Hi. Could someone please explain how to get coordinates of rectangle the corpse lies in? I first tried to get EV_VEC_absmin and EV_VEC_absmax but seems it gives me coordinates of alive player (see first image). What I need is illustrated on the second image. White sparkle is player origin for dead player (z axis is shifted toward the ground), black ones are the points I need. Here is what I did.

PHP Code:

static Float:origin[3];
static Float:p1[3];
static Float:p2[3];
static Float:p3[3];
static Float:p4[3];

entity_get_vector(c, EV_VEC_origin, origin);
origin[2] -= 32.0;
p1 = origin;
p1[0] -= 16.0;
p2 = origin;
p2[0] += 16.0;
p3 = p1;
p3[1] += 64.0;
p4 = p2;
p4[1] += 64.0; 


It kinda works, but with no respect to the corpse's angle (see the third image). I tried to apply angle but unfortunately I have poor knowledge of vector algebra.

PHP Code:

get_coordinates(c)
{
    static Float:angles[3];

    ...
    entity_get_vector(c, EV_VEC_angles, angles);
    rotate_point(p1, angles[1]);
    ...
}

rotate_point(Float:origin[3], Float:angle)
{
    new Float:x;
    new Float:y;
    new Float:sin;
    new Float:cos;

    x = origin[0];
    y = origin[1];
    server_print("p [%f, %f, %f]", origin[0], origin[1], origin[2]);
    sin = floatsin(angle, degrees);
    cos = floatcos(angle, degrees);
    origin[0] = x * cos - y * sin;
    origin[1] = x * sin + y * cos;
    server_print("mod [%f, %f, %f]", origin[0], origin[1], origin[2]);
} 


The angle here is the second value for EV_VEC_angles vector as it seems the only value that changes over time. With this function I got completely different coordinates which are far from the original.

PHP Code:

p [452.202880, 2370.059814, -123.968750]
mod [-2408.280761, 147.831207, -123.968750] 


The formula I used was found on SO (Rotation in 2D).

Btw its not possible to rotate entity size due its limitations to only rectangle shapes..

I do not want to rotate corpses. I need coordinates of points of corpse's box according to angle the corpse lies on the ground, like you may see on the second image. I would be also happy if someone could advise on how to get corpse center (like stomach coordinates)

Looking at the code I do not see anything related to my problem. There are only corpse's origin and angles which I already have.

The first picture is correct. When a player dies the death animation is sent and the entity stops being solid. It’s max and mins does not change because if you want the model to be displayed properly it requires the max & mins to stay the same. You should provide more information of what you really want to accomplish so we can tell you what is the best way. Maybe creating a new entity & force a specific death animation would help you. But we can’t tell for sure if you are not telling us what’s your final goal.

My final goal is to allow player to revive another player while standing on that player's corpse. Original idea was to get 4 points to form rectangle and check whether position of the rescuer is inside the rectangle. For now I get corpse's origin and check distance between me and the corpse. My problem is corpse's origin is near legs (light point on image 2). I need it to be at the middle of the corpse.

why not just use distance <= 72 units which is the default player height? you're over-complicating it imo.

If you want to be specific you can get the BonePosition of the stomach using GetBonePosition function from the engine.

But the catch is you need an entity corpse that is server side, and not the default corpse because its client side...

Then you will be able to revive far enough from the corpse, even through the wall.

Luckily I already have one. Thank you, works great.

PHP Code:

engfunc(EngFunc_GetBonePosition, ent, 2, pelvis_origin, pelvis_angles);

Corpses will clip through walls anyway. For example with headshot animation while with the back on a wall. 90% of the body will be inside the wall or on the other side of it.
