CoronaSDK DisplayObject Summary （2511 API）

著名跨平台手游引擎Corona SDK的Display对象创建方式汇总:

第一部分：分组类
Group:
display.newGroup()

Container:
display.newContainer( [parent, ] width, height )

第二部分：图像类
ImageSheet:(图像列表)

graphics.newImageSheet( filename, [baseDir, ] options )     

a 简单模式：
local option ={ width = 50, height = 50, numFrames = 2, border = 0, sheetContentWidth = 100, sheetContentHeight = 50}

b 复杂模式：
local option = {
    frames = { {x = 100, y = 100, width = 100, height = 100,}, { ...}, {...}),
    border = 0, sheetContentWidth = 100, sheetContentHeight = 50
}

ImageRect:(zoomStrech)
display.newImageRect( [parentGroup,] filename, [baseDir,] width, height )
display.newImageRect( [parentGroup,] imageSheet, frameIndex, width, height )

Sprite:
display.newSprite( imageSheet, sequenceData )
display.newSprite( parent, imageSheet, sequenceData )

imageSheet可以用graphics.newImageSheet来创建。
sequenceData：
 单序列（连续帧）

-- Example assumes 'imageSheet' is already created from graphics.newImageSheet()

-- consecutive frames
local sequenceData =
{
    name="walking",
    start=3,
    count=6,
    time=100,
    loopCount = 0,   -- Optional ; default is 0 (loop indefinitely)
    loopDirection = "bounce"    -- Optional ; values include "forward" or "bounce"
}

local character = display.newSprite( imageSheet, sequenceData )

  单序列（不连续帧）

-- Example assumes 'imageSheet' is already created using graphics.newImageSheet()

-- non-consecutive frames
local sequenceData =
{
    name="walking",
    frames= { 3, 4, 5, 6, 7, 8 }, -- frame indexes of animation, in image sheet
    time = 240,
    loopCount = 0        -- Optional ; default is 0
}

local character = display.newSprite( imageSheet, sequenceData )

  多序列

-- Example assumes 'imageSheet' already created using graphics.newImageSheet()

local sequenceData =
{
    { name="walking", start=1, count=3 },
    { name="running", frames={ 3, 4, 5, 6, 7, 8 }, time=120, loopCount=4 },
    { name="jumping", start=9, count=13, time=300 }
}

local character = display.newSprite( imageSheet, sequenceData )

    多ImageSheet

-- 1st image sheet
local sheetData1 = { width=64, height=64, numFrames=6, sheetContentWidth=384, sheetContentHeight=64 }
local sheet1 = graphics.newImageSheet( "mySheet1.png", sheetData1 )

-- 2nd image sheet
local sheetData2 = { width=64, height=64, numFrames=6, sheetContentWidth=384, sheetContentHeight=64 }
local sheet2 = graphics.newImageSheet( "mySheet2.png", sheetData2 )

-- In your sequences, add the parameter 'sheet=', referencing which image sheet the sequence should use
local sequenceData = {
                { name="seq1", sheet=sheet1, start=1, count=6, time=220, loopCount=0 },
                { name="seq2", sheet=sheet2, start=1, count=6, time=220, loopCount=0 }
                }

local myAnimation = display.newSprite( sheet1, sequenceData )
myAnimation.x = display.contentWidth/2 ; myAnimation.y = display.contentHeight/2
myAnimation:play()

-- After a short time, swap the sequence to 'seq2' which uses the second image sheet
local function swapSheet()
        myAnimation:setSequence( "seq2" )
        myAnimation:play()
end
timer.performWithDelay( 2000, swapSheet )

第三部分：形状类
Text:
display.newText( options )          -- option field: parent, text, x, y, width, height, font, fontsize, align

display.newText( [parentGroup,] text, x, y, font, fontSize )
display.newText( [parentGroup,] text, x, y, [width, height,] font, fontSize )

Rect：
display.newRect( x, y, width, height )
display.newRect( parent, x, y, width, height )

Circle：
display.newCircle( xCenter, yCenter, radius )
display.newCircle( parent, xCenter, yCenter, radius )

RounderRect:
display.newRoundedRect( x, y, width, height, cornerRadius )
display.newRoundedRect( parent, x, y, width, height, cornerRadius )

Line:
display.newLine( [parentGroup,] x1, y1, x2, y2 [, x3, y3, ... ] )

Polygon:
display.newPolygon( x, y, vertices )
display.newPolygon( parent, x, y, vertices )

local vertices = { 0,-110, 27,-35, 105,-35, 43,16, 65,90, 0,45, -65,90, -43,15, -105,-35, -27,-35, }
