Hey Guys!

So im trying to finish my game here, but now a bug appeared..
The spritecollision is not working ...

Here's the code:

#include "DarkGDK.h"
#include "dinput.h"

char XPos[30];
char YPos[30];
char lol[5];

bool debug = false;
int level = 1;
int maxen = level * 2;
int speed = 1;
int score = 0;
int lvl1 = 10;
int lvl2 = 15;
int lvl3 = 20;
int lvl4 = 25;
int lvl5 = 34;
int lvl6 = 45;
int lvl7 = 68;

bool shooting = false;
char score1[10];
char highscore[100];

void GameOver()
{
		
	if (dbFileExist("hg//highscore.txt"))

	sprintf_s ( highscore, 20, "||Score: %d", score);
	
	dbOpenToWrite ( 1, "hg//highscore.txt" ) ;
	dbWriteString ( 1, highscore );
	}
	else
	{
		dbMakeFile("hg//highscore.txt");
		sprintf_s ( highscore, 20, "||Score: %d", score);

In

+ Code Snippet

void Movement()
{
	if(!dbSpriteExist(4))
	{
		
		int speed2 = speed;



		if(dbSpriteCollision(4, 1))
		{
			GameOver();
		}	
	}
}

if(!dbSpriteExist(4))
should be if(dbSpriteExist(4))

That's the first thing I saw.... There may be more.

The fastest code is the code never written.

Hi, could you give a bit more detail as to what isn't working. You check for collision for multiple sprites, does the collision not work anywhere or does it not work with specific sprites?

One other thing I saw was this:

+ Code Snippet

void collision()
{



	if(dbSpriteCollision(5, 4)) // bomba ao barco
	{
		dbDeleteSprite(5);
		dbDeleteSprite(4);
		score = score + 4 * level;
		
	}

if(dbSpriteCollision(6, 4)) // bomba ao barco
	{
		dbDeleteSprite(5);
		dbDeleteSprite(4);
		score = score + 4 * level;
		
	}

if(dbSpriteCollision(7, 4)) // bomba ao barco
	{
		dbDeleteSprite(5);
		dbDeleteSprite(4);
		score = score + 4 * level;
		
	}
if(dbSpriteCollision(8, 4)) // bomba ao barco
	{
		dbDeleteSprite(5);
		dbDeleteSprite(4);
		score = score + 4 * level;
		
	}

I don't know anything about the logic of your game so this may not be the problem but should the dbDeleteSprite(5) be changed to 6, 7 & 8 in the relevant if statments?

well, srry for not being specific xD

My game is like you have a headquarters

then there are pirates comming to your HQ.

You need to send bombs to the pirates.

Whats not working is the collision between the boat (4) and the player HQ (1)...

@EDIT:

Hey hey, old school wins again

I made this:

+ Code Snippet

void collision()
{

	// Test
		int BoatX = dbSpriteX(4);
		if (BoatX <= 123)
		{
			dbDeleteSprite(4);
			dbText(10, 70, "Lost");
		}
	//

It worked XD

No problem about the collision anymore... but if you can fix the problem it would be great.

This is the updated Code:

#include "DarkGDK.h"

int level = 1;

int score = 0;
int lvl1 = 10;
int lvl2 = 15;
int lvl3 = 20;
int lvl4 = 25;
int lvl5 = 34;
int lvl6 = 45;
int lvl7 = 68;

int player = 1;

bool shooting = false;
char score1[10];
char highscore[100];
