Simple Camera - 02/22/09 07:33

I hate to start off with such an ignorant question but I am working on a level, I added a camera and I pan and tilt it with this code:

Code:

 if (key_w) camera.tilt += 2 * time_step; 
      if (key_s) camera.tilt -= 2 * time_step; 
      if (key_a) camera.pan += 2 * time_step;
      if (key_d) camera.pan -= 2 * time_step;

Any simple way to make that camera zoom around the map with the W, A, S, D keys? Basically just need to be able to walk-thru the level, however collision would be nice, I am tooling around with c_move as we speak, but still relatively new to the whole process.

What exactly do you want to alter with this WASD keys?
The rotation of the camera (as in your snippet) or the position of it?
Do you have a player model and action which moves through the level?

add your code in main function in while cycle

Just add to the code you are using, if you use the WASD keys for movement you will have to use other keys(or the mouse) for tilting and panning:

Add to main:

while(1)
{
// Tilting and panning code here

if (key_w) camera.x += 2 * time_step; // Adjust 2 factor for right speed!
if (key_s) camera.x -= 2 * time_step;
if (key_d) camera.y += 2 * time_step;
if (key_a) camera.y -= 2 * time_step;

wait(1);
}

I am kicking myself for not even thinking about the axis call of the camera.. lol, thanks!

Just FYI, I put the camera code in it's own thread, it's awesome!

Here is a fully functional camera, if anyone ever needs it.

Code:

void camera_move()
{
	while (1)
   {
   	if (key_q) camera.pan += 10 * time_step;
      if (key_e) camera.pan -= 10 * time_step;
      if (key_z) camera.tilt += 10 * time_step;
      if (key_c) camera.tilt -= 10 * time_step;
   	if (key_w) camera.x += 10 * time_step;
		if (key_s) camera.x -= 10 * time_step;
		if (key_d) camera.y += 10 * time_step; 
		if (key_a) camera.y -= 10 * time_step; 
		if (19 == key_lastpressed) // R key will reset the pan and tilt to 0.
      {
         camera.pan = 0;
         camera.tilt = 0;
      }   
   wait (1);
   } 
}
