I am trying to get the angle between the weapon and the player to know if their a wall between them.

Here my screenshot modified by vang gog again!



I will use traceray to detect if their a wall between the 2 entity.

[Dr. Greg House]

posEntity2-posEntity1 will give you the vector from entity1 to entity2, which is also the direction from entity1 to entity2. Also the absolute of the vector will be the distance between the two entities.

[Mathias.]

Here my code so far, I am not sure for the angle and I do not know what sort of filter I should put to detect a wall. Thank you for your help, it keep going foward!

PHP Code:

#include <sourcemod>
#include <sdktools>
#include <sdkhooks>

public OnClientPutInServer(client)
{
    SDKHook(client, SDKHook_WeaponEquipPost, OnWeaponEquip);
}
    
public Action:OnWeaponEquip(client, weapon)
{
    decl Float:clientOrigin[3], Float:clientOrigin[3], Float:tracePos[3],;
    GetEntPropVector(client, Prop_Send, "m_vecOrigin", clientOrigin);
    GetEntPropVector(weapon, Prop_Send, "m_vecOrigin", weaponOrigin);
    
    tracePos = origin-weaponOrigin;
    new Handle:trace = TR_TraceRayFilterEx(tracePos, angles, MASK_SOLID, RayType_Infinite, ????);

    if(TR_DidHit(trace))
}

I'm not that familiar with traces, but I'd think you'd want this instead:

PHP Code:

public Action:OnWeaponEquip(client, weapon)
{
    decl Float:clientOrigin[3];
    decl Float:weaponOrigin[3];

    GetClientEyePosition(client, clientOrigin); // Avoid hitting itself
    GetEntPropVector(weapon, Prop_Send, "m_vecOrigin", weaponOrigin);

    new Handle:trace = TR_TraceRay(clientOrigin, weaponOrigin, MASK_PLAYERSOLID, RayType_EndPoint);

    if (TR_DidHit(trace))
    {
        // Hit something
    }
} 


Note that I'm not using an angle at all, but rather tracing the position between the player's eye origin and the weapon origin. Now, it may still hit the player itself or the weapon, which is likely why you needed the filter to begin with... let me try writing that really quickly.

Edit: Here's something that should filter out the player and weapon:

PHP Code:

#include <sourcemod>
#include <sdktools>
#include <sdkhooks>

public Plugin:myinfo = 
{
    name = "New Plugin",
    author = "Unknown",
    description = "<- Description ->",
    version = "1.0",
    url = "<- URL ->"
}

public OnPluginStart()
{
    // Add your own code here...
}

public OnClientPutInServer(client)
{
    SDKHook(client, SDKHook_WeaponEquipPost, OnWeaponEquip);
}

public Action:OnWeaponEquip(client, weapon)
{
    decl Float:clientOrigin[3];
    decl Float:weaponOrigin[3];
    
    new Handle:data = CreateDataPack();
    
    GetClientAbsOrigin(client, clientOrigin);
    GetEntPropVector(weapon, Prop_Send, "m_vecOrigin", weaponOrigin);
    
    WritePackCell(data, client);
    WritePackCell(data, weapon);

    new Handle:trace = TR_TraceRayFilterEx(clientOrigin, weaponOrigin, MASK_PLAYERSOLID, RayType_EndPoint, DontHitMeOrWep, data);

    if (TR_DidHit(trace))
    {
        // Hit something
    }
}

public bool:DontHitMeOrWep(entity, contentsMask, any:data)
{
    ResetPack(data);

    new client = ReadPackCell(data);
    new weapon = ReadPackCell(data);

    if (entity == client || entity == weapon)
    {
        return false;
    }
    
    return true;
} 


btw, didn't the player already pick this weapon up? How could there be anything between them?

It post, so it before the weapon being taked, if I return Plugin_Handled; It should not take the weapon and prevent the players take the weapon through walls. Thank alot this help me. I will try this and give u news.

Post is after the weapon is taken. Try it in an SDKHook_WeaponEquip hook instead. I'm not sure which return value will block the weapon pickup, though... Plugin_Stop?

[Mathias.]

Okay I have tryed it, it look to work but I don't know why he told me everytime something collide when it did not. Here my code and the output.

output:

PHP Code:

filter
entity: 1, client: 1, weapon: 58
hit something, wont pickup the weapon 


code:

PHP Code:

#include <sourcemod>
#include <sdktools>
#include <sdkhooks>

public Plugin:myinfo = 
{
    name = "New Plugin",
    author = "Unknown",
    description = "<- Description ->",
    version = "1.0",
    url = "<- URL ->"
}

public OnPluginStart()
{
    // Add your own code here...
}

public OnClientPutInServer(client)
{
    SDKHook(client, SDKHook_WeaponEquipPost, OnWeaponEquip);
}

public Action:OnWeaponEquip(client, weapon)
{
    decl Float:clientOrigin[3];
    decl Float:weaponOrigin[3];
    
    new Handle:data = CreateDataPack();
    
    GetClientAbsOrigin(client, clientOrigin);
    GetEntPropVector(weapon, Prop_Send, "m_vecOrigin", weaponOrigin);
    
    WritePackCell(data, client);
    WritePackCell(data, weapon);

    new Handle:trace = TR_TraceRayFilterEx(clientOrigin, weaponOrigin, MASK_SOLID, RayType_EndPoint, DontHitMeOrWep, data);

    if (TR_DidHit(trace))
    {
        PrintToChat(client, "hit something, wont pickup the weapon");
    }
}

public bool:DontHitMeOrWep(entity, contentsMask, any:data)
{
    ResetPack(data);
    new client = ReadPackCell(data);
    new weapon = ReadPackCell(data);
    PrintToChatAll("filter");
    PrintToChatAll("entity: %d, client: %d, weapon: %d", entity, client, weapon);
    
    if (entity != client)
    {
        return true;
    }
    
    return false;
}

Thank you, maybe it the my problem then!

[Mathias.]

Everything working now, thank you alot, the problem was the Post (after picked up).

But I have an other problem: I return Plugin_Stop; it prevent the player from picking up the weapon, but the weapon disapear and/or become invisible because when I go back on the weapon location it pick it up (if their no collision between the weapon and the player of course).

Here my code:

PHP Code:

#include <sourcemod>
#include <sdktools>
#include <sdkhooks>

public OnClientPutInServer(client)
{
    SDKHook(client, SDKHook_WeaponEquip, OnWeaponEquip);
}

public Action:OnWeaponEquip(client, weapon)
{
    decl Float:clientOrigin[3];
    decl Float:weaponOrigin[3];
    
    new Handle:data = CreateDataPack();
    
    GetClientAbsOrigin(client, clientOrigin);
    GetEntPropVector(weapon, Prop_Send, "m_vecOrigin", weaponOrigin);
    
    WritePackCell(data, client);
    WritePackCell(data, weapon);

    new Handle:trace = TR_TraceRayFilterEx(clientOrigin, weaponOrigin, MASK_SOLID, RayType_EndPoint, DontHitMeOrWep, data);

    if (TR_DidHit(trace))
    {
        return Plugin_Stop;
    }
    return Plugin_Continue;
}

public bool:DontHitMeOrWep(entity, contentsMask, any:data)
{
    ResetPack(data);
    new client = ReadPackCell(data);
    //new weapon = ReadPackCell(data);
    
    if (entity != client)
    {
        return true;
    }
    
    return false;
} 


[Mitchell]

are you going to release this as a plugin? this might be cool if a server owner wants to stop pickup through walls.

[Mathias.]

Yea I intended to do. It is from category fix but some people might still like to pickup guns throw walls.
Also I intend to put a weapon anti drop throw walls, which teleport the weapon backward with out change the push direction so it will hit the wall in the front and drop on the floor instead of crossing threw it.

And of course a classic one, anti-illegal defuse. This will be fun to do and I will be realy happy to share this plugin to everyone.

Thank you, sorry for my bad english,
