Creating Player

Drawing

• Make rough prototypes
• Fix on a design
• Fix light source on a layer to make lights and shadows consitent consistent for all other drawings
• Use layers to separately draw different parts
  • Use layers to add paint to each part
  • Merge outline and painted layer of each part
• Make a new image of all parts by copy pasting the parts from the layers
• Disable background layer for transparent background
• Export as PNG

Importing

• Drag PNG into Unity
• SpriteMode Multiple
• FilterMode Point(NoFilter)
• SpriteEditor
• Draw Boxes to separate parts
• TIP: Use AlphaMode (Right of Apply button) for better view
• Set pivots (points where resizing and rotation are applied)
• Apply

Rigging the Player

• Drag each part into scene view
• Arrange according to original image
• Set OrderInLayer
• Create EmptyObject Player
• Drag all parts as children into Player Object
• Parent each part in hierarchy (Ex: Head as parent to eyes) to use same pivot

Animation

• Window Animation Animation
• Select Player in Hierarchy
• NOTE: DO NOT make changes to Player Object
• AnimationWindow CreateAnimation
• Use RecordMode
• Select a keyframe at 1:00
• Make Changes to parts
• TIP: Use ShiftClick to select multiple keyframes at that time point
• TIP: Use TopMost point to select all keyframes at that time point
• TIP: Use Space while mouse in timeline pane to Pause/Play
• TIP: Select multiple keyframes and drag to increase decrease speed of animation
• TIP: To Make Loop effect select all keyframes in first time point and paste it as a new last time point
• TIP: Properties show the variating keyframes in respective row
• TIP: Add Multiple overlapping subtle changes to make animation more interesting
• Run Animation
  • Move left leg up at 0:00 in timeline
  • At 0:10 move left leg down and right leg up
  • copy paste keyframes from first at end 0:20
  • To Avoid both legs being in the air at same time
    • Copy paste Right leg keyframes from 0:00 to 0:07
    • Copy paste Left leg keyframes from 0:10 to 0:17
    • Which makes one leg grounded before lifting other leg
  • Move the body down at 0:05, Up at 0:10, Down at 0:15

Player Movement

Animation Controller

• Window Animation Animator

• Parameters IsRunning

• TIP: Use Bool Parameters for looping animations. Use Triggers ans HasExitTime for one time animations

• Select Idle AddTransition to Run

• Conditions IsRunning True

• HasExitTime Disable

• TIP: TransitionDuration 0.1. Using 0 makes animation suddenly snap from one to another.

• Repeat for Run to Idle Transition

• Changing IsRunning through code

  if(moveInput != Vector2.zero){
      animator.SetBool("IsRunning", true);
  }else{
      animator.SetBool("IsRunning", false);
  
  }

Weapon

• Draw different parts of weapon on different layers
• TIP: Glow effects can be added in Unity by adding Halo Component to sprite
• NOTE: ParticleSystem Shape Circle Set Rotation to 0 0 0
• TIP: EffectOverLifetime have predefined graphs to use below the graph editor

Enemies

• Create Base Enemy class

• While creating specific enemy class import from Enemy class instead of MonoBehaviour

  public class MeleeEnemy : Enemy{
  
  }

Drawing Tips

• Draw on paper, Scan and use it as background layer
• TIP: Use ClippingMasks to draw only on the layer
