In the Lite-C Workshop 15 tutorial, you learn how to write code to control the camera using the joystick. In the Lite-C Workshop 18 tutorial, you learn how to write code to control the car using the keyboard. I modified the code so that I can move the car forward and backward using the keyboard. How do I control the car using joystick?

Code:

---

action my_car()
{
	while (1)
	{	
		if (key_a && key_cuu)
			my.pan += 3*time_step;
		if (key_s && key_cuu)
			my.pan -= 3*time_step;
		if (key_a && key_cud)
			my.pan -= 3*time_step;
		if (key_s && key_cud)
			my.pan += 3*time_step;
		if (key_cuu)
			c_move (my, vector(15*time_step, 0, 0), nullvector, GLIDE);
		if (key_cud)
			c_move (my, vector(-15*time_step, 0, 0), nullvector, GLIDE);
		wait (1);
	}
}

I'm not sure if this is the right way to use c_move and joy_force commands to move the car. Is it possible to attach the camera to the car and move them together?

Code:

---

action my_car()
{
	while (1)
	{	
		if (joy_force.y>0)
		  my.pan -= joy_force.x*time_step;
		if (joy_force.y<0)
		  my.pan += joy_force.x*time_step;
		if (joy_force.y>0)
			c_move (my, vector(15*time_step, 0, 0), nullvector, GLIDE);
		if (joy_force.y<0)
			c_move (my, vector(-15*time_step, 0, 0), nullvector, GLIDE);
		wait (1);
	}
}

For joystick control, you may try the following code :

Code:

---

var speed = 5;  // play with 5
var jForce;
action my_car()
{
   while(1)
   {
      jForce = (joy_6 - joy_5);
      // move forward and backward
      c_move(my,vector((joy_6-joy_5)*speed*time_step,0,0),nullvector,GLIDE);
      // turn left and right
      c_rotate(my,vector(-joy_force.x*time_step*jForce,0,0),USE_AXIS);

      // follow cam
      vec_set(camera.x,vector(-200,0,40));  // play with the vec position
      vec_rotate(camera.x,my.pan);
      vec_add(camera.x,my.x);
  
      //camera.pan += 0.2 * ang (my.pan - camera.pan) * time_step; // line A
		
      vec_set(camera.pan,my.pan);   // line B

      wait(1);
   }
}

If you want a little bit camera lag uncomment line A and comment out line B.
My joystick may not the same as yours, try to modify those joy_???? youself.

Have fun!

Vlau, Can you modify your joystick code so that pressing the triggers on XBOX 360 controller moves the car? If that's not possible, use the Y axis on the left thumbstick to move the car?

I don't have XBOX360 so I can't test it for you.
Actually, you're free to modify the above code
yourself and it is very easy.

There are many buttons available such as :
joy_1...12, joy2_1...12 joy_buttons...etc.
They are all described well in the manual.

On my XBOX360 gamepad, the triggers use Z Axis and the right thumbstick (joystick) uses X Rotation and Y Rotation. Does Game Studio A7 support XBOX360 gamepads? If so, how do I set up Game Studio programs for XBOX360 gamepads?

Maybe this thread could help.

vlau, Thanks for the plug-in for XBOX360 gamepad support. The plug-in was written for A6 and I think that it needs to be updated for A7. I couldn't compile the Xbox_dll.wdl file because the "define" command was an undeclared identifier.

I think that the plug-in for XBOX360 gamepad support is not compatible with A7. After compiling the game level that includes the plug-in for XBOX360 gamepad support and trying to run the game level, I get the Microsoft send/don't send message.
