-= Double Post =-
ok i fixed it but, how do you TTF fonts and resize/color them then print with them?

look and psp-programming.com, the code part

the_undead - all ofthose questions can be answered by looking at the Lua Player Function Wiki. Try searching next timee ;)

you could link you know. its called helping. anyone can say search it takes a real helper to link ;)

Why? Its pretty easy to look for, If you cannot find it, Then your dumb.
http://wiki.ps2dev.org/psp:lua_player:functions
google "psp lua wiki"

Hooger - You dont learn anything having things hand fed to you... Alot of new developers need to learn they have a VAST amount of help/answers and information at their fingertips. Do they utilize this? More than not, N.O.

And honestly, after helping over 100 people or so, linking hte smae thing over and over is pointless and makes your realize 'this isnt getting through to these people, so why bother?'

haha, yea i know im lazy....lol next time ill look

Cuz this is a "HELP" thread :)
who knows, maybe he did search and found this thread as a result, but you have very good points there, you shouldn't really Give people EVERY code they ask for, linking to were they might find more help is a good way to help, but I see how that can get annoying and repetitive by doing it as many times as you do SG .

EDIT: ok, got a problem,
Im trying to make it so that if X is pressed, it changes the directory, and dofile's the "index.lua" in that directory... here is what i have so far...

Code:

---

        if pad:cross() and not oldpad:cross() and Select == 1 and bfold == false then
        System.currentDirectory("ms0:/PSP/GAME/BLK/GAMES/SpaceShark/")
        dofile("index.lua")
        end

---

when i do that, it sais it cannot find the directory or script file, and I double checked to make sure spelling was right, any ideas?

whats the problem with this: ?

Code:

---

image:drawLine(math.random(480), math.random(272), math.random(480), math.random(272), white)

---

your not defining the Range of math randoms you want, your just putting 272, or 480, try math.random(0,272) or math.random(0,480)

that way what ever you want will spawn between 0 and 272 OR 480 OR even both.

error: testovaci.lua:5: attempt to index global 'image' (a nil value)

strange o_O

Doesn't it have to be Image because lua is case sensitive?

Lol, thats it thx -_-

no probs. WIsh sg was online or yaustar right about now.

if you dont put the 0, LUA asumes a zero.

Someone called?

yes me sg gave me a snippet and im sure it would work but i'd like your explanation in the form of code. Because im very new to GU.

ARGH im gonna end up tearing my hair out. Now breathe. anybody else with knowledge of Gu care to help out as yaustar seems to have gone offline.

can you make a new folder on you ms with lua?.....this time i did search but i couldnt find anything.

Blame the fact I know nothing about the GU and the auto log out of QJ.

Code:

RED_COLOUR = Color.new( 255, 0, 0 );

SQUARE_POLYGON =
{
        { RED_COLOUR, -0.5,  0.5, -1.0 },
        { RED_COLOUR,  0.5,  0.5, -1.0 },

        { RED_COLOUR,  0.5, -0.5, -1.0 },
        { RED_COLOUR, -0.5, -0.5, -1.0 },
        { RED_COLOUR, -0.5,  0.5, -1.0 }
};

local gRotationAngle = 0;

while true do       
        Gu.start3d();
        Gu.clearDepth( 0 );
        Gu.clear( Gu.COLOR_BUFFER_BIT + Gu.DEPTH_BUFFER_BIT );
        Gum.matrixMode( Gu.PROJECTION );
        Gum.loadIdentity();
       
        Gum.perspective(75, 16/9, 0.5, 1000);

        Gum.matrixMode( Gu.VIEW );
        Gum.loadIdentity();

        Gum.matrixMode( Gu.MODEL );
        Gum.loadIdentity();

        Gu.disable( Gu.TEXTURE_2D );       
        Gum.translate(0, 0, -3.5);
        Gum.rotateXYZ( 0, 0, gRotationAngle * ( Gu.PI / 180.0 ) );       
        Gum.drawArray( Gu.TRIANGLES, Gu.COLOR_8888 + Gu.VERTEX_32BITF + Gu.TRANSFORM_3D, SQUARE_POLYGON );       
        Gu.end3d();

        screen.waitVblankStart();
        screen.flip();       
       
        gRotationAngle = gRotationAngle + 1;
       
        if Controls.read():start() then
                break;
        end
end

Out of this, what do you want explaining?

I wanted to ask if this would continuously rotate ? becuase that's what i want

Yea that will rotate because of this line:

Code:

---

Gum.rotateXYZ( 0, 0, gRotationAngle * ( Gu.PI / 180.0 ) );

---

And beacuse it is Pi, and Pi is infinite dived in half so it will continously rotate

Wrong, it constantly rotates because I increase the angle [gRotationAngle] every frame.

PI is also not infinity. It is 3.142 (and the rest of the PI precision).

HAHAHAHAHAHAHAHAHAHAHAHAH AHAHAHAHAHAHHAHAHAHAHA!! :ROFL: :ROFL: :ROFL: :ROFL: :ROFL: :ROFL: :ROFL:

sorry, that was funny as hell.

if the question asker didnt know, the ( Gu.PI / 180.0 ) is to convert from radians to degrees. (it could be vice versa, im laughing too hard to figure it out)

i figured out my problem

alas another day another problem. Yaustar that sorted it out perfectly thank you so much but it only looks good for when pad:left i want an opposite for if pad:right. PS : i tried gRotationAngle = gRotationAngle - 1 but it just goes backwards and this is not what i want.

Then what do you want?

Of course "gRotationAngle = gRotationAngle - 1" rotates backwards. What were you expecting it to do?

rotate other way ? what would this involve?

Code:

---

RED_COLOUR = Color.new( 255, 0, 0 );

SQUARE_POLYGON =
{
        { RED_COLOUR, -0.5,  0.5, -1.0 },
        { RED_COLOUR,  0.5,  0.5, -1.0 },
        { RED_COLOUR,  0.5, -0.5, -1.0 },
       
        { RED_COLOUR,  0.5, -0.5, -1.0 },
        { RED_COLOUR, -0.5, -0.5, -1.0 },
        { RED_COLOUR, -0.5,  0.5, -1.0 }
};

local gRotationAngle = 0;

while true do       
        Gu.start3d();
        Gu.clearDepth( 0 );
        Gu.clear( Gu.COLOR_BUFFER_BIT + Gu.DEPTH_BUFFER_BIT );
        Gum.matrixMode( Gu.PROJECTION );
        Gum.loadIdentity();
       
        Gum.perspective(75, 16/9, 0.5, 1000);

        Gum.matrixMode( Gu.VIEW );
        Gum.loadIdentity();

        Gum.matrixMode( Gu.MODEL );
        Gum.loadIdentity();

        Gu.disable( Gu.TEXTURE_2D );       
        Gum.translate(0, 0, -3.5);
        Gum.rotateXYZ( 0, 0, gRotationAngle * ( Gu.PI / 180.0 ) );       
        Gum.drawArray( Gu.TRIANGLES, Gu.COLOR_8888 + Gu.VERTEX_32BITF + Gu.TRANSFORM_3D, SQUARE_POLYGON );       
        Gu.end3d();

        screen.waitVblankStart();
        screen.flip();       
       
        if Controls.read():left() then
                gRotationAngle = gRotationAngle + 1;
        end
       
        if Controls.read():right() then
                gRotationAngle = gRotationAngle - 1;
        end
       
        if Controls.read():start() then
                break;
        end
end

Rotates left when you press left, rotates right when you press right.

Next time. Do. Not. Shout. At. Me. Ever.

I was not shouting just a typo. Internet went a bit haywire. Anyway but i want it to go --> that way instead of <-- that way

It does. You press left, it goes <-. You press right it goes ->

What do you want to be different?

Ever since I put the code to blit the weapons in it says.

Code:

---

error: index.lua:394: bad argument #2 to 'blit' (image expected, got nil)

---

Yet the image was loaded. And it worked before I put in the code to blit the weapons.

This is line 394.

Code:

---

screen:blit(redWall[3].x,redWall[3].y,redWall3)

Code:

screen:blit(blackWeapon[1].x,blackWeapon[1].y,blackGunr1)

blackGunr1 is a new variable. It doesn't exist/defined anywhere else in the code.

it doesnt go --> it just goes backwards

-> is backwards in terms of rotation. Be explicit in what you want it to do.

Wait ill try to tinker with it it might just look wierd because of the texture remaining the same

Thank you yaustar :D

New question: How can I remove from a table of strings any string that doesn't end in ".mp3"? And when that's done, will there be an element in my table that's nil, or do the other elements get shifted up?

New question: I have a bunch of strings stored in a table. How can I rearrange these strings randomly without any being repeated?

---

Randomly select two positions in the table
Swap the entries
Repeat

EDIT: Wow. Solving problems isn't as hard as it used to be... >_>

Yaustar now i know exactly what the problem is. The point of rotation of that cube is the top left vertice. i want the rotation point to be bang in the middle of the cube. Hope you can help.
