Transition.to 在 Corona SDK 中不能正确地移动对象

我有一个包含敌人的表格，只是想让它们通过 gameLoop 沿着屏幕移动，但由于某种原因似乎什么也不起作用。这可能是一个简单的修复，但我已经努力修复它却一无所获。有人知道怎么回事吗？

gameLoop 函数

local i
 for i = 1, #enemies do--.numChildren,1, -1 do
    local blocks = enemies[i]
    if blocks ~= nil and blocks.x ~= nil then
        enemyRate = 2.0 + (0.1 * wave)
        transition.to( blocks, { time=1500, x=300} )
    end
 end

生成函数

function spawnEnemy()

local spawnData = { -- 将生成存储在表格中，以便稍后更轻松地添加新的敌人

{name = "Blue", seq = "blueRect", frame = 3, imgSheet = imageSheetRectangle, seqData = sequenceDataRectangle},
{name = "Red", seq = "blueCross", frame = 1, imgSheet = imageSheetCross, seqData = sequenceDataCross},
{name = "Green", seq = "blueCirc", frame = 2, imgSheet = imageSheetCircle, seqData = sequenceDataCircle}
}

local xPos = display.contentWidth - 150
local r = math.random(1, #spawnData)

local sd = spawnData[r] -- 获取此敌人的生成数据

local s = display.newSprite(sd.imgSheet, sd.seqData)
s.name = sd.name
physics.addBody(s, { isSensor = true })
s:setSequence(sd.seq)
s:setFrame(sd.frame)
s.y = display.contentHeight - 400
s.x = xPos
enemies[#enemies+1] = s
enemyGroup:insert(s)
