事件偵聽器從外部模塊調用函數

調用一個函數，但我在下面說調用函數的代碼收到錯誤信息。已收到的CONSOLE

ROCKETCLASS.LUA

module(..., package.seeall) 

function rocket() 

local rocket = {} 
local rocket_mt = { __index = rocket } -- metatable 
local sprite 
local rockettop, rocketbottom, speedX, speedY 


function rocket.new() -- constructor 

local newRocket = { 
sprite = "red-rocket.png" 

} 
return setmetatable(newRocket, rocket_mt) 
end 

function rocket:draw(x,y,group) 

local spritesheetdata = { 
width = 30, 
height = 55, 
numFrames = 7, 
sheetContentWidth = 210, 
sheetContentHeight = 55, 
} 


local spritesheet = graphics.newImageSheet("red_rocket.png", spritesheetdata) 



local spritesequencedata = { 

{ name = "idle", frames = {1}, 
    } , 

{ name = "afterburn", 
    start = 2, 
    count = 2, 
    time = 500, 
    loopCount = 0, -- optional default 0(infinite) 
    loopDirection = "forward" -- optional (default) 
    } , 
    { name = "explode", 
    start = 4, 
    count = 4, 
    time = 1200, 
    loopCount = 1 
    } 
} 

    sprite = display.newSprite(spritesheet, spritesequencedata) 
    rockettop = {-14.5, 5, 0, -25,14.5,5} 
    rocketbottom = {-14.5,7,-14.5,6,14.5,6,14.5,7} 


    physics.addBody(sprite, {shape = rockettop},{bounce = 0.5,friction = 0.6, shape = rocketbottom}) 
    sprite.angularDamping = 2 
    sprite.x = x 
    sprite.y = y 
    sprite:setSequence("idle") 
    sprite:play() 
    group:insert (sprite) 

    end 

function rocket:thrust(event) 

speedX = 0.0025 * (math.sin(sprite.rotation*(math.pi/180))) 
speedY = -0.0025 * (math.cos(sprite.rotation*(math.pi/180))) 
if(event.phase =="began") then 

    sprite:applyLinearImpulse(speedX, speedY, sprite.x, sprite.y) 

    return true 
    end 
    sprite:setSequence("afterburn") 
    sprite:play() 

end 

    return rocket 


end

和CONTROLS.LUA

module(..., package.seeall) 
rocket = require("rocketclass") 



local controlthrust = display.newImage("thrust control.png") 
controlthrust.y = display.contentWidth/1.6 
controlthrust.x = display.contentWidth/1.1 


local controlleft = display.newImage("direction controls.png") 
controlleft.y = display.contentWidth/1.6 

local controlright = display.newImage("direction controls.png") 
controlright.y = display.contentWidth/1.6 
controlright.x = display.contentWidth/6 
controlright.rotation = 180 



controlthrust:addEventListener("touch",rocket:thrust)

錯誤是：

controls.lua：21：試圖調用方法 '推力' 堆回溯： C：功能'錯誤' ？：功能'gotoScene' ... nts \ corona項目\火箭着陸器 - 類\ menu.lu

我沒有看到你在哪裏調用rocket.new（）。我想你會需要做這樣的事情：

rocketclass = require("rocketclass") 

rocket = rocketclass.new()

之前，你設置它的觸摸處理程序。

感謝您的回覆，我在level1.lua（未顯示）中做到了這一點，但是我已經通過重新創建火箭類和刪除已棄用的方法模塊（...，package.seeall）來修復問題我現在可以完全控制我的火箭和所有三個lua文件正在互動，如果你想看，請讓我知道 – Krisdom
