Variable Wind

A small script by me put in a lib. Probably interesting for BnG, Forts and Tower with the RubberWorm windy option.

The wind is changed while the worm is moving. If the worm is on the left of the map, the wind goes right, if the worm is on the right, it goes left. If the worm is in the center, there's no wind.
I put in a multiplicator to let you easily change that effect in the script. By default the maximum wind strength possible inside the map bounds is the default WA wind maximum.

Code:

require utils;

float _windStrength;
float _multiplicator;
                
void VariableWind::Init()
{
    _windStrength = 0.0;
    // Increase the multiplicator to have stronger wind
    _multiplicator = 0.65;
}

override void CTurnGame::Message(CObject* sender, EMType type, int size, CMessageData* data)
{
    // Calculations each frame
    if (type == M_FRAME)
    {
        CWorm *worm = GetCurrentWorm();
        if (worm != NullObj)
        {
            // Calculate wind strength
            _windStrength = (worm->PosX - GS->LevelSX / 2) / GS->LevelSX * -_multiplicator;
            Env->Wind = _windStrength;
            CMessageData* messageData = new CMessageData;
            messageData->fparams[0] = _windStrength;
            Root->Message(Root, M_UPDATEWIND, 4, messageData);    
        }
    }
    super;
}

and make variable wind during turn ?

interesting script... :)
btw, does this modification better in performance? i mean remembering current worm PosX and avoiding superfluous calculations?

Code:

require utils;

float _windStrength;
float _multiplicator;
int posXLastFrame;
                
void wind::Init()
{
    _windStrength = 0.0;
    // Increase the multiplicator to have stronger wind    
    _multiplicator = 0.65;
}

override void CWorm::Message(CObject* sender, EMType type, int size, CMessageData* data)
{
    super;
    if (this != GetCurrentWorm()) return;
    // Calculations each frame
    if (type == M_FRAME && posXLastFrame != PosX && Root->IsTimerActive()) 
    {
        // Calculate wind strength
        _windStrength = (PosX - GS->LevelSX / 2) / GS->LevelSX * -_multiplicator;
        Env->Wind = _windStrength;
        CMessageData* messageData = new CMessageData;
        messageData->fparams[0] = _windStrength;
        Root->Message(Root, M_UPDATEWIND, 4, messageData);
        // Remember worm's horizontal position
        posXLastFrame = PosX;    
    }
}

also Root->IsTimerActive() check is also useful i think. there is no need to reset wind if false.
