guys.. can you help me..
i'm planning to highlight an entity when it was clicked and holds the entity to move by clicking any location.

function scan_ent()
{
if(event_type == EVENT_CLICK)
{
printf("Entity Detected!"); // testing part
}
}

action play_walk() //animation of "walk" for this entity
{
enable_mouse = 2;
my.emask |= ENABLE_CLICK;
my.event = scan_ent;

while(1)
{ walk_percent += 3*time_step ;
ent_animate(me,"walk",walk_percent,ANM_CYCLE);
wait(1);
}
}

function cursor() //enables the mouse;
{
mouse_mode = 2;
mouse_map = cursor_pcx;
mouse_range = 2000;
}

Does your code work? What's your question?

yes sir..

when i clicked the model.. it shows an prompt "Entity Detected".
i wanna know how to highlight the "edge" of the entity once it was clicked?

Guess you'll need a shader for that. Look at this one here:

Or you simply enlight the model by changing its brightness.

Good luck

maybe i'll choose to change the brightness of the model..

one question.. how do i remove the ambient of the model when i used this code:

vec_set(mat_model.ambient_blue,vector(255,0,0));
