Hi, how can I make the entity to follow the player aim?
Like keeps following his aim, not just placing the entity where he aims

If someone can give me an example that would be nice

Subtract Look_Origin with entity_Origin normalize the outputs.
Multiple the outputs with the speed desired then set entity velocity to outputs

I reached that
PHP Code:
    new LookOrigin[3], EntityOrigin[3], szOutPut[3]
    
pev(idpev_originLookOrigin)
    
pev(pentpev_originEntityOrigin)

    
xs_vec_sub(LookOriginEntityOriginszOutPut
do I normalize like that?
PHP Code:
xs_vec_normalize(szOutPutszOutPut
And then how can I set the entity velocity?

PS> What im trying to do is to make fake entity for player to preview before he places the real one.
Should I use entity think, or only place those codes in fake entity function will be fine?

then you dont need to set velocity just simply set entity's origin where the player is aiming at.

Thank you
Used ham_entitythink

PHP Code:
new Float:LookOrigin[3];
get_user_hitpoint(idLookOrigin)

entity_set_origin(iEntLookOrigin)
drop_to_floor(iEnt)

// Get User HitPoint Stock

stock get_user_hitpoint(indexFloat:origin[3], maxdist=9999)
{
    new 
gunorigin[3], aimpoint[3];
    
get_user_origin(indexgunorigin1); // 1 - position from eyes (weapon aiming).
    
get_user_origin(indexaimpoint3); // 3 - end position from eyes (hit point for weapon).
    
if( get_distance(gunoriginaimpoint) > maxdist )
    {
        return 
0;
    }

    
IVecFVec(aimpointorigin);

    return 
1;
