Smooth Character Control

Overview

This script provides smooth movement and jumping mechanics for a 2D Unity game, featuring:

• Variable jump height based on button hold duration.
• Coyote time for more forgiving jumps.
• Smooth acceleration and deceleration for natural movement.
• Automatic character flipping based on movement direction (optional).

Setup

1. Attach SmoothCharacterControl.cs to your character GameObject.
2. Ensure it has a Rigidbody2D and Collider2D.
3. Mark the ground objects with the Floor tag.
4. Configure input mappings in Unity's Input Manager.

Features

Movement

• Uses horizontal damping for smooth acceleration/deceleration.
• Adjustable movement speed via MovementSettings.
• Character flips based on movement direction.

Jumping

• Coyote Time: Allows jumps shortly after leaving the ground.
• Jump Buffering: Press jump slightly before landing to still trigger a jump.
• Variable Height: Releases early = shorter jump.
• Controlled Fall: Increased gravity after peak for a natural descent.

Key Settings

MovementSettings

Parameter	Description	Default
horizontalDamping	Smoothness of movement changes	0.1f
acceleration	Character's max speed	10f

JumpSettings

Parameter	Description	Default
CoyoteTime	Extra jump window after leaving ground	0.15f
MinJumpMultiplier	Jump reduction when releasing early	0.5f
SpeedToFallOnceReachedMaxHeight	Gravity boost after peak jump	2.5f

How It Works

• Movement: Reads horizontal input, applies SmoothDamp for fluid motion.
• Jumping: Handles coyote time, jump buffering, and variable height.

Modifications

• Adjust Jumpforce to tweak jump height.
• Modify MovementSettings.acceleration for speed changes.
• Tune JumpSettings to refine jump feel.

Requirements

• Unity 2020+
