Hello, any way to detect when an HE grenade is touching a wall/ground?

thanks

[mjmfighter]

Yes there is a way to detect when it touches a wall or ground or even a person. With SDKHooks its something like this:

PHP Code:

#include <sdkhooks>

public OnEntityCreated(iEntity, const String:classname[]) 
{
    new iGrenade = iEntity;
    if(StrEqual(classname, "hegrenade_projectile")) 
    {    
        SDKHook(iGrenade, SDKHook_StartTouch, GrenadeTouch);
    }
}

public GrenadeTouch(iGrenade, iEntity) 
{
    //code here when nade touches someone or something.  if it touches someone iEntity will be > 0 (client index)
}

Thanks you dude!!!

And any way to force this he to explode :>?

Try

PHP Code:

SetEntPropFloat(iGrenade, Prop_Data, "m_flDetonateTime", GetGameTime()); 


[BoBzY]

Nop, it doesnt work

[Peace-Maker]

Try this. It's linux only though. If it does work, post back and we put some nicer gamedata file together

PHP Code:

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

// SDKCall
new Handle:g_hDetonate;

public OnPluginStart()
{
    // Prepare Detonate call
    StartPrepSDKCall(SDKCall_Entity);
    if(!PrepSDKCall_SetSignature(SDKLibrary_Server, "@_ZN20CHEGrenadeProjectile8DetonateEv", 0))
        SetFailState("Can't find CHEGrenadeProjectile::Detonate(void) symbol");
    g_hDetonate = EndPrepSDKCall();
}

public OnEntityCreated(iEntity, const String:classname[]) 
{
    if(StrEqual(classname, "hegrenade_projectile")) 
    {    
        SDKHook(iEntity, SDKHook_StartTouch, GrenadeTouch);
    }
}

public GrenadeTouch(iGrenade, iEntity) 
{
    SDKCall(g_hDetonate, iGrenade);
} 


This will hopefully get the HE to detonate on first touch with anything, not only walls though. You need some more checks on iEntity if you need to have it to detonate on walls. like if(iEntity == 0).. would detonate on the floor either.

It work perfectly, good job :-)

But I have a new question

It is possible for the projectile to have a longest life?

[Peace-Maker]

Longest life? Like after 3 seconds without touching anything they explode anyway?
You could create a timer while hooking StartTouch and do the SDKCall in the callback. Make sure to pass entity index as reference (EntIndexToEntRef/EntRefToEntIndex)

[BoBzY]

Like after 3 secs WITHOUT touching something, they dont explode
So, I can throw HE, if he dont touch anything in 7 secs, she still 'flying'
gtg sleep, if you know how to do, Ill try tomorrow

I rly appreciate your help, thanks for your time dude ;)

peace & gn8

Don't know it is possible to block detonation with sourcepawn. I don't know of any way. You'd need to detour the Detonate method in an extension..

Still here's the better variant using a gamedata file. Added the windows signature either. YAY - FIRST SIGNATURE SEARCH FOR ME
