Hello.

My code looks like that:

PHP Code:

public bool IsClientColideWithWall(int client){
    float pos[3];
    GetClientEyePosition(client, pos);

    float angles[3];
    float endPos[3];
    float distance;

    Handle trace;

    bool nearWall = false;

    for(int angle = 0; angle < 360; angle+= 30){
        angles[0] = 0.0;
        angles[1] = float(angle);
        angles[2] = 0.0;

        trace = TR_TraceRayFilterEx(pos, angles, MASK_SOLID, RayType_Infinite, TraceFilter, client);

        if(TR_DidHit(trace)){
            TR_GetEndPosition(endPos, trace);

            distance = GetVectorDistance(endPos, pos, true);

            if(distance < 5)
                nearWall = true;
        }

        CloseHandle(trace);
    }
    return nearWall;
}

public bool TraceFilter(int entity, int mask, any data) {
    if(entity == data)
        return false;
    return true;
} 


This code everytime returns FALSE, but when i deleted TraceFilter function and changed tray function for TR_TraceRayEx code starts returning TRUE

Tracehull should be what you want. It uses the player's physical body as the ray. From there add a single unit along the current angle to test if it collides.

Don't forget that this will affect inclines, which means you need to account for stepsize. Which I don't know how to do

I changed my code to:

PHP Code:

public bool IsClientColideWithWall(int client){
    float pos[3];
    GetClientAbsOrigin(client, pos);

    float angles[3];
    GetClientAbsAngles(client, angles)

    float min[3] = { 0.1, 0.1, 0.1 };
    float max[3] = { 10.0, 10.0, 10.0 };

    Handle trace = TR_TraceHullFilterEx(pos, angles, min, max, MASK_SOLID, TraceFilter, client);

    if(TR_DidHit(trace)){
        float endPos[3];
        TR_GetEndPosition(endPos, trace);
        
        float distance = GetVectorDistance(pos, endPos);

        PrintToChat(client, "[%0.1f]", distance);

        if(distance <= 1){
            CloseHandle(trace);
            return true;
        }
        
        CloseHandle(trace);
        return false;
    }

    CloseHandle(trace);
    return false;
} 


and now when i go to the left wall i got low values like 16.0 but when i go to right wall i got high values like 400.00

There's a native for getting a client's mins and maxs. Fix it for a start.

Ok, i changed my code for:

PHP Code:

public bool IsClientColideWithWall(int client){
    float pos[3];
    GetClientAbsOrigin(client, pos);
    pos[2] += 50;

    float min[3];
    GetClientMins(client, min);

    float max[3];
    GetClientMaxs(client, max);

    Handle trace = TR_TraceHullFilterEx(pos, pos, min, max, MASK_SOLID, TraceFilter, client);

    if(TR_DidHit(trace)){
        float endPos[3];
        TR_GetEndPosition(endPos, trace);
        
        HullTest(endPos);

        return true;
    }

    CloseHandle(trace);
    return false;
} 


HullTest func is just a test function which spawn chicken at hull hit position.
Now that function works but not for all walls.

Your code checks if the player would be stuck if you teleported him upwards 50 units. The part of the angles in your previous code is likely necessary, although 5 degrees jump would be better to ensure full accuracy.

Thank you!!

PHP Code:

public bool IsClientColideWithWall(int client){
    float pos[3];
    GetClientAbsOrigin(client, pos);
    pos[2] += 50;

    float min[3];
    GetClientMins(client, min);

    float max[3];
    GetClientMaxs(client, max);

    min[0] -= 5;
    min[1] -= 5;

    max[0] += 5;
    max[1] += 5;

    Handle trace = TR_TraceHullFilterEx(pos, pos, min, max, MASK_SOLID, TraceFilter, client);

    if(TR_DidHit(trace))
        return true;
    
    CloseHandle(trace);
    return false;
} 


PHP Code:

public bool TraceFilter(int entity, int mask, any data){
    if(entity == data)
        return false;
    return true;
} 


That code works very well. You are my life saver.

Wait, this will return true if there is a wall above your head without exact collision. You should manipulate mins / maxs of height to deal with stepsize ( which defaults to 18, not 50 if I remember right ) instead of current position.

I am just unsure how mins works exactly. Also there should be a netprop for stepsize, as there is a cvar ( hidden ) for changing step size.
