Forge - Miscellaneous stuff – player input, rendering, GUI, chat, sounds

Player Input

• KeyBindingRegistry – allows you to add your own keybindings to the vanilla ones – (for example some vanilla keybindings are A for left and D for right).  Your custom keybindings will appear on the options page so that the player can change them.
• MouseEvent – allows you to intercept mouse clicks and mouse movement before the vanilla code sees it.

Rendering

A lot of the custom stuff related to rendering has been covered in the other sections, however there are also quite a few other events related to rendering, listed below:

• Various events used to customise Biome-dependent rendering, such as grass colour – see BiomeEvent.
• FOVUpdateEvent (FOV = Field of View, which means how “wide” your view is)
• RenderGameOverlayEvent gets called for a whole stack of different parts of the screen overlay, such as hotbar, crosshairs, health bar, etc.  See enum ElementType in the event for more information.
• DrawBlockHighlightEvent – draw the highlight box around the block when your cursor is pointing at it
• Another bundle of Events under RenderLivingEvent and RenderPlayerEvent can be used to control the rendering of the player and other entities in quite some detail.

Graphical User Interface

I’m a bit rubbish on this section because I’ve never actually customised a GUI.  From what I can tell, there are a few forge-related additions:

• AchievementPage.registerAchievementPage lets you add your own achievement pages.
• NetworkRegistry.registerGuiHandler (using IGuiHandler) – not sure how to use this.
• GuiIngameForge – replace vanilla in-game overlays with many extra events, and also adds a large number of  flags you can change to turn rendering of HUD elements on/off – for example hotbar, crosshairs, helmet, experience bar, etc.
• GuiControlsScrollPanel – accommodates any extra key bindings you have added to the KeyBindingRegistry
• GuiOpenEvent – used to replace a GUI with your own customised version
• PlayerOpenContainerEvent – when opening a GUI container.

Chat

There are a few interesting events related to chat:

• NetworkRegistry.registerChatListener(using  IChatListener) for intercepting chat messages including commands
• NetworkRegistry.registerConnectionHandler(IConnectionHandler) which gives control over clients and players connecting to the server.
• CommandEvent
• ServerChatEvent
• ClientChatReceivedEvent

Sounds

Sounds are registered using SoundLoadEvent  instead of a registry call.  Don’t ask me why.  They are played using using vanilla methods such as SoundManager.playSound.  Some related events are

• SoundSetupEvent
• PlayBackgroundMusicEvent
• PlaySoundEffectEvent
• PlaySoundEffectSourceEvent
• PlaySoundEvent
• PlaySoundSourceEvent
• PlayStreamingEvent
• PlayStreamingSourceEvent
• PlaySoundAtEntityEvent
