UnboundLib

This is a helpful utility for ROUNDS modders aimed at simplifying certain common tasks.

Usage

NetworkingManager

The NetworkingManager abstracts the default Photon networking capabilities away into an easy-to-use interface you can use for communication between clients. Example usage:

private const string MessageEvent = "YourMod_MessageEvent";

NetworkingManager.RegisterEvent(MessageEvent, (data) =>
{
	ModLoader.BuildInfoPopup("Test Event Message: " + (string)data[0]);    // should print "Test Event Message: Hello World!"
});

// send event to other clients only
NetworkingManager.RaiseEventOthers(MessageEvent, "Hello World!");

// send event to other clients AND yourself
NetworkingManager.RaiseEvent(MessageEvent, "Hello World!");

CustomCard Framework

Create a class for your card, extend the CustomCard class, implement its methods, and then in your mod initialization register your card like so:

void Start()
{
    CustomCard.BuildCard<TestCard>();
}

CustomMap Framework

First create a map in unity by using the package and export your scene to a AssetBundle. Then in your mod initialization register your map like so:

void Start()
{
    LevelManager.RegisterLevels(TestAssetBundle);
}

Credits Framework

Registering credits for a mod is as simple as:

void Start()
{
    Unbound.RegisterCredits(string modName, string[] credits, string linkText, string linkURL);
}

GameMode Framework

The GameMode framework provides a modding-friendly API for custom game modes, allowing mods to target them without having to know about their existence.

Custom game modes are defined in two layers: the actual game mode class that does all the heavy gameplay logic, and a handler class that provides an interface between mods and the game mode.

Hooks

The framework offers a flexible hook system. With hooks, mods can trigger actions at specific points of time as a game is running, without needing to know anything about the specific game mode or its implementation.

Triggering hooks

Game modes can trigger async hooks whenever they wish:

private IEnumerator RoundStart()
{
	// Hook keys are case-insensitive
	yield return GameModeManager.TriggerHook("RoundStart");

	// A healthy set of predefined keys is provided to make hooking on to them easier.
	// Predefined keys should be used in favour of custom ones when possible.
	yield return GameModeManager.TriggerHook(GameModeHooks.HookRoundStart);
}

Registering hooks

Mods can register hook listeners wherever they wish:

private void Init()
{
	// Hooks are called with the game mode that triggered the hook, which is always the currently active game mode
	GameModeManager.AddHook(GameModeHooks.HookRoundStart, this.OnRoundStart);
}

private IEnumerator OnRoundStart(IGameModeHandler gm)
{
	// Triggers are IEnumerators so they support yields
	yield return new WaitForSeconds(2f);

	UnityEngine.Debug.Log(gm.Name);

	/* Since triggers are IEnumerators, they must be executed within a coroutine. This means triggers are guaranteed to
	 * be able to disrupt the execution of the current game mode.
	 */
	gm.GameMode.StopAllCoroutines();
}

The existing game modes in ROUNDS, namely Arms Race and Sandbox, have also been patched to trigger hooks.

Settings

The framework also adds a setting system to help mods change common game mode settings easily. Settings provide an easy-to-use method for mods to change gameplay, but they place a lot of responsibility onto game modes to provide sufficient settings.

Using settings in a game mode

private void CheckPoints()
{
	if (p1Points >= (int)GameModeManager.CurrentHandler.Settings["pointsToWinRound"])
	{
		WinRound();
	}
}

Changing settings (in a mod)

private void Init()
{
	GameModeManager.AddHook(GameModeHooks.HookInitEnd, this.OnInitEnd);
}

private IEnumerator OnInitEnd(GameModeHandler gm)
{
	gm.ChangeSetting("pointsToWinRound", 10);
}

See /UnboundLib/GameModes for implementation details and example GameModeHandlers.

Development

Building the project is likely to work without having to change anything. However, if your ROUNDS installation resides in somewhere other than C:\Program Files (x86)\Steam\steamapps\common\ROUNDS, you will need to change the path we have pre-configured for you:

1. Copy UnboundLib/UnboundLib.csproj.user.dist to UnboundLib/UnboundLib.csproj.user
2. Change the ROUNDS installation folder path inside UnboundLib/UnboundLib.csproj.user

You can now open the project solution with Visual Studio, and you're set.
