Ive been working on this all day, Im stumped! For some reason whenever I start the engine, my model, a car, starts to move backwards very slowly. Everything else works as normal. I cant figure out the reason for this strange backwards movement, any help would be appreciated.

Code:

var video_mode = 7; // 800x600 pixels
var video_depth = 32; // 32 bit mode

////////////////////////////////////////////////////////////////////////////////////

string homework18_wmb = <homework18.wmb>; 

ENTITY* car;

bmap bmpSpeed = "speedometer.bmp";

////////////////////////////////////////////////////////////////////////////////////

var accel = 1; //acceleration
var reverse = -1; //reverse acceleration
var absSpeed = 1; //universal speed, to be displayed by the speedometer negative numbers are reverse for now

function main()
{
	fps_max = 30;
	level_load (homework18_wmb);
	wait (3);
	while(1) //set up the camera
	{
		camera.x = car.x; 
		camera.y = car.y - 300;
		camera.z = car.z + 1000;
		camera.pan = 90; // set the correct orientation for the camera
		camera.tilt = -68; // using its pan and tilt angles
		
		wait(1);
	}
}

panel speedometer
{
	pos_x = 0;
	pos_y = 0;
	layer = 1;
	bmap =  bmpSpeed;
	digits(35,45,3,_a4font,1,absSpeed);
	flags = overlay, visible;
}

action my_car
{
	car = me;
	my.fat = on; 
	my.narrow = on; 
	c_setminmax(my); 
	while (1)
	{
		// move the car using relative_speed
		if (key_a == on)  //pans the car, but only if moving
		{	
			if(accel != 0)
			{
				my.pan += 5; // increase the pan angle of the car
			}
			if(reverse != 0)
			{
				my.pan += 5; // decrease the pan angle of the car
			}
		}
		
		if (key_d == on) //pans the car, but only if moving 
		{

				my.pan -= 5; // decrease the pan angle of the car

		}
		
		if (key_w == on) //while pressing w...
		{	
			accel += 1;	  //accelerate by increasing the x value...

			{
				accel = 40;
			}
			if(accel >= 1)			  //set up the value for the speedometer to display
			{
				absSpeed = accel;   //speedometer value == accel
			}
		}
		
		if(key_w == off)          //if you let off on the gas...
		{
			accel -= .5;           //decelerate
			c_move(my,vector(accel,0,0),nullvector,glide);
			if(accel <= 1)         //stop decelerating when not moving
			{
				accel = 0;
			}
			if(accel >= 1)				//set up values for speedometer
			{
				absSpeed = accel;
			}
		}
		
		if(key_s == on)           //when hitting reverse
		{
			c_move(my,vector(reverse,0,0), nullvector, glide); //decrease x value	
			reverse -= 1;          		 							   //in this vector to back up
			if(reverse < -18)
			{
				reverse = -18;
			}
			if(accel <= 1)						//set up values for speedometer
			{
				absSpeed = reverse;	
			}
		}
		
		if(key_s == off)             //when you let off on the gas
		{
			c_move(my,vector(reverse,0,0),nullvector,glide);  //slow down
			reverse += 1;
			if(reverse >= -1)
			{
				reverse = 0;
			}

			}
		}
		
		if(key_space == on) //brakes
		{

			{
				accel -= 2.5;
			}
			if(reverse < 0)
			{
				reverse += 2.5;

		}

This is some modified and reworked code from the c-script tutorial, Im new to Gamestudio. Im using Gamestudio trial version 6.40.5. Thanks
