Snake & Ladder Game in C (TurboC++ Compiler)
This game was developed for students who are developing mini project with the help of TurboC / C++ compiler. In my previous tips, I have explained how to create a splash screen with TurboC compiler. So those who are downloading this program should go through the previous tip explained here -> Splash Screen.
Game Mode
- Single Mode: In this mode: "Player 1" -> User and "Player 2" -> Computer
- Double Mode: Two players can play with the dice
Game Rules & Functions
- Throwing Dice: This is done by pressing the left button on "Player 1". The counter is stopped when you release the button and the counter value is displayed on the Dice.
- If player gets number six after throwing the dice, then the respective player is eligible for one more throw.
User Interface & Mouse Click Events
For user interface design ideas, please go through the previous tip explained here -> Splash Screen. User Interface was designed with the help of basic setfillstyle, floodfill, rectangle and bar functions. In this tip / tutorial, I will explain how to use mouse events and handle them nicely.
Graphics mode is initialized and then mouse is activated by calling initmouse() function. We are using ax register to store the values and then raising interrupts for activating mouse. After calling this function, we need to call show showmouseptr(). We need to call this function if we done any change in interface. Mouse pointer can be hidden by using hidemouseptr() function. This function will be frequently used if we are drawing with Mouse Pointer. We can also get the mouse position (xy) cordinates by using or calling this function getmousepos(). The first parameter in this getmousepos function is the button click option. The button pointer is assigned to 1 if "Left" button clicked and 2 if "Right" button is clicked.
union REGS i,o;
void initmouse()
{
i.x.ax=0;
int86(0x33,&i,&o);
}
void showmouseptr()
{
i.x.ax=1;
int86(0x33,&i,&o);
}
void hidemouseptr()
{
i.x.ax=2;
int86(0x33,&i,&o);
}
Get Mouse Position Button 1-> Left and Button 2-> Right.
void getmousepos(int *button,int *x,int *y)
{
i.x.ax=3;
int86(0x33,&i,&o);
*button=o.x.bx;
*x=o.x.cx;
*y=o.x.dx;
}
Restricting Mouse pointer in respective closed window:
void restrictmouseptr(int x1,int y1,int x2,int y2)
{
i.x.ax=7;
i.x.cx=x1;
i.x.dx=x2;
int86(0x33,&i,&o);
i.x.ax=8;
i.x.cx=y1;
i.x.dx=y2;
int86(0x33,&i,&o);
}
Shadow Effect
Shadows effect was created by using outtext. To get the effect, it's needed to print the same text twice, one in grey color (shadow) and the original text on top by moving left.
Splash and Snake Picture
Splash screen was created with Rectangle function. The snake picture was drawn with LineTo function and the color was done with Fill Patterns.
Game Board
Game board was designed with Lineto, Floodfill and Outtext function. Snake was drawn with continuous ellipse function with fill pattern style.
