hey guys,
i watched a tutorial on dragging physics. well im wanting to get the cursor i have to be draggable. the one in the video uses the sample dragMe which is the roundedrect, but im using an image. any ideas? thanks in advance!

[code]
module(…, package.seeall)
local localGroup
function new()
localGroup = display.newGroup()
print( “Level 1” )

local sky = display.newImage( “Turqouise Back.png”, 0, 0 )
localGroup:insert(sky)

local button = display.newImage( “Main Menu.png” )
local function buttont ( event )
media.playEventSound( “Robot Blip.caf” )
if event.phase == “ended” then
director:changeScene(“Menu”,“moveFromLeft”)
end
end
button:addEventListener(“touch”,buttont)
button.x = 260
button.y = 34
localGroup:insert(button)

local cursor = display.newImage( “triangle.png”, 120, 450 )
localGroup:insert(cursor)

i added the code to start the physics engine, but still can’t figure it out. any help would be greatly appreciated! [import]uid: 19836 topic_id: 7520 reply_id: 26798[/import]

I am not an expert on this. Prior issues I replaced newImage with new ImageRect. Worked wonders for me. Try it? [import]uid: 8576 topic_id: 7520 reply_id: 26918[/import]

i added a few more lines of code, but it still doesn’t work. any ideas?

[code]
local physics = require(“physics”)
physics.start()
physics.setGravity(0, 0)
–delete setdrawmode when done with adding all the physics…
physics.setDrawMode(“hybrid”)

module(…, package.seeall)
local localGroup
function new()
localGroup = display.newGroup()
print( “Level 1” )

local sky = display.newImage( “Turqouise Back.png”, 0, 0 )
localGroup:insert(sky)

local button = display.newImage( “Main Menu.png” )
local function buttont ( event )
media.playEventSound( “Robot Blip.caf” )
if event.phase == “ended” then
director:changeScene(“Menu”,“moveFromLeft”)
end
end
button:addEventListener(“touch”,buttont)
button.x = 260
button.y = 34
localGroup:insert(button)

local triangle = display.newImage( “triangle.png” )
object:setDrag
myImage:setDrag{ drag=true, limitX=false, limitY=false, onPress=myPressFunction,onDrag=myDragFunction, onRelease=myReleaseFunction, bounds={ 10, 10, 200, 50 })

localGroup:insert(triangle)

please anything? [import]uid: 19836 topic_id: 7520 reply_id: 27877[/import]

#9

I am not sure if the setDrag applies to images? If I follow the documentation correctly it does not (applies to movieClip)?

Also Your code should not read object:setDrag but triangle:setDrag. [import]uid: 8576 topic_id: 7520 reply_id: 27885[/import]

onPress=myPressFunction,
onDrag=myDragFunction,
onRelease=myReleaseFunction,
