C is Fun
C - may be it is first character for computer students. Ever since I learned it, I've liked it, loved it.
Here is a game source code I wanna share . . .
I like linux but I've done my coding on and for windows XP because I found graphics.h as the easiest header I can work on.
I call this 1 as Pushbox.
Explanation :
Here I have created 11 row and 9 col char matrix which actually acts as platform for the puzzle.
To differentiate all the elements different characters are used.
H for wall
O as moving object or "Hero"
U as the object that has to pushed by hero
X as the hurdles , U must be pushed into X
a as empty spaces.
Placing Walls, Moving objects U, hurdles X and empty spaces along with the initial place of "Hero" is covered in designing part.
You can customize your own puzzle by changing the Array elements accordingly.
Rules:
- Movement of Hero is done by using keys w as up, a as left, s as down, d as right.
- Hero is restricted through walls ans Xs.
- Hero can push only one object at a time.
- Remember only pushing is possible pulling is restricted
- When you push box in hurdles both the object and hurdles will disappear and the position acquired by X before pushing will become free space.
- At any stage to Quit press o.
- To restart press r.
- Play keeping caps lock off.
