The added codes are marked in red color, so it can be easy for you to spot them.

This is added:

Code:

set_ent_rendering(plr, kRenderFxGlowShell, 0, 150, 50, kRenderNormal, 3);

And this is added on multiple places:

Code:

set_ent_rendering(plr);

So, how can those errors be fixed? What causes them? I would like someone to explain this to me, so i can know how to fix them not only in this plugin, but in other plugins, too, if i get those errors.

Thanks.

Re: How to solve this "undefined symbol" error?

set_ent_rendering() is an AMX Mod X built-in function and is defined when you include engine.inc. You likely need to fix your setup. If you're not 1.9.0 or newer, you need to upgrade, it does not exist in 1.8.2.

Re: How to solve this "undefined symbol" error?

Upgrading Amxx is REQUIRED, as previously stated. Script was never intended for the passe Amxx 182. Through perseverance, glow is possible.

Code:

#if !defined set_ent_rendering
#define set_ent_rendering set_rendering
#endif

Yes, i still use AMXX 1.8.2. When i upgrade to 1.9, many plugins start showing many errors in the console. This is because my ZM mod uses plugins made during the AMXX 1.8.2 era and may not be compatible with newer versions of AMXX.

Method # 1: Define. (Just made this now.)

Code:

#if !defined set_ent_rendering
#define set_ent_rendering set_rendering
#endif

Method # 2: Stock. (Have used this for years.)

Code:

#if AMXX_VERSION_NUM == 182
stock set_ent_rendering(index, fx=kRenderFxNone, r=0, g=0, b=0, render=kRenderNormal, amount=16)
{
    set_pev(index, pev_renderfx, fx);
    new Float:RenderColor[3];
    RenderColor[0] = float(r);
    RenderColor[1] = float(g);
    RenderColor[2] = float(b);
    set_pev(index, pev_rendercolor, RenderColor);
    set_pev(index, pev_rendermode, render);
    set_pev(index, pev_renderamt, float(amount));
}
#endif

Compiled on Amxx 182 and tested on Amxx 110.

Code:

#include amxmodx
#include engine
#define iRcolor random(256)

#if !defined set_ent_rendering
#define set_ent_rendering set_rendering
#endif

public client_command(id)
{
    if(is_user_connected(id))
    {
        set_ent_rendering(id, kRenderFxGlowShell,  iRcolor,  iRcolor,  iRcolor, is_user_alive(id) ? kRenderGlow : kRenderNormal, 25);
    }
}

Let's complicate it slightly.

Code:

#include amxmodx
#include engine
#define iRcolor random(256)

#if !defined set_ent_rendering
#define set_ent_rendering set_rendering
#define native_whateverworks set_rendering
#endif

public client_command(id)
{
    if(is_user_connected(id))
    {
        native_whateverworks(id, kRenderFxGlowShell,  iRcolor,  iRcolor,  iRcolor, is_user_alive(id) ? kRenderGlow : kRenderNormal, 25);
    }
}

Furthermore, if using Re; rendering effects may not be possible according to several testimonials.

In other words, what i want to di is impossible if i don't upgrade the AMXX version to 1.9 or newer? There aren't alternative glow functions that work on AMXX 1.8.2? Okay, i will try to upgrade the version again.

Re: How to solve this "undefined symbol" error?

did you even read what he wrote? he just explained with examples what you have to do to make the glow effect to work

Thanks for the help. The first method (Define) works fine. Although i have compatibility issues between the glow function and the glow functions of other plugins, i know how to fix this by myself.

Now, i would like to know is what is the difference between the first and the second method and which method is better? And if the function doesn't exist in AMXX 1.8.2, how does the firts method solves the problem if it doesn't add new codes/functionalities?

EDIT:

If i use only this code:

Code:

#if !defined set_ent_rendering

#define set_ent_rendering set_rendering

#endif

...everything works fine.

But if i use this code:

Code:

#if AMXX_VERSION_NUM == 182

stock set_ent_rendering(index, fx=kRenderFxNone, r=0, g=0, b=0, render=kRenderNormal, amount=16)

{

    set_pev(index, pev_renderfx, fx);

    new Float:RenderColor[3];

    RenderColor[0] = float(r);

    RenderColor[1] = float(g);

    RenderColor[2] = float(b);

    set_pev(index, pev_rendercolor, RenderColor);

    set_pev(index, pev_rendermode, render);

    set_pev(index, pev_renderamt, float(amount));

}

#endif

...i get the following messages by the compiler:

zp43_gas_mask.sma(20) : error 017: undefined symbol "set_pev"
zp43_gas_mask.sma(20) : warning 215: expression has no effect
zp43_gas_mask.sma(20) : error 001: expected token: ";", but found ")"
zp43_gas_mask.sma(20) : error 029: invalid expression, assumed zero
zp43_gas_mask.sma(20) : fatal error 107: too many error messages on one line

If i combine both codes shown above, i get the following:

zp43_gas_mask.sma(22) : error 025: function heading differs from prototype
zp43_gas_mask.sma(23) : error 021: symbol already defined: "set_rendering"
zp43_gas_mask.sma(24) : error 017: undefined symbol "set_pev"
zp43_gas_mask.sma(24) : warning 215: expression has no effect
zp43_gas_mask.sma(24) : error 001: expected token: ";", but found ")"
zp43_gas_mask.sma(24) : error 029: invalid expression, assumed zero
zp43_gas_mask.sma(24) : fatal error 107: too many error messages on one line

If i use this code:

Code:

#include amxmodx

#include engine

#define iRcolor random(256)



#if !defined set_ent_rendering

#define set_ent_rendering set_rendering

#endif



public client_command(id)

{

    if(is_user_connected(id))

    {

        set_ent_rendering(id, kRenderFxGlowShell,  iRcolor,  iRcolor,  iRcolor, is_user_alive(id) ? kRenderGlow : kRenderNormal, 25);

    }

}

Glow is present even before i buy the item; i get glow the moment i join the server without having to buy the item.

So, i listed the problems. It seems the first method works best for me - i will use the first method.

Thanks.

Re: How to solve this "undefined symbol" error?

@GlobalPlague. Method 1 is more efficient. Regarding Method 2, same as fm_set_ent_rendering.
