Question

我想将这些发射器对象添加到组中而无需手动执行。我打算做Emitter ..我但它不是一个字符串

local function createEmitter(X,Y)
local emitter = display.newEmitter( emitterParams ) 
  emitter:scale(1.5,1.3)
  emitter.isVisible = false         
  emitter.x =X
  emitter.y =Y
  return emitter
end 

emitter_1 = createEmitter()
emitter_2 = createEmitter()
emitter_3 = createEmitter()
for i=1,3 do        
  EmitGroup:insert(emitter_1)
end

不是使用for循环将其添加到组中，而是可以将它们插入到函数本身中。

local function createEmitter(X,Y)
  local emitter = display.newEmitter( emitterParams ) 
  emitter:scale(1.5,1.3)
  emitter.isVisible = false         
  emitter.x =X
  emitter.y =Y
  EmitGroup:insert(emitter) -- Added line
 return emitter
end 

emitter_1 = createEmitter()
emitter_2 = createEmitter()
emitter_3 = createEmitter()

- 对于i = 1,3做 - EmitGroup：insert（emitter_1） --end

将显示对象插入组或表中
