I’m hoping there’s a good solution I’m missing, but I could sure use some help. In it’s simplest form I have 2 images in a group. I’d like the user to be able to move that group, much like a table in the “Coffee demo” where it eases out when the user releases. Hopefully very simple.
Here’s what I have so far and it works fine. But I don’t have the easing anywhere. Just not sure what to do. Any help would be appreciated.
–this allows for the user to touch and move the “director group”.
[code]
module(…, package.seeall)
local director = require “director”
local ui = require(“ui”)
local localGroup
local directorGroup = display.newGroup()
–directorGroup:setReferencePoint(display.TopCenterReferencePoint);
directorGroup.x, directorGroup.y = centerX, 50
local centerX = display.contentCenterX
local centerY = display.contentCenterY
local makeButtons = function ()
–everything in here
localGroup:insert(directorGroup)
– A basic function for dragging physics objects ••COPIED/Adapted FROM DRAGPLATFORMS TUTORIAL••
local function startDrag( event )
local t = event.target
local phase = event.phase
if “began” == phase then
display.getCurrentStage():setFocus( t )
t.isFocus = true
– Store initial position
t.x0 = event.x - t.x
t.y0 = event.y - t.y
– Make body type temporarily “kinematic” (to avoid gravitional forces)
event.target.bodyType = “kinematic”
– Stop current motion, if any
event.target:setLinearVelocity( 0, 0 )
event.target.angularVelocity = 0
elseif t.isFocus then
if “moved” == phase then
t.x = event.x - t.x0
t.y = event.y - t.y0
elseif “ended” == phase or “cancelled” == phase then
display.getCurrentStage():setFocus( nil )
t.isFocus = false
– Switch body type back to “dynamic”, unless we’ve marked this sprite as a platform
if ( not event.target.isPlatform ) then
event.target.bodyType = “dynamic”
end
end
end
– Stop further propagation of touch event!
return true
end
local CorinBG=display.newImageRect( “K_Corin_bg1.png”, 496, 476 )
CorinBG.alpha = 1
CorinBG.x, CorinBG.y=centerX, centerY
CorinBG.xScale, CorinBG.yScale = 1,1
directorGroup:insert(CorinBG)
local CorinBG2=display.newImageRect( “K_Corin_bg2.png”, 496, 375 )
CorinBG2.alpha = 1
CorinBG2.x, CorinBG2.y=centerX, 585
CorinBG2.xScale, CorinBG2.yScale = 1,1
directorGroup:insert(CorinBG2)
