Need help, C++ game
Well this is for a class, I don't have any more help room hours, I don't know anyone that is decent at programming that could help me, so sort of a last effort here.
I am getting to the point where the user enters in a power value, and that is happening alright, but the repaint() function is not working for some reason, and when I call it, it gives me a error code 128 in my compiler. (I think I am using a g++ compiler...I dunno how to tell really)
Anyways, here is the main.cxx
#include <winbgim.h>
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <iomanip>
#include <fstream>
#include <string>
//#includes for the other classes
#include "constants.h"
#include "ground.h"
#include "tank.h"
//make control panel -- picture done, need it to be displayed when help button is pressed
//make new terrain files (diffuculty for each) -- using flat for testing, will make others once it works
//ready to play screen, pick level -- will make a picture screen and have different levels corrospond to different numbers
//winner screen -- pictures done, displayed when a tank gets hit
//make reset functions
using namespace std;
void getAngle (int mouseX, int mouseY, int tankY, int tankLeft, int tankRight, int slopeX, int slopeY);
void repaint (bool quitHit, bool helpHit, bool resetHit, Tank player1, Tank player2, Ground floor, bool turn_one);
bool nearby (int x, int y, int width, int height, int mouseX, int mouseY);

slopeY = (tankY - mouseY); //the Y value of slope
}
Any help would be appreciated. It isn't getting to any of the cout statements in the repaint() function though.
If you need the other parts of the program to actually run and test it, hit me up on AIM, phait10101. Or irc.gamesurge.net as patcollins.
