Handle multiple controller input layouts?
I've been looking around for an answer about how to handle multiple controller input layouts, and all the answers I've seen suggest making a separate layout for each controller. The answers are also pretty old (a few years) and I'm wondering if there's a better new method of handling this?
Some controllers use Axis for D-pad, others use buttons, so far all I am left with is hard-coding for each controller type, and that is just a pain, as not all controllers have the same button mapping/axis mapping etc.
I can't have a menu to remap controls either (as far as I know) for Android without putting the user through hassle.
Any suggestions would be greatly appreciated :)
The best option I know of is to use a different Input Manager than the default unity manager, such as Input Manager.
You might also consider implementing several managers as instances of a ScriptableObject, which would allow you to change default mappings based on the controller ID.
Here's one way you could implement it (The interface is the same as UnityEngine.Input):
[Serializable]
public class AxesMapping
{
public string axisName;
public string inputManagerAxis;
}
public class CustomInput : ScriptableObject
{
/// <summary>
/// The default custom input is simply a pass-through
/// </summary>
static CustomInput currentCustomInput;
public static CustomInput CurrentCustomInput
{
get
{
currentCustomInput = currentCustomInput
?? ScriptableObject.CreateInstance<CustomInput>();
return currentCustomInput;
}
set
{
currentCustomInput = value;
}
}
#region Inspector Properties
public string[] controllerIDList = { };
public AxesMapping[] axesMappings = { };
#endregion Inspector Properties
/// <summary>
/// Parsing a dictionary of mappings is faster than parsing an array, so this should
/// be used instead of the axesMappings field.
/// </summary>
Dictionary<string, string> mappedAxes;
protected Dictionary<string, string> MappedAxes
{
get
{
mappedAxes = mappedAxes
?? axesMappings.ToDictionary(am => am.axisName, am => am.inputManagerAxis);
return mappedAxes;
}
}
#region "Overridden" UnityEngine.Input methods
//
// Summary:
// ///
// Returns the value of the virtual axis identified by axisName.
// ///
//
// Parameters:
// axisName:
public static float GetAxis(string axisName)
{
string mappedAxis;
if (CurrentCustomInput.MappedAxes.TryGetValue(axisName, out mappedAxis))
{
return Input.GetAxis(mappedAxis);
}
return Input.GetAxis(axisName);
}
//////////////////////////
// Implement all other UnityEngine.Input methods and properties

#endregion "Overridden" UnityEngine.Input methods
}
