Hi, what code i can do for positioning an entity in a position always relative to another entity, laso when the second entity is moving?

Something like that:

action keep_me_in_dist()
{
my.skill1 = handle(you); // get the pointer from somewhere
while(1)
{
you = ptr_for_handle(my.skill1);
vec_set(my.skill2,vector(20,33,5)); // play with these values
vec_rotate(my.skill2,you.pan);
vec_add(my.x,my.skill2);
wait(1);
}
}

The offset is depended from the "another" entities angle; if you dont want that, remove the vec_rotate.

thanks, but i don't understand very well the code, can you explain it me?

Well, look up the single functions in the almighty manual, there they are explained very well.

thanks again

Look, this is the code I`m using for attaching a gun to my model.

STRING Gatlin_mdl = "Gatlin.mdl";
function Gatlin()

{
proc_mode = PROC_LATE;
set(my,PASSABLE); // the Gatlin shouldn't slow down the player
while (player == NULL){wait (1);}//wait ´till the player is created.
while(1)
{
vec_for_vertex (my.skill1, you, 1446);
vec_for_vertex (my.skill4, you, 1447); //vertex on the model hand


vec_diff (my.skill7, my.skill4, my.skill1);// compute the vector that will be used by the Gatlin
vec_to_angle (my.pan, my.skill7); // rotate the Gatlin accordingly

// put the origin of the Gatlin in the vertex that is placed at the bottom of the arm
vec_set (my.x, my.skill1);
wait (1);
}
}


AND you need to add a line on the character code, to ent_create the model to attach and call the function.
BUT, this is going to attach the models nicely, but it can cause some issues depending on your player`s code.

thanks, i haven't problem because i use the physics engine, then i put the another entity as passable and there won´t be problems
