What a silly mistake

Why?

EngFunc_SetOrigin doesn't just set the origin, it does some other stuff that the physics system needs. While changing pev_origin may work in some cases, the former is the safest bet.

Okay thanks!

I checked the code and as you probably figured by now, you did no such thing back then.

Again, if you checked the code you'd see I'm settings players' origin at plane's origin.

Again, i checked the code, just gave you an alternative solution that produces the same/similar result in a different way.

No need for these kind of responses when im only trying to help and you were also wrong to answer like that.

Anyway, did you make it ?

But I never edited my code?

What kind of response? What was I wrong about? I don't get it.

Nope, but I'm still working on it

You were talking to me like im some random spammer insisting that I didn't read even the code. While, in fact I read the code and in no point in it did you set the velocity like you said. That is where you were wrong.

It's off topic anyway. Just thought i should clarify.

I'm sorry if I offended you, didn't mean it that way

What velocity am I supposed to give the entity so it can keep going forever?

This makes the plane go in the wrong direction, it should go straight forward

PHP Code:


			
MakeAirPlane( )
{  
    new Float:fOrigin[ 3 ] = { 3734.9, -23.8, 3295.2 };
    new Float:fAngle[ 3 ] = { -20.5, -170.9, 0.0 };
    new Float:fVelocity[ 3 ];
    
    g_iAirPlaneEnt = create_entity( "info_target" );
    
    set_pev( g_iAirPlaneEnt, pev_classname, AIRPLANE_CLASSNAME );
    engfunc( EngFunc_SetModel, g_iAirPlaneEnt, g_iDataAirPlane[ AirPlane_Model ] );
    set_pev( g_iAirPlaneEnt, pev_solid, SOLID_BBOX );
    set_pev( g_iAirPlaneEnt, pev_movetype, MOVETYPE_FLY );
    engfunc( EngFunc_SetOrigin, g_iAirPlaneEnt, fOrigin );
    
    velocity_by_aim( g_iAirPlaneEnt, 2000, fVelocity );
    set_pev( g_iAirPlaneEnt, pev_velocity, fVelocity );
    
    fOrigin[ 2 ] -= 40.0;
    
    new szPlayers[ 32 ], iNum, iTempID;
    get_players( szPlayers, iNum, "ch" );
    
    for( new i; i < iNum; i++ )
    {
        iTempID = szPlayers[ i ];
        
        AttachPlayerToPlane( iTempID, fOrigin, fAngle, fVelocity );
    }
}

AttachPlayerToPlane( id, Float:fOrigin[ 3 ], Float:fAngle[ 3 ], Float:fVelocity[ 3 ] )
{
    set_user_rendering( id, kRenderFxGlowShell, 0, 0, 0, kRenderTransAlpha, 0 );
    
    engfunc( EngFunc_SetOrigin, id, fOrigin );
    set_pev( id, pev_angles, fAngle );
    set_pev( id, pev_fixangle, 1 );
    set_pev( id, pev_velocity, fVelocity );
    set_pev( id, pev_gravity, 0.000001 );
    set_pev( id, pev_maxspeed, 0.000001 );
    
    g_bIsPlayerInParachute[ id ] = false;
    g_bPlayerInPlane[ id ] = true;
}

With MOVETYPE_FLY the entity with velocity should move forever, untill killed.

Also velocity_by_aim should throw an error in your case, it's used to calculate the velocity in the direction the PLAYER is looking.

My stock to four random directions (Map must be de_mon)

PHP Code:


			
getRandomPlaneDirection(Float:fOrigin[3], Float:fAngle[3], Float:fVelocity[3])
{
    switch(random_num(0, 3))
    {
        case 0:
        {
            fOrigin[0] = 3983.9
            fOrigin[1] = -3983.9
            fOrigin[2] = 3931.9
            
            fAngle[0] = -0.6
            fAngle[1] = 133.5
            fAngle[2] = 0.0
            
            fVelocity[0] = -206.6
            fVelocity[1] = 217.2
            fVelocity[2] = -10.6
        }
        case 1:
        {
            fOrigin[0] = -3983.9
            fOrigin[1] = -3983.9
            fOrigin[2] = 3931.9
            
            fAngle[0] = -0.3
            fAngle[1] = 38.6
            fAngle[2] = 0.0
            
            fVelocity[0] = 234.3
            fVelocity[1] = 187.2
            fVelocity[2] = -5.1
        }
        case 2:
        {
            fOrigin[0] = -3279.9
            fOrigin[1] = 1975.9
            fOrigin[2] = 3931.9
            
            fAngle[0] = -0.2
            fAngle[1] = -36.3
            fAngle[2] = 0.0
            
            fVelocity[0] = 241.5
            fVelocity[1] = -177.8
            fVelocity[2] = -3.3
        }
        case 3:
        {
            fOrigin[0] = 3205.4
            fOrigin[1] = 2055.4
            fOrigin[2] = 3931.9
            
            fAngle[0] = -0.5
            fAngle[1] = -138.9
            fAngle[2] = 0.0
            
            fVelocity[0] = -226.0
            fVelocity[1] = -197.0
            fVelocity[2] = -9.1
        }
    }
}

So, at MakeAirPlane(), you should just do

PHP Code:


			
new Float:fOrigin[3], Float:fAngle[3], Float:fVelocity[3]
getRandomPlaneDirection(fOrigin, fAngle, fVelocity)

And it'll generate a direction.

So, what you needed to create the plane correctly was:

- Origin = Where the plane will be created
- Angle = The direction
- Velocity = To set the velocity, I used that code to get those vectors:

PHP Code:


			
#include <amxmodx>
#include <fakemeta>

#define PLUGIN "Print Point vector"
#define VERSION "1.0"
#define AUTHOR "author"

public plugin_init() 
{
    register_plugin(PLUGIN, VERSION, AUTHOR)
    
    register_clcmd("aa", "cmdPrint")
}

public cmdPrint(id)
{
    new Float:fOrigin[3], Float:fAngle[3], Float:fVelocity[3]
    pev(id, pev_origin, fOrigin)
    pev(id, pev_angles, fAngle)
    velocity_by_aim(id, 300, fVelocity) // 300 is the velocity.
    
    server_print("fOrigin[0] = %.1f^n^nfOrigin[1] = %.1f^n^nfOrigin[2] = %.1f", fOrigin[0], fOrigin[1], fOrigin[2])
    server_print("fAngle[0] = %.1f^n^nfAngle[1] = %.1f^n^nfAngle[2] = %.1f", fAngle[0], fAngle[1], fAngle[2])
    server_print("fVelocity[0] = %.1f^n^nfVelocity[1] = %.1f^n^nfVelocity[2] = %.1f", fVelocity[0], fVelocity[1], fVelocity[2])
}

I just used sv_gravity 0, gone to the sky and typed 'aa' on console and got all the point's vectors.

And what you needed to make players follow the plane:

- Set the same vectors but with some different stuff:

1. pev_fixangle = to fix the player's angle
2. Set gravity 0 = so the player can not fall.
3. Set maxspeed to 0 = so the player can not move while he's in the plane.

Also,

PHP Code:


			
get_players( szPlayers, iNum, "ch" )

You must use the 'a' flag too.

You should know that is possible players jump from the plane at the same time and be stuck with each other, you can avoid it by setting their solid type to SOLID_NOT and after some time from the plane's jump, you can set the default solid type back.

You can maybe set the plane's solid type to SOLID_NOT too, so he has immunity to stuck in something. Also, add a time to auto-drop players that didn't jump from the plane while he was flying through the sky and remove it.

This is what i'm doing here, you can take these or make your version based in what I said.
