2D draw methods/ Java -> C++

Nine_Masquerade_ · Post by **Nine_Masquerade_** » Mon Jul 20, 2009 10:11 am

Hi, i am completely new to C++ coming entirely from a Java background and was wondering which C++/PSP lib functions would do the following:

-Created a buffered image with set width and height.

-Draw an image to an x and y coordinate on that buffered image.

-Blit the buffered image to the PSP screen.

So far i have come this far with my code using the files from this page (files are found in the second paragraph):

http://www.psp-programming.com/tutorial ... on04-2.htm

Code: Select all

#include <pspdisplay.h>
#include <pspctrl.h>
#include <pspkernel.h>
#include <pspdebug.h>
#include <pspgu.h>
#include <png.h>
#include <stdio.h>
#include "graphics.h"

PSP_MODULE_INFO&#40;"Image Display Program", 0, 1, 1&#41;;

#define printf pspDebugScreenPrintf

/* Exit callback */
int exit_callback&#40;int arg1, int arg2, void *common&#41; &#123;
          sceKernelExitGame&#40;&#41;;
          return 0;
&#125;

/* Callback thread */
int CallbackThread&#40;SceSize args, void *argp&#41; &#123;
          int cbid;

          cbid = sceKernelCreateCallback&#40;"Exit Callback", exit_callback, NULL&#41;;
          sceKernelRegisterExitCallback&#40;cbid&#41;;

          sceKernelSleepThreadCB&#40;&#41;;

          return 0;
&#125;

/* Sets up the callback thread and returns its thread id */
int SetupCallbacks&#40;void&#41; &#123;
          int thid = 0;

          thid = sceKernelCreateThread&#40;"update_thread", CallbackThread, 0x11, 0xFA0, 0, 0&#41;;
          if&#40;thid >= 0&#41; &#123;
                    sceKernelStartThread&#40;thid, 0, 0&#41;;
          &#125;

          return thid;
&#125;

int main&#40;&#41; &#123;
	char buffer&#91;200&#93;;
	Image* ourImage;
	pspDebugScreenInit&#40;&#41;;
	SetupCallbacks&#40;&#41;;
	initGraphics&#40;&#41;;
	sprintf&#40;buffer, "cylus.png"&#41;;
	ourImage = loadImage&#40;buffer&#41;;
	int x = 240;
	int y = 136;
	sceDisplayWaitVblankStart&#40;&#41;;
	SceCtrlData pad;
	while&#40;1&#41;
	&#123;
		sceCtrlReadBufferPositive&#40;&pad, 1&#41;;
		if&#40;pad.Buttons & PSP_CTRL_LEFT&#41;
			x--;
		if&#40;pad.Buttons & PSP_CTRL_RIGHT&#41;
				x++;
		if&#40;pad.Buttons & PSP_CTRL_UP&#41;
				y--;
		if&#40;pad.Buttons & PSP_CTRL_DOWN&#41;
				y++;
		if&#40;pad.Buttons & PSP_CTRL_TRIANGLE&#41;
				break;
		blitAlphaImageToScreen&#40;0 ,0 ,16 , 20, ourImage, x, y&#41;;
		flipScreen&#40;&#41;;
	&#125;
	sceKernelSleepThread&#40;&#41;;
	return 0;
&#125;

The problem is, the sprite draws to the screen and successfully moves, but the screen does not refresh to being blank before the next coordinate is drawn. Redrawing to a buffered image 480x272 and then blitting that to the screen would avoid this and is the method i usually use in my Java programs.

Any help is greatly appreciated!

You have to clear the draw buffer.
use
clearScreen(0);
before drawing

>Redrawing to a buffered image 480x272 and then blitting that to the screen would avoid this and is the method i usually use in my Java programs.

That would be to avoid flickering and the pspgu uses double buffering, you'd still have to clear the screen.

Thanks! It works perfectly.

A couple other questions:

-How do you define a custom color (through RBG values) and then set the background as that color?

-is it possible to have a constructor take main as a parameter so that i can do main.blitImageToScreen(blah, blah, blah); as the draw method within a object?

-Also i have both .c files and .cpp files in my project folder. can C and C++ files be used together??

>How do you define a custom color (through RBG values) and then set the background as that color?

open up graphics.c and go to the clearScreen and add
sceGuClearColor(color);
before
sceGuClear(GU_COLOR_BUFFER_BIT|GU_DEPTH_BUFFER_BIT);

then
when calling clearScreen, pass the colour you want to use as the background colour.
use GU_RGBA(r,g,b,a) to make your colour from red,green, blue ,and alpha values.
if you get an undefined reference to GU_RGBA add
#include <pspgu.h> to you code.

>Also i have both .c files and .cpp files in my project folder. can C and C++ files be used together??

Sure

>is it possible to have a constructor take main as a parameter so that i can do main.blitImageToScreen(blah, blah, blah); as the draw method within a object?

what?

Nine_Masquerade_ · Post by **Nine_Masquerade_** » Tue Jul 21, 2009 7:39 am

Thanks for your very prompt and comprehensible tips psPea; it works great!

What I meant by this:

>is it possible to have a constructor take main as a parameter so that i can do main.blitImageToScreen(blah, blah, blah); as the draw method within a object?

Is this:

Suppose I had a class called "You". In the java version of my game, the constructor takes in an "Applet".

Code: Select all

public You&#40;Applet myApplet&#41;
	&#123;
	code
	&#125;

So in the Applet itself, when you declare the You object, you see:

Code: Select all

y = new You&#40;this&#41;;

In the java version "You" gets the character/blood images through myApplet like so:

Code: Select all

		for&#40;int i = 0; i < 8; i++&#41;
		&#123;
		img = myApplet.getImage&#40;myApplet.getCodeBase&#40;&#41;, "blood"+i+".png"&#41;;
		blood.add&#40;img&#41;;
		&#125;

The Applet that is being passed into "You" in the java version is basically main.c for the C/C++ version (both contain the main method for the program).

So my question is (in regards to the C/C++ version)... can i pass main.c into "You"'s constructor as a parameter like so:

Code: Select all

You&#58;&#58;You&#40;main m&#41;
&#123;
code
&#125;

so as to then call

Code: Select all

sprintf&#40;buffer, "cylus.png"&#41;;
	ourImage = loadImage&#40;buffer&#41;;

and

Code: Select all

blitAlphaImageToScreen&#40;0 ,0 ,16 , 20, ourImage, x, y&#41;;

so that "You" can instantiate and govern its own .pngs and have its own "draw" method yet do it by using main.c?

Basically what I am asking is can main.c be passed as a parameter and then used in methods inside of other objects?

No. You need to go review your C++ a bit. Remember that C++ is the same on the PSP as on any other platform. If you can/can't do it on a PC, you can/can't do it on the PSP.

psPea · Post by **psPea** » Tue Jul 21, 2009 8:30 am

I've never used applets in Java so I have no clue what you're talking about.

>So my question is (in regards to the C/C++ version)... can i pass main.c into "You"'s constructor as a parameter like so:

I'm not sure what you mean, but I'm certain the answer is no.

If you want "You" to instantiate and govern its own .pngs and have its own "draw" method, then do it, you don't need main.

Code: Select all

class You&#123;
.
.
.
public&#58;
         You&#40;&#41;&#123;
          for&#40;int i = 0; i < 8; i++&#41; &#123; 
            char file&#91;100&#93;;     
            sprintf&#40;file, "blood%d.png", i&#41;;                
            Image img = loadImage&#40;file&#41;; 
            blood.insert&#40;img&#41;; 
          &#125;
         &#125;
         draw&#40;int srcx ,int srcy ,int width, int height, Image *ourImage, int x, int y&#41;&#123;
            blitAlphaImageToScreen&#40;srcx ,srcy ,width, height, ourImage, x, y&#41;;
         &#125;
.
.
.
&#125;;

lol i agree J.F.. I do need to review my C++ a bit. Ive realized what i was trying to do didnt make too much sense, so what im trying now is this (just an example from within "You.h"):

Code: Select all

		for&#40; int i = 0; i < 6; i++ &#41;
		&#123;
			sprintf&#40;buffer, "cylus"+i+".png"&#41;;
			img = loadImage&#40;buffer&#41;;
			playerPics&#91;i&#93; = im;
		&#125;

Im currently still making changes, but ill let you know if what im trying works. And I apologize if it is at times annoying that i am not too adept with C++. Ive found that the fastest way to learn and retain a language is through trial and error and i appreciate all of the help ive been given more than you guys can imagine :)

Nine_Masquerade_ · Post by **Nine_Masquerade_** » Tue Jul 21, 2009 8:37 am

I was just gonna try that psPea.
Working on it now...

Nine_Masquerade_ · Post by **Nine_Masquerade_** » Tue Jul 21, 2009 10:44 am

Almost done.
Quick question though.

Can i make ArrayLists in C++ like i can in Java?

Im almost positive i cant, but its strange because dont have any syntax errors for lines like this:

Code: Select all

	ArrayList<Image> flamethrower = new ArrayList<Image>&#40;&#41;;

yet for some reason when i try making an ArrayList of ArrayLists like this:

Code: Select all

ArrayList<ArrayList<Image>> weapon = new ArrayList<ArrayList<Image>>&#40;&#41;;

i get a syntax error.
Please let me know if im wrong about ArrayLists in C++ and if im not, it would help a bunch if you know why im getting this error.

psPea · Post by **psPea** » Tue Jul 21, 2009 11:14 am

put a space between the two >
change >>
to > >

also I didn't know there was ArrayList in C++

Nine_Masquerade_ · Post by **Nine_Masquerade_** » Tue Jul 21, 2009 11:20 am

lol thats why i changed my post to "im almost positive i cant".
The error went away when i did what you said, but i did a little test, where i misspell "ArrayList", save, and no errors show up...

Im not sure why its not detecting a syntax error when i misspell ArrayList.

Ill see what happens when i finish transcoding it to C++ and try and compile.

Fingers are crossed.

Nine_Masquerade_ · Post by **Nine_Masquerade_** » Tue Jul 21, 2009 11:37 am

Hmm found something worth looking at.
I ran my java source through a java -> C++ translator and it changed the ArrayLists like this:

Code: Select all

ArrayList<Image> flamethrower = new ArrayList<Image>&#40;&#41;;

is now

Code: Select all

std&#58;&#58;vector<Image*> flamethrower = std&#58;&#58;vector<Image*>&#40;&#41;;

I am not too sure what this means. Could someone enlighten me?

psPea · Post by **psPea** » Tue Jul 21, 2009 11:53 am

http://www.cplusplus.com/reference/stl/vector/
and
http://www.cplusplus.com/reference/

one thing to note in Java object variables store reference to objects, in C++ that's not the case, notice how they changed Image to Image*.
If you add an object to any of those containers they add a copy of it and not the object itself, so making the vector type a pointer to the object may be more desireable.

Nine_Masquerade_ · Post by **Nine_Masquerade_** » Tue Jul 21, 2009 12:16 pm

Thank you. This helps tremendously.

I am using eclipse Galileo and i know for a fact there are many syntax errors that are not being shown. Having realized this, this process may take a couple more days :( but im up to the task. Is there something I can change in my eclipse preferences so these errors will show?

Also, in java as you probably know there is a built in Rectangle object, which i use extensively for collision tests in my code. Do you know if C++ has a Rectangle object that contains functions which tell if something is inside the Rectangle, on its border, etc.?

why not try running the rectangle class through the converter?

All i found for the java Rectangle class source was this:

http://kickjava.com/src/java/awt/Rectangle.java.htm

I also found this

http://www.gtkmm.org/docs/gtkmm-2.4/doc ... angle.html

Which i think might prove to be more practical. But since im developing under MinPSPw, im not sure how to install these packages. Any ideas?

Nine_Masquerade_ · Post by **Nine_Masquerade_** » Wed Jul 22, 2009 11:43 am

Im just going to make my own rectangle class using this algorithm:

In the case of axis-aligned ones, there are at most four checks you need to perform:
1. Check if box A is completely to the left of box B (a.left <= b.right). If so, then quit the process: they don't intersect.
2. Otherwise, check if it's completely to the right (a.right >= b.left). If so, quit the process.
3. If not, check if it's completely above box B (a.bottom >= b.top). If so, quit.
4. If not, check if it's completely beneath box B (a.top <= b.bottom). If so, quit.
If not, then the boxes intersect.

Thanks for your continued help psPea.

I renamed main.c to main.cpp and added -lstdc++ to LIBS.

Now i get this error:

I'm now reading your code and I see that Rectangle.h isn't included in main

also I believe graphics.h isn't wrapped in an extern "C"
so
change
#include "graphics.h"
to
extern "C"
{
#include "graphics.h"
}

Yes that did solve that error, but now sadly i am getting more...

I am extremely grateful for any help people can offer.

I'm thinking your header files aren't found
are they in the same folder as you.h
if so change
#include <header.h>
to
#include "header.h"

Thanks! Yea, the header files are all in the same directory. That helped me narrow down the error log to this:

There's three basic areas where errors are arising from. I Put asterisks to the right of these lines:

>Let me know if you need to see more code if itll help.

the whole compile log would be useful too

You're trying to use classes before they are defined(I think)

If you upload all the files I could take a look at it.

Nine_Masquerade_ · Post by **Nine_Masquerade_** » Fri Jul 24, 2009 11:52 am

Thanks pspPea
I could email you the project... just pm me your email address.

EDIT
Is it cool if i send it to this address: somethingsweet2bad@yahoo.com ?

>Is it cool if i send it to this address: somethingsweet2bad@yahoo.com ?

sure, I don't know who would get it though AS ITS NOT MINE

I sent you a pm with my email address
just change -at- to @ and -dot- to .

or you could upload it to mediafire or some other free file hosting site and post the link here.
