C++ light on floor

[bpm91]

In global tibia we can observe the light that enters the lower floor of the cave, however how can we do this in a global way?

Does anyone know how to make the light penetrate downstairs? from level 8 to 7 for example

Are you using OTC?

This is a client sided feature with cipsoft official game clients I believe.

This can probably be done from the game.cpp file
This may be the right place to do this

void Game::checkLight()

yes otv8

make light from level 7 penetrate level 8 in holes like caves for example..

Does anyone know how to get light into cave holes or stairs from floor 8 to 7?

Theoretically, you would do as follows:
--------------------------------------------------------------
TFS 1.5
"Tile" Class:

// tile.h
class Tile {
public:
    Tile(bool allowLightToPass = false);
    bool allowsLightToPass() const { return allowLightToPass; }

private:
    bool allowLightToPass;
};

"Tile::Tile" Function:

// tile.cpp
Tile::Tile(uint16_t id) {
    ItemType& it = Item::items[id];
    allowLightToPass = it.allowLightToPass;
}

"Game::PropagateLight" Function:

// game.cpp
void Game::propagateLight(const Position& pos, LightInfo& lightInfo) {
    Tile* tile = map->getTile(pos);
    if (tile && tile->allowsLightToPass()) {
        // Propagate light to the floor below
        Position belowPos = pos;
        belowPos.z += 1;
        Tile* belowTile = map->getTile(belowPos);
        if (belowTile) {
            belowTile->applyLight(lightInfo);
        }
    }
}

--------------------------------------------------------------
OTC V8
"Map::drawLight" Function:

// map.cpp
void Map::drawLight(const LightInfo& lightInfo) {
    for (const auto& tile : tiles) {
        if (tile->allowsLightToPass()) {
            // Draw light on the current floor
            drawTileLight(tile, lightInfo);

            // Draw light on the floor below
            Position belowPos = tile->getPosition();
            belowPos.z += 1;
            Tile* belowTile = getTile(belowPos);
            if (belowTile) {
                drawTileLight(belowTile, lightInfo);
            }
        }
    }
}

void Map::drawTileLight(Tile* tile, const LightInfo& lightInfo) {
    // Custom drawing logic for a tile
    if (!tile) return;

    // Determine the light intensity and color
    int lightLevel = lightInfo.level;
    int lightColor = lightInfo.color;

    // Adjust light based on the position and level
    int x = tile->getPosition().x;
    int y = tile->getPosition().y;
    int z = tile->getPosition().z;

    // Draw the light
    g_drawLight(x, y, z, lightLevel, lightColor);
}

--------------------------------------------------------------
Finally, being able to add the function to various items via simply inputting the key in items.xml:

<!-- items.xml -->
<item id="12345" name="light-permeable tile" allowLightToPass="true" />

--------------------------------------------------------------
Though, I haven't tested it obviously, but it may give you an idea.

Looks like AI hallucination. Code above for sure will not work, as 'programmer' thought that OTCv8 and TFS 1.5 are parts of same code and share C++ variables.
There is nothing to change on server side. All items (from floor above = ground level) and items information from Tibia.dat are already in OTCv8. If it does not render light from level above, it's probably not implemented in client.

ty bro i will try

Any idea ?

I got information from a programmer who works on otcv8, would anyone know what is done to make this happen?

Best to do is to share the solution in the thread to be closed by any mod
