Hi all, I am new to gaming, so sorry if I am missing something very simple here. I am trying to design a 3d room. I have all the models set up with all the textures. I would like to use 1 free camera to navigate around freely, but also have the ability to move to a preconfigured position by pressing 1 through to 9. Has anyone done this before or could anyone advise me where I should be focusing my time.

Am I correct in thinking you can only have 1 free camera per map or can this be achieved by adding several free cameras to different entity’s?

Regards

Wayne

You can have several cameras in the level at the same time; however, the best solution would be to move the entity that controls the camera at one of your 9 predefined locations as soon as you press the 1...9 keys.

Cheers George, I have the code working now. I just need to work on rotating the camera when it moves to the set locations

That's even easier; just rotate the entity that controls the camera in the proper direction like this:

if (location == 1)
{
my_entity.pan = 150; // my_entity is the entity that controls the camera
}

it worked a treat. I have set it up a slight different way,

var rotation_speed = 20;
var camPos[6][6]; //camera settings, x,y,z, pan, roll, tilt

// Camera pos 1
camPos[0][0] = -282; //x
camPos[0][1] = -111; //y
camPos[0][2] = 116; //z
camPos[0][3] = 66; //camera pan
camPos[0][4] = 0; //camera roll
camPos[0][5] = -45; //camera tilt

// Camera pos 2
camPos[1][0] = -4; //x
camPos[1][1] = 66; //y
camPos[1][2] = -61; //z
camPos[1][3] = 88; //camera pan
camPos[1][4] = 0; //camera roll
camPos[1][5] = -37; //camera tilt

// Camera pos 3
camPos[2][0] = 150; //x
camPos[2][1] = 150; //y
camPos[2][2] = 150; //z
camPos[2][3] = 0; //camera pan
camPos[2][4] = 0; //camera roll
camPos[2][5] = 0; //camera tilt

// Camera pos 4
camPos[3][0] = 150; //x
camPos[3][1] = 100; //y
camPos[3][2] = 70; //z
camPos[3][3] = 0; //camera pan
camPos[3][4] = 0; //camera roll
camPos[3][5] = 0; //camera tilt

// Camera pos 5
camPos[4][0] = 150; //x
camPos[4][1] = 20; //y
camPos[4][2] = 0; //z
camPos[4][3] = 0; //camera pan
camPos[4][4] = 0; //camera roll
camPos[4][5] = 0; //camera tilt

// Camera pos 6
camPos[5][0] = -70; //x
camPos[5][1] = 150; //y
camPos[5][2] = 300; //z
camPos[5][3] = 0; //camera pan
camPos[5][4] = 0; //camera roll
camPos[5][5] = 0; //camera til471t

// main game loop
while(1)
{

if ((7 >= key_lastpressed)&(key_lastpressed > 0))// if the [1 to 6] key is pressed
{
if (camera.x > camPos[key_lastpressed - 2][0]) camera.x -= 1 * time_step;
else if (camera.x < camPos[key_lastpressed - 2][0]) camera.x += 1 * time_step;
if (camera.y > camPos[key_lastpressed - 2][1]) camera.y -= 1 * time_step;
else if (camera.y < camPos[key_lastpressed - 2][1]) camera.y += 1 * time_step;
if (camera.z > camPos[key_lastpressed - 2][2]) camera.z -= 1 * time_step;
else if (camera.z < camPos[key_lastpressed - 2][2]) camera.z += 1 * time_step;
if (camera.pan > camPos[key_lastpressed -2][3]) camera.pan -= 1 * time_step;
else if (camera.pan < camPos[key_lastpressed -2][3]) camera.pan += 1 * time_step;
if (camera.roll > camPos[key_lastpressed -2][4]) camera.roll -= 1 * time_step;
else if (camera.roll < camPos[key_lastpressed -2][4]) camera.roll += 1 * time_step;
if (camera.tilt > camPos[key_lastpressed -2][5]) camera.tilt -= 1 * time_step;
else if (camera.tilt < camPos[key_lastpressed -2][5]) camera.tilt += 1 * time_step;


}

wait (1);
}

The next thing I am going to try and work on is reading the camera positions from an INI file. and also giving the user the option to store there own camera positions! Now the fun starts again.
