If the current amount of the player's inventory plus the amount in the plant exceeds the maximum, subtract the current amount the player has from the maximum (50 - 30).

This is the amount that fits in the inventory without exceeding the limit.

Simply add it to the inventory and subtract it from the plant.

50 (limit) - 30 (inventory) = 20 free inventory space

50 (plant) - 20 (free inventory space) = 30 left in the plant

30 (inventory) + 20 (collected) = 50 in inventory

{
    PlantData[plantid][plantDrugs] -= transfer;
    Player[playerid][MarijuanaGrams] += transfer;
}
else // Otherwise transfer all of it.

    Player[playerid][MarijuanaGrams] += PlantData[plantid][plantDrugs];
    PlantData[plantid][plantDrugs] = 0;
