Hello,
how to check if there is a wall between two players? (game csgo)
Thank you.

Using both clients' positions, you can cast a ray from one to the other, and check for collisions. TR_TraceRayFilter will allow you to do this, but depending on your plans you may want a hull trace. Since you'll be using client positions, you will likely need to filter out clients from the trace, hence the filter callback. Inside the include file you'll find different masks, enums, and other flags.

Thanks for reply, I have currently this

PHP Code:

float traceDir[3];
SubtractVectors(iPos, clientPos, traceDir);

TR_TraceHullFilter(iPos, traceDir, const float mins[3], const float maxs[3], MASK_VISIBLE, TraceFilterClients);
if(TR_DidHit()) 
{
    //...
} 


PHP Code:

public bool TraceFilterClients(entity, contentsMask, any data) 
{    
    if (entity > 0 && entity <= MaxClients) 
    { 
        return true; 
    }
    else 
    { 
        return false; 
    } 
} 


I don't know what are maxs and mins.

[Kolapsicle]

Mins and Maxs are points that form the hull. You can define the points yourself, or get the existing values from the clients.

PHP Code:

float vecMins[3], vecMaxs[3];
GetClientMins(client, vecMins);
GetClientMaxs(client, vecMaxs);

Now I am trying to make something like fake explosion.

PHP Code:

float traceDir[3];
SubtractVectors(clientPos, explosionPos, traceDir);

float vecMins[3], vecMaxs[3];
vecMins[0] = 16.0;
vecMins[1] = 16.0;
vecMins[2] = 16.0;
vecMaxs[0] = 16.0;
vecMaxs[1] = 16.0;
vecMaxs[2] = 16.0;

TR_TraceHull(explosionPos, clientPos, vecMins, vecMaxs, MASK_SOLID);
if(!TR_DidHit())
{
     PrintToChatAll("hit!");
} 


It's never working. Can someone help what to use? I tried TraceRay, but maybe with wrong filters or mask.

[Kolapsicle]

Mins is the minimum size of your hull, and Maxs is the maximum size.



If you don't need a hull, then you should use a Ray.

[Minfas]

I tried Ray function but its not doing anything neither I am behind wall or not.

PHP Code:

TR_TraceRayFilter(clientPos, explosionPos, MASK_SOLID, RayType_EndPoint, TraceRayFilter);
if(!TR_DidHit())
{
    PrintToChat(client, "hit!");
} 


[Kolapsicle]

You aren't passing any data to the filter callback. Your trace is probably just hitting the client at clientPos, and returning a collision. See the last parameter of TR_TraceRayFilter.

[Minfas]

Ok, now its working, but even through walls. :/

PHP Code:

float traceDir[3];
SubtractVectors(explosionPos, clientPos, traceDir);

Handle trace = TR_TraceRayFilterEx(explosionPos, traceDir, MASK_SOLID, RayType_Infinite, TraceFilterClients, client);
if(TR_DidHit(trace))
{
    PrintToChatAll("hit!");
} 


PHP Code:

public bool TraceFilterClients(int entity, int contentsMask, any data) 
{    
    if (entity > 0 && entity <= MaxClients) 
    {
        return true; 
    }
    else 
    { 
        return false; 
    } 
}

Your second parameter should be an angle, but traceDir is a vector. Try first getting the angle from the vector with GetVectorAngles.

Also, since you are now passing a client into your filter, you can simplify the filter callback.

PHP Code:

bool TraceFilterClients(int entity, int contentsMask, any data)
{
    return entity == data; // If the entity we collided with is the same as our data (last parameter), return true (filter it)
}
