk

Answer 1

This works for me. Should work for you:

World = {}

function World:tick()
    print "Hello!"
end

display.setStatusBar(display.HiddenStatusBar)
Runtime:addEventListener("enterFrame", World.tick)

All you were missing was to specify the function using World.tick instead of tick.
