Arcade InterfaceTexturedRect

LegoGirl · Post by **LegoGirl** » Tue Feb 03, 2004 3:44 pm

I'm having a little trouble with "InterfaceTexturedRect". My texture is 512x512 with 16x16pixel images on it (giving 32x32 images).

Drawing image 0 is fine so it looks like the height and width are correct. But other images (when fU and fV are not zero) don't appear correctly.

Any ideas?

Code: Select all

int nX = nImage % 32;
int nY = nImage / 32;
float fU = (1.0f/32.0f) * (float)nX;
float fV = (1.0f/32.0f) * (float)nY;
float fUWidth = 1.0f/32.0f;
float fUHeight = 1.0f/32.0f;

InterfaceTexturedRect(
    0, gnSpritesOverlay,
    nScreenX, nScreenY,
    16, 16,
    0xFFFFFFFF,
    fU, fV,
    fUWidth, fUHeight );

And I should probably add that the following does work....I just don't want square textures

Code: Select all

InterfaceSprite(
    0, gnSpritesOverlay,
    nScreenX, nScreenY,
    1.0f/32.0f,
    nImage,
    0xFFFFFFFF,
    0.0f, 0.0f );

oooh lego playing with the arcade? wooohooo!!! :]

ah ok.. um.. thats either a docs issue or a code bug depending on which bit seems wrong

The final two parameters should actually be U2 and V2.. i.e. they're not width and height, they're the absolute positions of the bottom right hand texture coord.
soo...

float fUWidth = fU + 1.0f/32.0f;
float fUHeight = fV + 1.0f/32.0f;

..should fix it.

Any preference for whether i change the code or docs to fix that properly?

Excellent. That sorted it out.
I'd just fix the doc and header file, saves breaking the thousands of games already written

when you next in town for a beer?

Whenever the next "event" takes place. Just give us a shout.

LegoGirl · Post by **LegoGirl** » Tue Feb 03, 2004 5:34 pm

Just got a...

Code: Select all

**** Error Message ****
Too many rectanges added to a textured overlay

...so what's the limit then?

Post by **Mit** » Tue Feb 03, 2004 6:05 pm

apparently its 64.
which is a bit crap really

is 512 enough? This patch ups the limit, as well as fixing up the other texturerect stuff in the header...

Lemme know if you think you'll want more than that - is no problem increasing the limit some more if needs be.

and right.. i better get arrangin some sort of 'event' soon then. Isnt early march the anniversary of LMA becoming Number 1! ?

(I have no idea, of course, but any excuse for a pansy will do..)

Thanks for upping it, Mit, was gonna ask that at some point myself..

Do I hear something about a pansy-up? any chance a coupla 'youths' like Me and Tom can gatecrash?

is 512 enough?

That's just fine...for now

Thanks.

That's just fine...for now

And now it isn't...tish..

I'll just keep hitting "Ignore" for now. Could it be game selectable or will that break a whole lotta stuff?

ooh, so what u doin thats using more than 512 sprites? :] is it pretty?

No problem to change it.
Previously it was a fixed size buffer for each layer (maximum 16 layers with 512 in each), so ive change it to a nice lil pool shared between the layers instead.
The current default is 1024 shapes max, but ya can change that at runtime using

InterfaceSetGlobalParam( INTF_TEXTURERECT_LIMIT, <Value> );

with <Value> obviously defining the maximum number of shapes ya can have on screen at once. Theres a overhead of about 48 bytes per shape so you should be safe using even pretty silly values in there. :]
Theres still the limit of 16 different layers to use - thats on a define so i can up it easily if needs be, but would be a bit trickier to make that dynamic... assuming thats not a problem yet anyway..

Heres a new zip of the arcade stuff with that and the line fix in it..

(p.s. course.. i aint actually properly tested any of it ;] )

Um. There might be a bug in there. After playing for a little while the arcade machine screen is going blank..tho once I had a line still visible but all of the sprites and rects had gone. It seems to be getting into an infinite loop somewhere in interface.

Post by **Mit** » Thu Feb 05, 2004 5:47 pm

prolly should have properly tested it then

had a quick look for anythin obvious and tidied up so bits.. see if
http://i-lands.net/intpatch2feb04.zip

..works any better? It seems to cope with the invaders game ok but then thats not exactly pushin it. If it still dont work ill set up a more thorough test later this evenin

LegoGirl · Post by **LegoGirl** » Thu Feb 05, 2004 7:33 pm

Ah..yes that's fixed it...ta
Does the "layer" parameter really work? I can't seem to move things forward.

Post by **Mit** » Thu Feb 05, 2004 11:21 pm

phew

um, not really

.. works for fonts on 0,1 or 2, and untextured rectangles on 0 or 1, but i only jus added it for the draw methods in general and havent done the implentation yet. Anythin ya need doin sooner rather than lata?

LegoGirl · Post by **LegoGirl** » Fri Feb 06, 2004 10:59 am

Ah, that explains stuff. I'll just pretend they work for now. Right now I'm only using TexturedRects so when you get a sec that's the one to do (for me anyway

). 3 layers should make it look ok.

k, will do. Im away at the weekend so it'll probably be monday before i can get that to ya.

While you're looking at it could you check to see if you're doing something "special" when nX and nY are both -1.

Code: Select all

InterfaceTexturedRect(
    0, gnCharSetOverlay,
    -1, -1, // <-- This right 'ere
    8, 8,
    0xFFFFFFFF,
    fU1, fV1, fU2, fV2 );

Post by **Mit** » Mon Feb 09, 2004 4:33 pm

Yeh, -1, -1 is used to denote an image that should be centered on the screen. Did i not mention that in the docs? ;]

Can be changed if its a problem? .. (tho anything less than 0 really isnt a valid param for the coordinate).
