My brother has sent me on a task to try and somewhat recreate mario brawl. Well, that is going to be hard, considering I am somewhat a noob, although I know many functions.

My one problem is how to make people jump. I have thought of one way, but it is extremely long......... Is there an easy way?

Also, Is there any random function in darkGDK? I think it is like dbRandom ( ); but I need to double check.

Lastly, Is there a time finction in darkGDK or c++? I know one way, but it isn't exact-- Like is there a code that sets one object to just wait for a couple of second and then do something?

I know it seems that I won't be able to do it, and that I should start out easier, but I can manage. One thing though, get ready to answer another question-- I might have more along the way.

1. What's the extremely long way? The jump code I use for my fighter is 16 lines per character...

2. If you didn't know there is a list of all commands... Start Menu->Programs->The Game Creators->Dark GDK->Documentation->Information... You can check for a random function there...

3. You could always set incrementing integer into your loop which when reaching a certain number does something...

1. My jump method actually proves to be faulty.

+ Code Snippet

if ( dbUpKey ( ) == 1 ){
	if ( JumpNumber == 0 ){
		dbPositionObject ( 6, dbObjectPositionX ( 6 ), dbObjectPositionY ( 6 ) + 10.0f, dbObjectPositionZ ( ) );
		JumpNumber == 25;}
}
if ( JumpNumber > 0 ){
	dbMoveObjectDown ( 6, 1.0f );
	JumpNumber = JumpNumber - 1;}

.... Whats yours? Mine is a little messy....

2. Thanks, didn't know that!

3. Thats the way I know... I was hoping there was another...

Its not about what you know, its about how you figure it out.

1. Mine isn't very clean at all, it's actually quite messy... I'm in no way an experienced programmer... I'll post but I use quite a few booleans to make it work so I'm not sure if you'll understand it...

+ Code Snippet

if (dbJoystickUp ())
	
		{ {if (( !dbObjectPlaying ( 2 ) ) && ( !dbObjectFrame ( 2 ) ) > 41 < 55)
		dbPlayObject ( 2, 42, 54 );}
		{if (D_BlockProper)
			dbPrint ("NULL");
		else
		if ((dbObjectPositionY (2)) > 11)
		{DwarfGoingUp=false; DwarfGoingDown=true;}
		else
		if ((dbObjectPositionY (2)) < 1)
		{DwarfGoingDown=false; DwarfGoingUp=true;}
		if ((DwarfGoingDown) && (!DwarfGoingUp) && (!D_BlockProper))
		{dbMoveObjectDown (2, 0.6);}
		else
		if ((DwarfGoingUp) && (!DwarfGoingDown) && (!D_BlockProper))
		{dbMoveObjectUp (2, 0.6);}}
		}
}
{if (!dbJoystickUp ())
		{if ((dbObjectPositionY (2)) < 11.6 && (dbObjectPositionY (2)) > -1)
		{if ((dbObjectPositionY (2)) < 4.2)
		{dbPositionObject (2, dbObjectPositionX (2), -2.25, dbObjectPositionZ (2));}
		else
		if ((dbObjectPositionY (2)) > 4.2)
		{dbPositionObject (2, dbObjectPositionX (2), -2.25, dbObjectPositionZ (2));}
		}
		}
}

2. That file will prove to be invaluable... keep it handy...

3. I don't DGDK has it's own timer but there is probably one included in some library that came with C++... Search around and you might find the command...

Try dbTimer()

It's used in both of the game examples, 2d and 3d.

I don't need an oven to make my cookies.

Yeah, I understand it, I am a noob at c++ but not at programming, I was doing python before this, and I used a lot of those!-- boolians--

Once again thanks for the help!

I have CLOCK class and Timer class you can rip from my library: http://code.google.com/p/darkgdkoop/

@Jason: Could you partially program in OOP while doing the rest in procedural, seeing as there is timer class...

@programing maniac: I didn't mean you didn't know what booleans were, I was just saying since I didn't include all the code overhead and what the booleans were there for might not make sense...

Absolutely

test.cpp

+ Code Snippet

#include <DarkGDK.h>
#include "jgc_clock.h"
#include "jgc_timer.h"

void DarkGDK ( void ){ 
  JGC_CLOCK *Clock = new JGC_CLOCK();
  int DelayInMilliSec = 200;
  JGC_TIMER *Timer = new JGC_TIMER(); 
  Timer->Set(DelayInMilliSec, Clock->Time_New);

  while ( LoopGDK ( ) ){
    Clock->Update();
    dbCLS();
    if(Timer->DelayPassed(Clock->Time_New)){
      dbPrint("Hi Mom");
    }; 
    
    dbSync();
  };
  delete Timer;
  delete Clock;
};

Something like that should work.

jgc_clock.h
