Help with logic..

[bconnor]

So basically im trying to work on a single player pong game ...

What im struggling with the logic behind the movement of the paddle..

If i just keep pressing the one direction, say a ... that moves fine, though the issue arises when i than press z, rather than moving down just one space, it moves far more than that...

	

/* a = up, z = down */


	int	c, temp, moveA, moveZ;
	temp = 1; 
	moveA, moveZ = 5; 
	
	set_up();

	while ( ( c = getchar()) != 'q' ){
		if ( c == 'a' ){
		clear();
		attron(A_REVERSE);
	
		move(0,LEFT_EDGE+20);
		addstr(" Single Player Pong ");	
	
		move(2,LEFT_EDGE+2);
		addstr(" INSTRUCTIONS: (move paddle) A - up, Z - down (quit) - q ");
	
	
		move(TOP_ROW-1,LEFT_EDGE-1);           	
		hline(' ', LEFT_EDGE + 53);		/* Top Border */
		vline(' ', TOP_ROW + 13);		/*  Left Side  */
	
		move(BOT_ROW+1,LEFT_EDGE); 	  	/* Bottom Border */
		hline(' ', LEFT_EDGE + 52);
		
		moveA = (TOP_ROW + 5)-temp;
		move(moveA,RIGHT_EDGE+1);		  
		vline(' ', (BOT_ROW-TOP_ROW)/3);
		attroff(A_REVERSE);
		getch();	
		if ( c == 'a' )	{
			temp++;
			}
		else {
			moveA = moveA +1;
			}
		}
		else if ( c == 'z' ){
		clear();
		attron(A_REVERSE);
	
		move(0,LEFT_EDGE+20);
		addstr(" Single Player Pong ");	
	
		move(2,LEFT_EDGE+2);
		addstr(" INSTRUCTIONS: (move paddle) A - up, Z - down (quit) - q ");
	
	
		move(TOP_ROW-1,LEFT_EDGE-1);           	
		hline(' ', LEFT_EDGE + 53);		/* Top Border */
		vline(' ', TOP_ROW + 13);		/*  Left Side  */
	
		move(BOT_ROW+1,LEFT_EDGE); 	  	/* Bottom Border */
		hline(' ', LEFT_EDGE + 52);
		
		moveZ = (TOP_ROW + 5)+ temp;
		move(moveZ,RIGHT_EDGE+1);	  
		vline(' ', (BOT_ROW-TOP_ROW)/3);
		attroff(A_REVERSE);
		getch();
		if ( c == 'z' ){
			temp++;
			}
		else{
			moveZ = moveZ -1;
			}
		}

Make a function to handle movement. Pass it a value that indicates up or down. If up, use + 1, if down, use -1 (or whatever your movement increment is).
