Touch Simulator For Unity

Simulate multi-touch using mouse in Unity Editor. TouchSimulator allows mouse left click and right click to send Vector2 data needed to simulate a pinch input in a smarthphone screen.

Dependencies

This script is using Unity's InputSystem package.

How to Use

1. Import TouchSimulator.cs to your Unity project.

2. Create a Canvas with its RenderMode to Screen Space - Overlay

3. The component Canvas Scaler's UI Scale Mode to Scale With Screen Size

4. Add TouchSimulator to the canvas.

5. As the child of the canvas, create an empty gameObject, and name it "Touch". As the children of Touch, make two empty gameObjects, and name them "Primary" and "Secondary".

    Canvas
    └ Touch
        └ Primary
        └ Secondary
   

   Add Image component to those empty gameObjects, so you can see their position.

6. In TouchSimulator, assign Touch to Touch field, Primary to Pinch Primary, and Secondary to Pinch Secondary.

7. Subscribe to any of TouchSimulator's delegates:

   • OnTapInput
   • OnTapSecondInput
   • OnDeltaInput
   • OnPositionInput
   • OnPinchInput
