Hello everyone, i am a new user of corona sdk, and i am making a slider menu, but i am not able to make this part:
- When i touch on the slider image, it will change to other scene.
Can you give me some help?or tell me what is wrong on my code?
Code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 | module(..., package.seeall) -- vars local local main_sprt = nil local bck_shp = nil local slider = nil local slider_sprt = nil ---------------------------------------------------------------------------------------------------- -- init ---------------------------------------------------------------------------------------------------- local function init() -- statusBar display.setStatusBar( display.HiddenStatusBar ) -- main_sprt main_sprt = display.newGroup() --Screen _W = display.contentWidth; _H = display.contentHeight; -- bck bck_shp = display.newRect( 0, 0,_W,_H) main_sprt:insert( bck_shp ) bck_shp:setFillColor( 192, 192, 192 ) -- slider slider = require( "slider" ) slider:init() slider_sprt = slider:getSprite() main_sprt:insert( slider_sprt ) slider_sprt.x = 0.5 * ( _W - 256 - 16 ) slider_sprt.y = 65 local slide_sprt = nil -- slide 1 slide_sprt = renderSlide( ) slider.addSlide( slide_sprt) -- slide 2 slide_sprt = renderSlide2( ) slider.addSlide( slide_sprt ) end ---------------------------------------------------------------------------------------------------- -- Background, Slider, Text ---------------------------------------------------------------------------------------------------- function renderSlide() -- slide_sprt local slide_sprt = display.newGroup() -- go to levels local bck_sprt = display.newImageRect( "assets/slide_bck.png", 200, 200 ) bck_sprt.x = _W/2 -25; bck_sprt.y = _H/2 -100 bck_sprt.scene = "ola" function changeScene(e) if (e.phase == "ended") then director:changeScene(e.target.scene) end end slide_sprt:insert( bck_sprt ) bck_sprt:addEventListener("touch",changeScene) return slide_sprt end ---------------------------------------------------------------------------------------------------- -- Background, Slider, Text ---------------------------------------------------------------------------------------------------- function renderSlide2() -- slide_sprt local slide_sprt = display.newGroup() -- go to levels local bck_sprt = display.newImageRect( "assets/game_bck.png", 200, 200 ) bck_sprt.x = _W/2 -25; bck_sprt.y = _H/2 -100 bck_sprt.scene = "game" function changeScene(e) if (e.phase == "ended") then director:changeScene(e.target.scene) end end slide_sprt:insert( bck_sprt ) bck_sprt:addEventListener("touch",changeScene) return slide_sprt end init() |
Code Updated
Can you kindly provide either some plug and play code up upload a copy of your project somewhere? (Will make it easier to look over.)
Peach :)
it is the slider.lua, and the code posted above is the select_slider.lua, that include slider.lua

Try this (modified the only part that seems relevant to the issue) :

hmm not working, I'm also trying to.
i tried some differents forms, joint now in your answers, but the touch dont work, and if i use your code in last post the slide change position on the X coordinates.
