Screen Limits

david_miguel95 · May 3, 2016, 8:08am

I have this code to the walls , or the full screenshot limits for my application but does not work , someone can help me figure out the error ??

-- Limites do ecrã local borderTop = display.newRect( 0, 0, 707, 1 ) borderTop:setFillColor( 0, 0, 0, 0) -- Invisivel physics.addBody( borderTop, "static", borderBodyElement ) sceneGroup:insert(borderTop) local borderBottom = display.newRect( 0, 1000, 707, 1 ) borderBottom:setFillColor( 0, 0, 0, 0) -- Invisivel physics.addBody( borderBottom, "static", borderBodyElement ) sceneGroup:insert(borderBottom) local borderLeft = display.newRect( 0, 1, 1, 1000 ) borderLeft:setFillColor( 0, 0, 0, 0) -- Invisivel physics.addBody( borderLeft, "static", borderBodyElement ) sceneGroup:insert(borderLeft) local borderRight = display.newRect( 707, 1, 1, 1000 ) borderRight:setFillColor( 0, 0, 0, 0) -- Invisivel physics.addBody( borderRight, "static", borderBodyElement ) sceneGroup:insert(borderRight)

Since your rectangles are only 1 pixel wide (or high), there is no interior area to fill – have you tried rect:setStrokeColor(…) and rect.strokeWidth=… ??

Continuo sem conseguir com que o meu código funcione

I’m not sure what you are trying to achieve or what exactly isn’t working.

Can you clarify your question?

david_miguel95 · May 9, 2016, 2:05pm

I want my screen has limits, that is , I have an image of a field as background and the rest could not leave the background , could not leave the mobile phone screen

torbenratzlaff · May 10, 2016, 9:05pm

Hey, I’m just guessing here, as your english is quite horrible. (due to your translation software I suppose)

The way you created the borders is correct, but you have to keep two things in mind.

The things you want to keep inside the screen boundaries needs to have a body as well. (a dynamic one) https://docs.coronalabs.com/api/library/physics/addBody.html
You should adjust the borders to the actual screen size (not a fixed value like 770).

https://docs.coronalabs.com/api/library/display/viewableContentWidth.html

https://docs.coronalabs.com/api/library/display/viewableContentHeight.html

Hope that helps.

If not, please clarify your question.

Irony at it’s finest

torbenratzlaff · May 11, 2016, 3:15pm

I wish I could say, that it was intended

david_miguel95 · May 12, 2016, 8:45am

Still does not work …
I know that English is terrible , but Google Tradudor not help much xD

This is the application code if I could help find out where the error , thanked :wub:

torbenratzlaff · May 12, 2016, 6:13pm

So, this is the code you use. But what is the problem with it?
Which object should stay inside the borders and when does it fails to do so?

Actually you are using only static bodys, so there is nothing that could collide (only “dynamic” bodys collide with others).

david_miguel95 · May 12, 2016, 8:09pm

The " Camisola " were to stay in the background …
I changed it to " Dynamic " but now the bodies disappear from the screen

torbenratzlaff · May 12, 2016, 8:15pm

Only set the Camisolas body to dynamic, leave the others static.

david_miguel95 · May 12, 2016, 10:05pm

But what is " dynamic" falls of the screen , there is no way to stop ?

torbenratzlaff · May 13, 2016, 8:41am

The static borders should preent the dynamic Camisolas from falling out of the screen.

I thought that was your intend in the first place?

david_miguel95 · May 13, 2016, 10:23am

Maybe that is easier to understand, the t - shirts can not leave the field , which is the background , they start with a preset position and then the user changes to where you want …

torbenratzlaff · May 13, 2016, 10:51am

Ah, I think I understand now.

The user should not be able to place the T-Shrits outside of the field?

If that’s what you want to achieve, physics are not the right way to do it.

Inside your touch function you have to check if the current position is insie the field. If yes, aplly it to the shirt, if not, it should stay where it is.

david_miguel95 · May 13, 2016, 11:02am

Yes!!! It is !!!
But how do I do it is that I can not even, I tried a thousand ways and does not give

local function camisolaTouch(event) local touchedObject = event.target if event.phase == "began" then touchedObject.previousX = touchedObject.x touchedObject.previousY = touchedObject.y -- Marca o objeto como alvo local parent = touchedObject.parent parent:insert( touchedObject ) display.getCurrentStage():setFocus( touchedObject ) -- Localiza e seleciona o alvo, assim o utilizador pode mudar de objeto touchedObject.isFocus = true elseif event.phase == "moved" or "cancelled" == event.phase then display.getCurrentStage():setFocus( nil ) touchedObject.isFocus = false touchedObject.x = (event.x - event.xStart) + touchedObject.previousX touchedObject.y = (event.y - event.yStart) + touchedObject.previousY end return true end

In that part of the function I have to get the If’s?

torbenratzlaff · May 13, 2016, 11:19am

Try something like this:

local fieldWidth = 1000 local fieldHeight = 600 local fieldCenterX = 1200 local fieldCenterY = 700 local fieldBoundLeft = fieldCenterX - fieldWidth\*0.5 local fieldBoundRight = fieldCenterX + fieldWidth\*0.5 local fieldBoundTop = fieldCenterY - fieldHeight\*0.5 local fieldBoundBottom = fieldCenterY + fieldHeight\*0.5 local function camisolaTouch(event) local touchedObject = event.target local eventPhase = event.phase if eventPhase == "began" then touchedObject.startX = touchedObject.x touchedObject.startY = touchedObject.y local parent = touchedObject.parent parent:insert( touchedObject ) display.getCurrentStage():setFocus( touchedObject ) touchedObject.isFocus = true elseif touchedObject.isFocus then if eventPhase == "moved" then touchedObject.x = (event.x - event.xStart) + touchedObject.startX touchedObject.y = (event.y - event.yStart) + touchedObject.startY else display.getCurrentStage():setFocus( nil ) touchedObject.isFocus = nil local newX = (event.x - event.xStart) + touchedObject.startX local newY = (event.y - event.yStart) + touchedObject.startY if newX \>= fieldBoundLeft and newX \<= fieldBoundRight and newY \>= fieldBoundTop and newY \<= fieldBoundBottom then touchedObject.x = newX touchedObject.y = newY else touchedObject.x = touchedObject.startX touchedObject.y = touchedObject.startY end touchedObject.startX = nil touchedObject.startY = nil end end return true end

First I estimented the field bounds from it’s width, height and center position.

Inside the ended event of the touch listener I test if the current position of the object is inside those bounds. If yes, it’s placed there, if not it returns to it’s starting position.

david_miguel95 · May 13, 2016, 2:35pm

But if I use these variables Field the background will no longer be responsive

torbenratzlaff · May 13, 2016, 3:06pm

Well, than change the values to be responsive

That are just dummy values I chose, can be any values you want.
