Let's review what was changed: https://github.com/vleue/bevy_workshop/compare/07-level-loading..08-action-zones

Use Fixed Z Indexes

Use fixed values for the z indexes so that the game renders the same every time.

Tips:

• Look for every from_xyz and replace the third value by a different index
• Ground in the back, then flag, then player in the front

Switches

Add a switch zone that enables the flag in the level.

Tips:

• Create a new tile in the level and display it
• Start with the flag disabled
  • Add a bool to the component: Flag(bool)
  • When false, don't trigger winning when reaching the flag
• When getting near the switch, change the Flag component to true
• You can use different sprites to show whether the flag is enabled or not

PowerUps

Add an item to pick up that change how the player jumps.

Tips:

• Create a new tile in the level and display it
• When getting near the powerup, add a new component to the player
• In the system controlling player jumps, query for the optional component
• If the component is present, change how jumping behaves
