Hey, I have imported a large .mdl file and whish to change the CollsionBox to a polygon CollsionBox so that it conforms to the model. I have some screen shots of what I've done but havn't got it working yet.

Maybe I have checked the wrong box?

or

Do I need to write a script file to activate the PolygonCollison?

Heres the source on it:

ACTION enemy_dummy {
my.shadow = on;
my.entity_type = 2;
my.enable_scan = on;
my.polygon = on;

WHILE (1) {
IF (my.hit_by_player == 1) {
my.move_x = player.move_x;
my.move_y = player.move_y;
my.move_z = player.move_z;

// move_mode = ignore_passable | glide; //replace c_move with these 2 lines in versions of gamestudio below 6.4
// ent_move(nullvector,my.move_x);
c_move(my,nullvector,my.move_x,use_aabb | ignore_passable | glide);


IF (player.animblend == blend || player.animblend < attack_a || my.animblend > attack_f) { my.hit_by_player = 0; }
}
IF (player.animblend >= stand && target_enemy == my && player_lock_on == 0) && (player.animblend < attack_a || player.animblend > attack_f) { target_enemy = null; }
IF (target_enemy == my && vec_dist(my.x,player.x) > 200) { target_enemy = null; }
wait(1);
}

}


}

Write a seperate acion for the model terrain to.

action Poly_on
{
my.polygon = on;
}

then asign it.

Okay ive added in a seperate action. Now It solves my player from floating to the top of the box. But, now the model is passable. What else do I need to include in the new action?

1) Remove my.polygon = on in the dummy action. This flag should only be set for non-moving entities, so just put it in the structure model action;

2)

Quote:

---

POLYGON
If this flag is set, the model entity's real shape is used for OBB collision detection. Otherwise, an oriented bounding box or ellipsoid is used.

---

So, you´d better try using c_move with OBB system. Also, check if you are not overriding the polycollision system somewhere. By default var enable_polycollision should be 1;

Hey, what i mean in the first part is exactly what it says: remove my.polygon = on in the action enemy_dummy, that flag should not be set in moving entities.
You dont need that flag in the player action.

What you need is too assign my.polygon = on in WED or by script with an action attached to the MDL structure you have.

Also, why are you using the old system AABB? Try the OBB system for collision using c_move and be sure that the model isnt passable.

Ah ok, the:

// move_mode = ignore_passable | glide; //replace c_move with these 2 lines in versions of gamestudio below 6.4
// ent_move(nullvector,my.move_x);

is commented out



and I havea new action like NEM's said to add:

action Poly_on
{
my.polygon = on;
my.shadow = on;
}

That is without the Polygon button checked in the engine, but still doesn't work, with the new action assigned to the Model

Sorry, you need to have this before any while calls in your actor action.


action my_player //etc

{
my.fat = on;
my.narrow = on;
wait(1);
c_setminmax(my);
my.passable = off;
my.enable_impact = on; and so on...
while(1)
{
do stuff...
}

Its all in the manual by the way..

I still haven't gotten it to work

ACTION enemy_dummy {
my.shadow = on;
my.entity_type = 2;
my.enable_scan = on;

my.fat = on;
my.narrow = on;
wait(1);
c_setminmax(my);
my.passable = off;
my.enable_impact = on;
my.polygon = on;

WHILE (1) {
IF (my.hit_by_player == 1) {
my.move_x = player.move_x;
my.move_y = player.move_y;
my.move_z = player.move_z;

// move_mode = ignore_passable | glide; //replace c_move with these 2 lines in versions of gamestudio below 6.4
// ent_move(nullvector,my.move_x);
c_move(my,nullvector,my.move_x,use_aabb | ignore_passable | glide);


IF (player.animblend == blend || player.animblend < attack_a || my.animblend > attack_f) { my.hit_by_player = 0; }
}
IF (player.animblend >= stand && target_enemy == my && player_lock_on == 0) && (player.animblend < attack_a || player.animblend > attack_f) { target_enemy = null; }
IF (target_enemy == my && vec_dist(my.x,player.x) > 200) { target_enemy = null; }
wait(1);
}





}

As I said in the other thread and as demiGod has suggested, you probably have to remove the 'use_aabb' flag in the c_move function.
By setting this flag you are disabling the new collision system.
