[ad_1]
I’m following the “Touch Samples” sample project that comes with the “input system” package.
In one of the sample scene, there is a script that defines a custom composite Binding (for example the 2D vector composite).
I’m practically rewriting the same scripts except changing some inputs to be added to the composite, but it’s throwing me these errors, and since I’m relatively new to writing code don’t know how to begin solving the issue. The manual and the scripting API are no help either.
these are the errors
this is the example Script that adds a custom composite.
using UnityEngine;
using UnityEngine.InputSystem;
using UnityEngine.InputSystem.Layouts;
using UnityEngine.InputSystem.Utilities;
#if UNITY_EDITOR

namespace InputSamples.Drawing
{
/// <summary>
/// Simple object to contain information for drag inputs.
/// </summary>
public struct PointerInput
{
public bool Contact;
/// <summary>
/// ID of input type.
/// </summary>
public int InputId;
/// <summary>
/// Position of draw input.

}
// What we do in PointerInputManager is to simply create a separate action for each input we need for PointerInput.
// This here shows a possible alternative that sources all inputs as a single value using a composite. Has pros
// and cons. Biggest pro is that all the controls actuate together and deliver one input value.
//
// NOTE: In PointerControls, we are binding mouse and pen separately from touch. If we didn't care about multitouch,
// we wouldn't have to to that but could rather just bind `<Pointer>/position` etc. However, to source each touch
// as its own separate PointerInput source, we need to have multiple PointerInputComposites.
