In some maps, where many many allies in a small area - playing as a soldier is enraging, because when you shooting with rockets through allies, it's simply exploding and making damage to you.

How to make rockets do not exploding by allies, just fly through them?

[backwards]

I belive you would have to hook SDKHook_ShouldCollide on the entity of the rocket projectile on the spawn event. Then on when the function is called you will have to check the other entity it's colliding with, if it's a player and it has the same teamindex as the m_hOwner netprop, then you would have to return false and plugin_changed possibly. This should prevent it from colliding with teammates, however there might be something easier like a CVAR that exists for this that i'm unaware of as i don't play tf2.

That's interesting hook, but it doesn't gives enough information about with which exactly entity we colliding.

PHP Code:

//entity - hooked entity
//collisiongroup - with that type of entity we colliding(for ex COLLISION_GROUP_PLAYER)
//contentmask - collide mask of hooked entity? Or colliding entity?
//originalresult - collision result by default collision rules
public bool:ShouldCollide( entity, collisiongroup, contentsmask, bool:originalResult)
{
    // modify collision rules return false for not collide, true - for collide
} 


We can't get colliding player team because don't know it Entity index.
And I tested this hook and it doesn't work in ~50%, it's just exploding with allies without calling collide func, but sometimes calling...

Haven't tried it myself, but try DHooks and hook CBaseProjectile::CanCollideWithTeammates()

[oplkill]

Any tries about DHooks CBaseProjectile::CanCollideWithTeammates() even CBaseProjectile::GetCollideWithTeammatesDelay () are crashing the server without any logs...

I used that code:

PHP Code:


new Handle:hTeammateCollide;

public OnPluginStart()
{
    new Handle:temp = LoadGameConfigFile("dhooks-test.games");
    
    if(temp == INVALID_HANDLE)
    {
        SetFailState("Why you no has gamedata?");
    }
    
    new offset;

    offset = GameConfGetOffset(temp, "CanCollideWithTeammates");
    hTeammateCollide = DHookCreate(offset, HookType_Entity, ReturnType_Bool, ThisPointer_CBaseEntity, CanCollideWithTeammates);
    CloseHandle(temp);
}

public OnEntityCreated(entity, const String:classname[])
{
    if (StrContains(classname, "_projectile") > 0)
    {
        PrintToChatAll("created entity = %d", entity);
        DHookEntity(hTeammateCollide, true, entity); //tryed true/false
         }
}

//bool CBaseProjectile::CanCollideWithTeammates()
public MRESReturn:CanCollideWithTeammates(pThis, Handle:hReturn)
{
    DHookSetReturn(hReturn, false);
        return MRES_ChangedHandled; //tryed MRES_ChangedHandled, MRES_ChangedOverride, MRES_Override, MRES_Supercede
}
