Mac OS Media

[MrPlow]

My compilation of the mac version of my app is not finding the media

Should I do a separate Media folder routine for Mac ?

I currently just see a FONT image instead of the main screen and graphics

Property a classic unix issue. Check your spelling on your filenames. Mac is case senative, unlike windows.

So pic.PNG is not the same as pic.png.

Ps. I'm did not spotted your name. You should been aware of this issue. Etc its could been in wrong png format (example using indexed mode), or id is the same.

Are you using virtual screens? It is not working on Mac and usually displays a bugged first loaded image, which could be the font file.
It happens with my game.

And dont forget to release all graphics before changing screen resolutions, otherwise they get corrupted.

Oh yes, is a issue with virtual screens on Mac, which is property that you see. Those screen dosent work on Mac.

This issue should been one of the most important to fix and then property the iOS 8 one.

Usescreen on mac fails totally? Does grabsprite work?

not sure what its fails, but no graphics is drawing correctly on virtual screen. Im thinks Erico Resolution test for Android is a great cadicate to test it on MacOS, because its did happens with that test as well:

im have not have problems in my games, but im also diddent uses virtual screens at all. But im cannot release it to appstore due vsync issue (but no worry, hurry at all).

[MrPlow]

It is as Erico said...
I get a font displayed instead of any graphics so it is the virtual screen issue...

I did solve it before for Viking Invaders using something else instead of stretchsprite etc...

I will look into that method...

im diddent uses virtual screens, due perforcement, which was about half too slow. So can you avoid it and uses a sort of PaintImage() function im uses, that could also approve speed very much.

Howover on Mac, its should not been that much penaty anyway, so its better to get that one fixed.

[MrPlow]

Hi SF,

I just checked your PaintImage() - nice!

But is it different to what I do already..?

I currently use createscreen, usescreen 0, draw everything then  clearscreen then usescreen -1 stretchsprite etc..?

How is it faster that what I do already...just trying to get my head around it...

Switching between virtual screens can use precious cpu time - it's OK on some machines, but hits others really hard.

[MrPlow]

Ah, I think I see what you're doing...

So instead of using the virtual screen you are drawing full on the fixed screen size then grabbing it and clearing the screen then drawing it scaled down or up to fit on the current screen res without using a screen switch (USESCREEN -1)?

[spacefractal]

My game newer user scaled screens, but using ZOOMSPRITES/POLYVECTOR as well DRAWANIM (depend on image) directly to the backbuffer to avoid the virtual screen. The Assest files also often uses 2 size of the image, so im can choice the bigger or the smaller one to avoid using too much memory or scaling. But that can been a quite compliced sometimes.

You could eventuelly play and change the function to support DRAWANIM and/or POLYVECTOR, but that is not my job. PaintImage() showed in the codesnippet was a possible how scaling can been performed, but its can been used on other purphose as well.

But in the end im do not uses CREATESCREEN at all, due speed penaty. Im saw Genius Greedy Mouse performed in a half speed on a Android device with virtual screen, so im dropped that idea.
