Currently I have, thanks to all that have helped me, code that enables me to rotate an entity via LMB click-drag. Here's the code I am using:
action rotate()
{
while(1)
{
if (mouse_left){
my.pan += mouse_force.x;
my.tilt += mouse_force.y;
}
wait(1);
}
}
Now what I would like to do is add a means to click some buttons and go to a particular view of that model. In other words, I would like to have buttons that read: - front - back - side - top - Bottom So I would need five buttons and clicking on one would snap the model to that view. I think this could be done in two ways: Moving the actual modelIn this, the code would instantly rotate the model to face the camera depending on which button was pressed. Setting up 5 cameras/positions and moving to the appropriate viewIn this, a click on a button would switch the view to a preset camera/position. I would set up five cameras (front, back, side, top and bottom) and clicking the back button, for example, would switch to that position. Now, I have the base idea, but am lost about how to implement it. Does anyone have any pointers? Thanks in advance. <edit> Doing it via the camera/position is preferred now that I think about it, though doing it both ways would teach me more. Thanks again.

front -> my.pan=0 my.tilt=0
back -> my.pan=180 my.tilt=0
side -> my.pan=90 my.tilt=0
top -> my.pan=0 my.tilt=-90
bottom-> my.pan=0 my.tilt=90

Doing it via the camera/position is preferred Then you should move the camera instead of rotating the model. The following code should give you a good start:
BMAP* bmp_view_button1 = "filename here";
...
void view_button(var num) {
if(player) {
switch(num) {
case 1:
vec_set(player.pan,vector(180,0,0)); // front
break;
case 2:
vec_set(player.pan,vector(0,0,0)); // back
break;
case 3:
vec_set(player.pan,vector(90,0,0)); // side
break;
case 4:
vec_set(player.pan,vector(0,90,0)); // top
break;
case 5:
vec_set(player.pan,vector(0,-90,0)); // bottom
}
}
}
PANEL* pnl_view_buttons = {
button(0,0,bmp_view_button1,bmp_view_button1,bmp_view_button1,view_button,NULL,NULL);
...
button(0,4 * your button height,bmp_view_button5,bmp_view_button5,bmp_view_button5,view_button,NULL,NULL);
flags = SHOW;
}
action rotate()
{
player = me;
mouse_mode = 1;
while(1)
{
if (mouse_left){
my.pan += mouse_force.x;
my.tilt += mouse_force.y;
}
vec_set(mouse_pos,mouse_cursor);
wait(1);
}
}
I've assumed that your camera is at 0,0,0 and your model is in front of the camera, that means its position is x,0,0 (in WED).

Thanks Superku! That gave me just what I needed! Here's my working code:
//Rotate View Around Object Test
//Images
BMAP* top_view_button = "top_button.jpg";
BMAP* bottom_view_button = "bottom_button.jpg";
BMAP* front_view_button = "front_button.jpg";
BMAP* back_view_button = "back_button.jpg";
BMAP* side_view_button = "side_button.jpg";
//View Button
void view_button(var num) {
if(player){
switch(num){
case 1:
vec_set(player.pan,vector(0,90,0)); //top view
break;
case 2:
vec_set(player.pan,vector(0,-90,0)); //bottom view
break;
case 3:
vec_set(player.pan,vector(180,0,0)); //front view
break;
case 4:
vec_set(player.pan,vector(0,0,0)); //back view
break;
case 5:
vec_set(player.pan,vector(90,0,0)); //side view
break;
}
}
}
//Panel
PANEL* buttons = {
button(0,0,top_view_button,top_view_button,top_view_button,view_button,null,null);
button(94,0,bottom_view_button,bottom_view_button,bottom_view_button,view_button,null,null);
button(188,0,front_view_button,front_view_button,front_view_button,view_button,null,null);
button(282,0,back_view_button,back_view_button,back_view_button,view_button,null,null);
button(376,0,side_view_button,side_view_button,side_view_button,view_button,null,null);
Flags = SHOW;
}
//Rotate Action
action rotate()
{
player = me;
mouse_mode = 1;
while(1)
{
if (mouse_left){
my.pan += mouse_force.x; // mouse movement changes PAN
//my.pan = clamp(my.pan,-189,189);
my.tilt += mouse_force.y; // mouse movement changes TILT
//my.tilt = clamp(my.tilt,-89,89);
}
vec_set(mouse_pos,mouse_cursor);
wait(1);
}
}
I'll play with mouse overs and all that later. I am just happy to have working buttons that do what I want them to. This opens up a lot of things to me. Thanks again!

How did you set up the view? IF it's like
camera.x = player.x + 200 * cos blah blah blah
Then swap the 200 for
var dist = 200;// im a global var
camera.x = player.x + dist
Then allow dist to be changed by anything, say the mouse wheel.
---------------------
There is no signature here.

Simply modify your view_button function and add more states (that is cases in the switch branch). There you could change the x-distance of the player to the camera. Example:
BMAP* close_button = "far_button.jpg";
case 6: // close
player.x = 50;
break;
case 7: // normal
player.x = 100;
break;
case 8: // far
player.x = 150;
break;
...
button(376,0,side_view_button,side_view_button,side_view_button,view_button,null,null);
button(xxx,0,close_button,....

Hi Superku,
Right, I figured that, but did not know the command. However, I don't have a "player" but just a POSITION that I set in WED. Do I have to set up a player (since it will never walk around)? Or can I move the actual POSITION item via code?
<edit>
Never mind. It works. Very simple. And that was what I was looking for.
Thanks.
