I'm trying to make Medic be able to heal sentries and whatnot (mostly sentries) but i can't manage to make the beam attach to like in this screenshot

PHP Code:

new Entity = GetClientAimTarget(client, false);
PrintToChat(client, "AimTarget: %i", Entity);
new Weapon = GetEntPropEnt(client, Prop_Send, "m_hActiveWeapon");
PrintToChat(client, "Weapon: %i", Weapon);
        
if (Entity > 0 && IsValidWeapon(Weapon))
{
    SetEntProp(Weapon, Prop_Send, "m_hHealingTarget", Entity);
    SetEntProp(Weapon, Prop_Send, "m_bHealing", 1);
}
else
{
    CPrintToChat(client, "{red}You must be aiming at something for this to work.");
    return Plugin_Handled;
} 


This just causes the medigun to play the start healing animation but doesnt actually do anything else

Use DHooks or write extension to hook CWeaponMedigun::AllowedToHealTarget(CBaseEnti ty *) which is probatly bool and make it return true.
There's no vtable for this function so you'il need to get signature or ask someone to do it for you.

Edit:

AllowedToHealTarget function has string inside it
"weapon_blocks_healing"
So it probatly will be easy to get windows signature for it

When i have time i might try to get it

Edit 2:

Linux Signature:

PHP Code:

@_ZN14CWeaponMedigun19AllowedToHealTargetEP11CBaseEntity 


Windows Signature:

PHP Code:

\x55\x8B\xEC\x51\x53\x57\x8B\xF9\x8B\x87\xE4\x01\x00\x00

How Do I Use Dhooks ?

PHP Code:

#include <sourcemod>
#include <sdktools>
#include <dhooks>
#pragma semicolon 1

new Handle:hAllowheal;
new Handle:hGameConf;
new Address:HealTarget;

public OnPluginStart()
{
    hGameConf = LoadGameConfigFile("tf2.arthurdead");
    HealTarget = GameConfGetAddress(hGameConf, "CWeaponMedigun");
    hAllowheal = DHookCreate(HealTarget, HookType_Entity, ReturnType_Bool, ThisPointer_CBaseEntity, AllowHealCallback);
}

public MRESReturn:AllowHealCallback(Address:this, Handle:hReturn)
{
    DHookSetReturn(hReturn, true);
    return MRES_ChangedOverride;
}

public OnClientPutInServer(client)
{
    DHookEntity(hAllowheal, false, client);
} 


(14) : warning 213: tag mismatch (hAllowheal = DHookCreate(HealTarget, HookType_Entity, ReturnType_Bool, ThisPointer_CBaseEntity, AllowHealCallback);)

PHP Code:

        "Addresses"
        {
            "CWeaponMedigun"
            {
                "signature" "AllowedToHealTarget"                
            }
        }
        "Signatures"
        {
            "AllowedToHealTarget"
            {
                "library" "server"
                "windows" "\x55\x8B\xEC\x51\x53\x57\x8B\xF9\x8B\x87\xE4\x01\x00\x00"
            }
        }

That's a familiar screenshot

I think AllowedToHealTarget only sets the heal target, though, which can obviously be done manually with ease. We just need to find the actual healing method, if that isn't it...although it might only work on players.

You can literally set m_hHealTarget or whatever it was called to things you wouldn't normally be able to heal.

Well, at least enemy teammates. I don't know about setting it to any arbitrary entity.

Then you could use a timer or something to control healing if m_bHealing doesn't do it already.

Teach us your ways, Master

There will be a flag set which disallows buildings to be healed. Look at the code in IDA to find it.

My guesses is that medi gun can heal only one target at once, but to allow healing each other, you should use DHooks and make something like this.

If i could somehow get the offsets.
Yeah, that would be great

[Dr. Greg House]

I'll look for a solution after dinner.

EDIT:

.text:0071DC40 ; CWeaponMedigun::IsAllowedToTargetBuildings(void)
.text:0071DC40 _ZN14CWeaponMedigun26IsAllowedToTargetBuildingsEv proc near
.text:0071DC40                 push    ebp
.text:0071DC41                 xor     eax, eax
.text:0071DC43                 mov     ebp, esp
.text:0071DC45                 pop     ebp
.text:0071DC46                 retn
.text:0071DC46 _ZN14CWeaponMedigun26IsAllowedToTargetBuildingsEv endp

Detour with an extension and always return yes? Although it seems there is a field for that which you could find.
