Problem getting real device bound

vitalitymobile · July 2015

Hi,
I used to get MINX, MAXX, MINY, MAXY by this code:

--static variable
local math_floor = math.floor;
local lw = application:getContentWidth()
local lh = application:getContentHeight()
_G.MINX = math_floor(-application:getLogicalTranslateX() / application:getLogicalScaleX())
_G.MINY = math_floor(-application:getLogicalTranslateY() / application:getLogicalScaleY())
_G.MAXX,_G.MAXY = lw - MINX,lh - MINY;
_G.W, _G.H = MAXX - MINX, MAXY - MINY;
_G.CX,_G.CY = MINX + W * 0.5, MINY + H * 0.5
 
print ( "MINX, MAXX, MINY, MAXY",MINX, MAXX, MINY, MAXY)

But in 2015.07.15 version, when i run gideros player on sony device ( 720 x 1280), it printout:

MINX, MAXX, MINY, MAXY	-112 	1312 	-0	800

It should be:

MINX, MAXX, MINY, MAXY	-58	1258	-0	800
(Tested in 2014.01)

(My project config as image attach)

Is this a bug or can you show the new codes to get real device bounds?

Thank!

Ah just found it!!! My sony device has soft button bar, so in 2014.01 version, it shows, but in 2015.07.15, it hides by default. That's why in my code, MINX changes between -58 and -112.

By the way, Here is simple code to draw two rects that fit the screen on all devices, and you can get MINX, MINY, MAXX, MAXY,Width, Height, CenterX, CenterY of screen. Maybe that help someone!

Yes, the code to hide the soft bar was added about then. If you slide in from that edge then it should appear.

Thank you @SinisterSoft

@vitalitymobile thank you for sharing, I was having the same issue and you saved me some work to point it out.

Just to add something I am not sure about: I read in various docs that lua handles multiplications faster than divisions, so you can change the /2 with *.5
I don't think that this would be a major improvement in performance, but maybe a bit here and another there would

Thanks @pie for a nice LUA tip! I've update the code and attach file. I also local math.floor as it is also another LUA tip
:P
