Character Control Tips And Tricks

Character Slow When Rubbing Against Surfaces

1. If a character is slowed down when running against surfaces then your best bet is to apply a frictionaless material to the character’s collider.

For 2D Friction

1. Inside your project window create a new physics material by right clicking and selecting Create > 2D > Physics Material 2D.

2. Inside the material set bounciness to 0 and Friction to 0

3. Inside your character’s collider, set the physics material to the one you just created.

Orient Characters With The Mouse Position

Here is a quick script that gets you the mouse’s in game position along the x,y plane. It does this by projecting a ray from the camera though the mouse and checks where the ray intersects with the plane. If no intersection occurs it just returns a zero vector.

MouseUtilities.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;

public static class MouseUtilities
{
    // Projects a ray from the camera through the mouse cursor.
    // Gets the position of the raycast that intersects along the x and z plane.
    public static Vector3 GetMousePosition()
    {
        Ray ray = Camera.main.ScreenPointToRay(Mouse.current.position.ReadValue());
        // create a plane at 0,0,0 whose normal points to +Z:
        Plane xyPlane = new Plane(Vector3.forward, Vector3.zero);
        // Plane.Raycast stores the distance from ray.origin to the hit point in this variable:
        float distance = 0;
        // if the ray hits the plane...
        if (xyPlane.Raycast(ray, out distance))
        {
            // get the hit point:
            return ray.GetPoint(distance);
        }
        else
        {
            // Return Zero if no intersection occurs
            return Vector3.zero;
        }
    }
}
