Notes

Ep 10

• When the missile doesn't match the coord system, create a GO as parent, check the scale, rotate the missile until it matches the parent.

• Physics.OverlapSphere() returns and a array with all GO touching the sphere.

• Use gizmos for the range OnDrawGizmosSelected() and Gizmos.DrawWireSphere()

• With particle system:

  • Set loop on while you are tweaking it.
  • Drag material to the particle system
  • You can set a child (flame), but work on each separately
  • Interesting:

    • General

      • Start Size m/M
      • Start Speed m/m
      • gravity Modifier
      • Start Life m/M

    • Shape

      • Radius

    • Emission

      • Bursts Min

    • Renderer

      • Disable cast shadows and receive shadows

• Light

  • Add Point Light
    • Adjust color
    • Intensity
  • Add Animation window
  • Add new Animation: it creates animation and controller
  • Remember press record in animation panel
  • Change frames then the properties

Ep 11

• [System.Serializable] allows Unity to parse the structure and displays it on the parameter config
• [Header("Optional")] lets the user to know that it's and optional parameter
• Property CanBuild acts like a computed prop
• Quaternion.identity
• In PlayerStats static properties can be modified (Money)
• Nodes can hold a turret from the beginning, setting it in parameters

Ep 12

• Import fonts: in font inspector properties: Create TMP Font asset, generate and save
• Canvas -> canvas -> Render Mode: World Space
• Text -> stretch (hold alt and click)
• Math.Clamp() and string.Format()
• For Text Mesh Pro:
  • using UnityEngine.UI;
  • using TMPro;
  • TextMeshProUGUI type
• Build Effect:
  • Reduce size with time
  • Shape hemisphere
  • Check burst

Ep13

• EnemyDeathEffect - take into account:
  • renderer: drop material
  • size over time
  • emission: rate over time = 1

Ep14

• Import Laser Beamer:
  • Import new asset in the created folder
  • scale = 0.5 and apply
  • In materials:
    • location: Use External Materials (Legacy) and apply, they will show up in the Materials folder
• When importing the texture:
  • Texture Type: Sprite 2D and UI
  • Sprite Mode: single nad apply
• Line Renderer Component added to the LaserBeamer
  • Drop a Material
  • change the positions

Ep15

• Laser Impact

  • Use shape = cone to
  • material: activate Emission, global ilumination: off
  • For better performance, In collision:
    • create a new layer called environment, assign it to nodes and ground
    • collide with: environment (only)
  • Set the direction towards the firePoint

• You can nest particle systems

• LaserGlow

  • Color over lifetime: fade out
  • material: render = additive (legacy)
    • texture: default-particle

Ep16

• Let's move the movement mechanism to its own script
• Use [RequireComponent(typeof(Enemy))] when you want a strict dependency
• [HideInInspector]
• To ensure that EnemyMovement will be run after Enemy (a common practice for debuff)
  • Go to Project Settings -> Script Execution order
  • Add EnemyMovement 100ms after

Ep17

• Game Object (stretched) -> panel -> text:
  • Create TMP font
• Shadow in text not working
• OverlayCanvas -> Canvas scaler:
  • UI Scale Mode: Scale with screen size
  • Screen Match mode and move all to height (disabled because turrets look stretched)
• Static variables carry on from one scene to another
• Use a temporary end game key
• Scene Management:
  • Go to File > Build Settings
  • Drop the MainScene and notice the index
• Tune the highlight of the buttons
• Animation:
  • Background:
    • Add Canvas Group Component (change the alpha without messing around with the color)
  • Game Over text: come down and fade in
    • Add Canvas group
  • Round survived: scale and fade in
    • Add Canvas Group
  • Buttons: pop up
    • Add Canvas Group
    • tweak size and alpha
• Problem with standard turret, no line renderer assigned.

Ep18

• Canvas
  • In the nodeUI, GameObject must be placed where the turret is and the canvas can be repositioned
  • Render Mode: World Space
  • In Text boxes we can use html tags
  • In the inspector, selecting Debug we can see the private variables

Ep 19

- In any canvas, Graphic Raycaster overlaps with the pointing events.

Ep 20

• I messed up with the sellEffect, and I had to undo changes in the file from git history.

Ep 21

• The best way to pause is Time.timeScale = 0f;
• Animator:
  • Update Mode: Unscaled time (to prevent freezing when delta time is 0)
  • For buttons we can create an animator controller (with all states)

Ep 22

• To place the camera in the view: Camera selected and Crtl + Shift + F
• Break prefab instance in modern Unity: Prefab > Unpack completely
• To assign the existing button animation: Add Animator component and for controller select Button
• Add the new scene to Build settings (first slot)

Ep 23

• In an image, when we use a sprite we can control the fill with fillAmount, we need a tiny white sprite.
• White sprites can work with any color (color * 1 = color)

Ep 24

• In order to control the fade animation AnimationCurve lets you use a curve in the inspector.
