Hi. again.

Does anyone know how I can check if an entity is seen by the camera?
I need this so I can turn off some dynamic lights not viewed by the camera. W/ that I can have more than 8 dynamic lights. woooo! O_O Thanks all

check for model presence with c_scan

cheers

rel_for_screen (VECTOR*, VIEW*);
Convert the vector's screen coordinates into xyz-coordinates of the given view. Contrary to vec_for_screen, the view angle and positions is not used in this calculation. Thus the resulting coordinates can be directly used for positioning a view entity. If the result is invalid - outside the screen - the command returns 0, otherwise a nonzero value.

Parameters:
VECTOR* screen position to be converted to 3D.
VIEW* view used for the conversion, must be VISIBLE.

Returns:
0 position is outside the view.
!= 0 position is inside the view

@tindust and flits

I tried both of your suggestions. It worked perfectly with my code Thanks for helping me out, I really appreciate it O_O

Here's another solution I found to work pretty well. Since turning the lights off can sometimes cause the lightrange to turn off while still in view, you need to make sure the range isn't visible...


Create a spherical model for your dynamic light. Scale this model to adjust it's range. Then in the code, have the lightrange meet the radius of the model:

Code:

---

// ACTION: dLight
// Skill1: Red 128
// Skill2: Green 128
// Skill3: Blue 128
ACTION dLight
{
    my.invisible = on;
    my.passable = on;
    my.red = my.skill1;
    my.green = my.skill2;
    my.blue = my.skill3;
    //
    wait(1);
    c_setMinMax(my);
    my.skill10 = (my.max_x - my.min_x)/2;
    //
    while(my)
    {
        if (my.clipped)
        {my.lightrange = 0;}
        else
        {my.lightrange = my.skill10;}
        //
        wait(1);
    }
}

EDIT: Might help to make it passable

This is....this is...... O_O
Thank you so much xXxGuitar511!!!

This is EXACTLY what I need hehehe

Although setting the 'invisible = on' didn't help (The model didn't emit light). But that's easy to fix.I'll just make it transparent and reset alpha to 0.

Thanks agaiiin!!!
