let me know if I put too much, maybe you want 1 question at a time
I’m trying to make the sprite work on my storyboard. The sprite is the one on Corona sample, the one with the cat and the green dude.
The problem it’s that the code works in one view, main.lua, but I’m trying to find the logic to make it work on storyboard, and I’m going crazy, please I need some help.
************************************* ONE************************************
it has a table
-- a bunch of foliage local tree = {} tree[1] = display.newImage( "a2.png" ) tree[1].xScale = 0.8; tree[1].yScale = 0.8 tree[1]:setReferencePoint( display.BottomCenterReferencePoint ) tree[1].x = 20; tree[1].y = baseline tree[1].dx = 0.1 tree[2] = display.newImage( "a3.png" ) tree[2].xScale = 0.6; tree[2].yScale = 0.6 tree[2]:setReferencePoint( display.BottomCenterReferencePoint ) tree[2].x = 120; tree[2].y = baseline tree[2].dx = 0.2
with many trees, where do I create the table,
in the createScene, or the enterScene? and how do I remove the table when I leave the scene?
in the exitScene, or the destroyScene?
Does it need a special code to remove the table, like the remove on exitScene
display.remove(spider1)
or the button one in destroyScene
if buttonBack then buttonBack:removeSelf() buttonBack = nil end

The background I think I know how to do that.
Then is the actual sprite sheet
-- an image sheet with a cat local sheet1 = graphics.newImageSheet( "a10.png", { width=512, height=256, numFrames=8 } ) -- play 8 frames every 1000 ms local instance1 = display.newSprite( sheet1, { name="cat", start=1, count=8, time=1000 } ) instance1.x = display.contentWidth / 4 + 40 instance1.y = baseline - 75 instance1.xScale = .5 instance1.yScale = .5 instance1:play()
I guess the image sheet I have to insert that in to the group of the scene. is that correct?
local sheet1 = graphics.newImageSheet( "a10.png", { width=512, height=256, numFrames=8 } ) group:insert ( sheet1 )
and the actual sprite sheet, do I treat like a .png file
local instance1 = display.newSprite( sheet1, { name="cat", start=1, count=8, time=1000 } ) group:insert ( instance1 )
Is it like that or is there another way?, to create it and to remove it.
*********************************3***************
Then we have the grass movement, do I do that in what scene, and how do I
remove it later
-- Grass -- This is doubled so we can slide it -- When one of the grass images slides offscreen, we move it all the way to the right of the next one. local grass = display.newImage( "a13.png" ) grass:setReferencePoint( display.CenterLeftReferencePoint ) grass.x = 0 grass.y = baseline - 20 local grass2 = display.newImage( "a13.png" ) grass2:setReferencePoint( display.CenterLeftReferencePoint ) grass2.x = 480 grass2.y = baseline - 20
same with the rec for the baseline
-- solid ground, doesn't need to move local ground = display.newRect( 0, baseline, 480, 90 ) ground:setFillColor( 0x31, 0x5a, 0x18 )
*************************4***************************
The we have the actual function that makes everything works
-- A per-frame event to move the elements local tPrevious = system.getTimer() local function move(event) local tDelta = event.time - tPrevious tPrevious = event.time local xOffset = ( 0.2 \* tDelta ) grass.x = grass.x - xOffset grass2.x = grass2.x - xOffset if (grass.x + grass.contentWidth) \< 0 then grass:translate( 480 \* 2, 0) end if (grass2.x + grass2.contentWidth) \< 0 then grass2:translate( 480 \* 2, 0) end local i for i = 1, #tree, 1 do tree[i].x = tree[i].x - tree[i].dx \* tDelta \* 0.2 if (tree[i].x + tree[i].contentWidth) \< 0 then tree[i]:translate( 480 + tree[i].contentWidth \* 2, 0 ) end end end -- Start everything moving Runtime:addEventListener( "enterFrame", move );
I guess I have to put that function first on top of the file, before all the create scenes functions?
but where do I put the
-- Start everything moving Runtime:addEventListener( "enterFrame", move );
at the end, - after or before the
scene:addEventListener( "createScene", scene ) scene:addEventListener( "destroyScene", scene ) return scene
*********************5**********************
I want to have a button that makes the sprite move
I guess I create a button normally, and use – onRelease
to call the function – move(event)
to actually start the animation.
In the sample as soon as you load the app, the cat is running
I want the cat to run when people push the button.
And how do you stop the animation, or the sprite
in the sample, is running forever, never stops.
**********************6**********************
Sorry for so many questions, but I guess I want to make this work
and I have no clue, where to find all these answers, instead of asking
one at a time and back an forth, I hope I can get all the answers to’
actually make a sprite work in storyboard.
Thanks for your help.
PS. - This is for my second app, the first one is already on the app store
thanks to all of you, thank you a lot.
