hello everyone,

I'm trying to get origins around an origin to create a beam between center and the end of the circle
and I'm not really good at math lol.
for example origin would be {0.0,0.0,0.0} which would be the center, and the distance would be 150.0

so I want to make it start from the top of it, and make it go in circular motion by 360°

any snippet for it?

probably by using floatsin() and floatcos()? I have no idea how to use them

thanks in advance!

Figured it out! here's a lil snippet if anyone needs it:

PHP Code:

stock get_circular_origin(Float:angle, Float:origin[3], Float:radius,Float:COrigin[3])
{
       COrigin[0] = radius * floatcos(angle,degrees);
       COrigin[1] = origin[1]
       COrigin[2] = radius * floatsin(angle,degrees);
}

This Can Help u

PHP Code:

new Float:g_vec[3] = {25.0, 0.0, -20.0}
new Float:g_deg = 0;

public fxWindFX( Client )
{    
       set_task(0.05, "rotate", Client, _, _, "b", 1);
 
       set_task(1.0, "fxRestore", Client, _, _, "b", 1);
}
public fxRestore( Client )
{
        g_vec[0] = 25.0;
        g_vec[1] = 0.0;
        g_vec[2] = -20.0;
}
public rotate(Client)
{
    new Float:x, Float:y
    x = 25*floatcos(g_deg, degrees);
    y = 25*floatsin(g_deg, degrees);
    g_deg += 70;
    
    display(Client)
    
    g_vec[0] = x
    g_vec[1] = y
    g_vec[2] += 8.0;
}
public display(Client)
{
        new origin[3];

        get_user_origin(Client, origin)

        message_begin(MSG_PVS, SVC_TEMPENTITY, origin)
        write_byte(TE_SPRITE) // TE id
        write_coord(floatround(g_vec[0] + origin[0]) )
        write_coord(floatround(g_vec[1] + origin[1]) )
        write_coord(floatround(g_vec[2] + origin[2]) )
        write_short( engfunc( EngFunc_ModelIndex, "sprites/steam1.spr") );
        write_byte(3) // scale
        write_byte(255) // framerate
        message_end() 
}

Use find_location_around_origin in the first post.

totally unnecessary and poorly optimized for what he needs.

He didn't explain properly and its not poorly optimized, rather more competent, that isnt the thing he needed.

and FFS don't use grey color as the font color it makes it difficult to be read.

sorry for the late response everyone, thank you @XSlayer and @Natsheh for the help!

I used gray color cause I meant to show that I solved the problem.
what I was trying to do is create an entity that would rotate horizontally or vertically around the player and keeping it at the same direction even if the player turns around.

I ended up with these lines which did what I needed:

PHP Code:

static Float:VicOrigin[3], Float:EntOrigin[3]

    pev(ent, pev_origin, EntOrigin)
    pev(victim, pev_origin, VicOrigin)
    VicOrigin[0] = VicOrigin[0]+(200.0 * floatcos(ang,degrees));
    VicOrigin[2] = VicOrigin[2]+(200.0 * floatsin(ang,degrees));
    set_pev(ent,pev_origin,VicOrigin); 


and I used pev_origin for a reason instead of pev_velocity
