Yes but it does only with max2D commands (drawrect, drawcircle, plot etc...), with images (without filtering) it works perfectly.

The above example is using images.  Here is the same thing but with an image containing 4 lines.

The problem is the way SetVirtualResolution renders fractional pixels.  for example, here is a line scaled twice the size
{X}{X}|{X}{X}
{X}{X}|{X}{X}
-------------
{ }{ }|{ }{ }
{ }{ }|{ }{ }
Each bracket represents one actual pixel, while a 2x2 group represents one virtual pixel.  Now if I were to draw the line at y of  0.5 instead of 0.0, then either the line will be drawn at the next full pixel or stay where it is depending on how the values get rounded.
{ }{ }|{ }{ }
{ }{ }|{ }{ }
-------------
{X}{X}|{X}{X}
{X}{X}|{X}{X}
But when you use virtual resolution, it will render on the "Half pixel" or a full normal pixel like so
{ }{ }|{ }{ }
{X}{X}|{X}{X}
-------------
{X}{X}|{X}{X}
{ }{ }|{ }{ }
Which kills the 320x200 look.  At least, that is the way it behaves in Max2D, might be different with other engines.

I found the exact same issue with rotations on images using the render resolution instead of the virtual resolution. So was happy when I did make it work properly.

I'll probably use AGK on this project, care to elaborate Qube?  I'm working on graphics before code.

In AGK to make sure rotations don't use the render resolution and break the 320x200 look or be blurry when scaled up ( rough code outline ) :


SetDisplayAspect( 320 / 200 )
SetVirtualResolution ( 320, 200 )
SetDefaultMinFilter( 0 )
SetDefaultMagFilter( 0 )

gameImage = CreateRenderImage ( 320, 200, 0, 0 )
gameSprite = CreateSprite( gameImage )

Do
SetRenderToImage( gameImage, 0 )
ClearScreen()

// do all you fancy drawing stuff here

SetRenderToScreen()
DrawSprite( gameSprite )

Swap()
Loop


Oh, ok - thanks.

Perhaps I need something different as I intend to scale up my game screen 320 X 200 (plus border) 4 times to fit a 1920 X 1080 screen.  So just load and scale all my graphics I guess (without filtering).

The above code is for scaling for any resolution. You can set your window size to 1920x1080 and the exact same code applies.

Ah, the devil is in the detail.  Good stuff, thanks.

Oh yes you're right, I don't know why I didn't noticed it with images and thought it was ok...

You can still use this eventually :
SuperStrict
SeedRnd MilliSecs()

SetGraphicsDriver GLMax2DDriver()

Graphics 1280,720,0,60
SetClsColor 100,100,100

Local widthScale:Int = Floor(GraphicsWidth()/320.0)
Local heightScale:Int = Floor(GraphicsHeight()/200.0)
Local gfxScale:Int = Min(widthScale,heightScale)

Local bufferImage:TImage = CreateImage(320,200,1,DYNAMICIMAGE)
Local bufferX:Int = (GraphicsWidth()-320*gfxScale)/2
Local bufferY:Int = (GraphicsHeight()-200*gfxScale)/2

Local rotation:Float

While Not KeyHit(KEY_ESCAPE) And Not AppTerminate()

Cls

' ////////// YOUR GAME HERE
SetScale 1,1
rotation = rotation + 1
SetRotation rotation
DrawRect 160,100,50,50


' ////////// GRAB THE BUFFER IMAGE FROM 0,0 TO 320,200
GrabImage bufferImage,0,0
Cls
SetColor 0,0,0
SetRotation 0
DrawRect 0,0,GraphicsWidth(),GraphicsHeight()
SetScale gfxScale,gfxScale
SetColor 255,255,255
DrawImage bufferImage,bufferX,bufferY

Flip

Wend

End

It will grab an image from 0,0 to 320,200 and scale it automatically to the best size.

Currently have a freaky fun time creating synth music - Never done synth music with modern day tools but woot woot it's great fun. No doubt you lot will think my creations are just nuts and sound like a jingly old mess but at least I'm giving it a go... Gotta push yourself.

I think after this I'll treat myself to a tip top synth VST as I'm just having too much fun not to invest... But for now, the free synth VST's are really really good.

Are you using re-noise?

Yup. Been using Renoise for years. It's the best tracker I've come across and I was soooo glad to find it after all those years in Amiga land using NoiseTracker / ProTracker / OctaMED. An amazing plus point is it has VST support \o/ - Long live Renoise!!!

The free VST synth by Daichi "Synth1" is really quite amazing. Sounds great. Tons of presets available on the 'net, too

Have that one downloaded and will have a play, thanks.

Cool, will have a listen later when I get home

Here's mine so far (attached)

Working on tilemap collisions regarding slopes... Its been donkeys since I wrote a platformer with slopes (Well, donkeys since I've wrote anything really, lol), I forgot about the usual pitfalls, but, it came back in the end!

With this, I can check the tile the character is on, and work out the angle of the slope to make the character 90' from the slope if needed, a bit like Sonic, I wont need it for this, but, its future proofing it if I ever decide to do something "proper"!

Yes, the resolution isnt set yet, but, I can tweak it by changing a few constants, and it should be tickety boo.

Right, so, with that, I can happily move on to cobbling a game out of it!

Very nice.  So it looks like we're all doing platform games?  Me included.

The thing is... I'm pleased its retro, because I dont have to really rely on graphics, as that's my usual downfall... Like, I can do them, but, it's a chore and I get bored, very very quickl !

And I havent got a consistent style either... I'll work on something for ages, plonk it in the game, and it just looks wrong, so I'll scrap it, restart... Nah... Takes me forever to get stuff right!

So for me, this competition has been inviting for me, because I've suffered coders block for ages, and I'm talking ages mind, and it's always the graphical part that puts me off... When I did iOS games, they were small, graphics didnt need as much work, I got by and finished them. Scaling up from that, well, I'd rather be hanging off the arse end of a hand grinder grinding piss ridden concrete... With no face mask!

Right, X-Factor styleee sad tiny violin playing "I'm on a journey" craic out of the way, time to start crunching the res down and getting some proper shite retro graphics in there! hehehe
