                     float scale,
                     boolean hovered)

Renders a slot. This displays the (by default) green box based on the gui color as well as the item inside and the amount. To make a slot that has functionality, use ItemContainer to create functioning slots.

Parameters:

game - The game instance

manager - The asset manager

slot - The content of the slot to draw

x - The x coordinate

y - The y coordinate

scale - The scale

hovered - If the slot is currently being hovered or not (ie if it should show the hover info of what is in the slot)

renderItemInGui

void renderItemInGui(IGameInstance game,
                     IAssetManager manager,
                     ItemInstance slot,
                     float x,
                     float y,
                     float scale,
                     int color)

Renders an item and its amount. This is similar to renderSlotInGui(IGameInstance, IAssetManager, ItemInstance, float, float, float, boolean), only that it doesn't render the box below the item.

Parameters:

game - The game instance

manager - The asset manager

slot - The item to draw

x - The x coordinate

y - The y coordinate

scale - The scale

color - The color to filter the item's renderer with

describeItem

void describeItem(IGameInstance game,
                  IAssetManager manager,
                  ItemInstance instance)

Renders an item's hover over information on the mouse cursor position. Additionally, it draws the isItemInfoDebug() text and also fires the TooltipEvent.

Parameters:

game - The game instance

manager - The asset manager

instance - The item whose information to draw
