 Posted: Mon Jul 20, 2009 10:11 am Post subject: 2D draw methods/ Java -> C++ |
 |
|
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/tutorials/c/lesson04-2.htm
| Code: | #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("Image Display Program", 0, 1, 1);
#define printf pspDebugScreenPrintf
/* Exit callback */
int exit_callback(int arg1, int arg2, void *common) {
sceKernelExitGame();
return 0;
}
/* Callback thread */
int CallbackThread(SceSize args, void *argp) {
int cbid;
cbid = sceKernelCreateCallback("Exit Callback", exit_callback, NULL);
sceKernelRegisterExitCallback(cbid);
sceKernelSleepThreadCB();
return 0;
}
/* Sets up the callback thread and returns its thread id */
int SetupCallbacks(void) {
int thid = 0;
thid = sceKernelCreateThread("update_thread", CallbackThread, 0x11, 0xFA0, 0, 0);
if(thid >= 0) {
sceKernelStartThread(thid, 0, 0);
}
return thid;
}
int main() {
char buffer[200];
Image* ourImage;
pspDebugScreenInit();
SetupCallbacks();
initGraphics();
sprintf(buffer, "cylus.png");
ourImage = loadImage(buffer);
int x = 240;
int y = 136;
sceDisplayWaitVblankStart();
SceCtrlData pad;
while(1)
{
sceCtrlReadBufferPositive(&pad, 1);
if(pad.Buttons & PSP_CTRL_LEFT)
x--;
if(pad.Buttons & PSP_CTRL_RIGHT)
x++;
if(pad.Buttons & PSP_CTRL_UP)
y--;
if(pad.Buttons & PSP_CTRL_DOWN)
y++;
if(pad.Buttons & PSP_CTRL_TRIANGLE)
break;
blitAlphaImageToScreen(0 ,0 ,16 , 20, ourImage, x, y);
flipScreen();
}
sceKernelSleepThread();
return 0;
} |
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?

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: | public You(Applet myApplet)
{
code
} |
So in the Applet itself, when you declare the You object, you see:
In the java version "You" gets the character/blood images through myApplet like so:
| Code: | for(int i = 0; i < 8; i++)
{
img = myApplet.getImage(myApplet.getCodeBase(), "blood"+i+".png");
blood.add(img);
} |
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: | You::You(main m)
{
code
} |
so as to then call
| Code: | sprintf(buffer, "cylus.png");
ourImage = loadImage(buffer); |
and
| Code: | | blitAlphaImageToScreen(0 ,0 ,16 , 20, ourImage, x, y); |
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. |

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: | class You{
.
.
.
public:
You(){
for(int i = 0; i < 8; i++) {
char file[100];
sprintf(file, "blood%d.png", i);
Image img = loadImage(file);
blood.insert(img);
}
}
draw(int srcx ,int srcy ,int width, int height, Image *ourImage, int x, int y){
blitAlphaImageToScreen(srcx ,srcy ,width, height, ourImage, x, y);
}
.
.
.
};

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: |
for( int i = 0; i < 6; i++ )
{
sprintf(buffer, "cylus"+i+".png");
img = loadImage(buffer);
playerPics[i] = im;
} |
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 :) |

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: | | ArrayList<Image> flamethrower = new ArrayList<Image>(); |
yet for some reason when i try making an ArrayList of ArrayLists like this:
| Code: | | ArrayList<ArrayList<Image>> weapon = new ArrayList<ArrayList<Image>>(); |
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.

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. |

Hmm found something worth looking at.
I ran my java source through a java -> C++ translator and it changed the ArrayLists like this:
| Code: |
ArrayList<Image> flamethrower = new ArrayList<Image>(); |
is now
| Code: | | std::vector<Image*> flamethrower = std::vector<Image*>(); |
I am not too sure what this means. Could someone enlighten me? |

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.

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?

I don't know about eclipse, but why not try compiling it?

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. |

As I've said before, im not too adept in C++, and therefore i cannot figure out what i am doing wrong here :(. When i try to compile this test code i get these errors:

change main.c to main.cpp
and add -lstdc++ to LIBS in your makefile

Thanks for your continued help psPea.
I renamed main.c to main.cpp and added -lstdc++ to LIBS.
Now i get this error:
**** Build of configuration Default for project ITAWAS ****

EDIT 1:
For the heck of it, after making the changes i commented out the line where i construct the Rectangle and then tried compiling. Then i get these errors:

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 did some cleanup and reduced the errors as much as i could, but now i've got some i can't figure out. In all i have 9 classes and each are experiencing similar errors when i try to compile. So solving them in one class will help me solve the rest. Ill show You.h's errors:

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:

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.
