Areas 4, 5, and 6 - Checkpoint Respawn System Applied

Summary

Extended the enemy death checkpoint respawn system to work with enemies in Areas 4, 5, and 6.

Updated Enemy Scripts

1. bat.gd

Used by: Bat enemies and Slime enemies (both use bat.gd script) Change: Added checkpoint respawn tracking for non-stomp collisions

func _on_Hurtbox_body_entered(body: Node) -> void:
    if body is CharacterBody2D:
        # Stomp kills bat
        if body.global_position.y < global_position.y - 4:
            queue_free()
            if body.has_method("bounce"):
                body.bounce()
        else:
            # Player hit from side - record checkpoint respawn
            if RespawnManager:
                RespawnManager.set_death_cause("hazard")
                RespawnManager.record_death_position(body.global_position)
            if body.has_method("take_damage"):
                body.take_damage(1)

Behavior:

  • ✅ Stomp from above → Bat dies, player bounces (no player damage)
  • ✅ Hit from side → Player damaged, respawns at checkpoint (energy cell)

2. plant_bullet.gd

Used by: Plant enemy projectiles Change: Added checkpoint respawn tracking when bullet hits player

func _on_body_entered(body: Node) -> void:
    if body is CharacterBody2D:
        # Record checkpoint respawn for plant bullet hit
        if RespawnManager:
            RespawnManager.set_death_cause("hazard")
            RespawnManager.record_death_position(body.global_position)
        if body.has_method("take_damage"):
            body.take_damage(damage)
    queue_free()

Behavior:

  • ✅ Bullet hits player → Player damaged, respawns at checkpoint (energy cell)

Affected Areas

Area 4

  • Enemies: Ghost (no collision), Bat
  • Energy Cells: Orange and Banana checkpoints
  • Behavior: Bat collisions now use checkpoint respawn

Area 5

  • Enemies: Slime (uses bat.gd script), Spinning saw hazards
  • Energy Cells: 7 energy cells
  • Behavior: Slime collisions now use checkpoint respawn

Area 6

  • Enemies: Plant (shoots bullets), Slime, Bluebird, Spinning saw hazards
  • Energy Cells: 8 energy cells
  • Behavior:
    • Plant bullet hits use checkpoint respawn
    • Slime collisions use checkpoint respawn
    • Bluebird already had checkpoint respawn (updated earlier)

Respawn Behavior Summary

Fall Deaths

  • Death cause: "fall"
  • Respawn location: Area start position
  • Does NOT use checkpoint

Enemy/Hazard Deaths

  • Death cause: "hazard"
  • Respawn location: Near energy cell checkpoint
  • Uses checkpoint (fruit-based respawn points)

Enemies with Checkpoint Respawn

✅ Area 1: Radish, Snail, Duck ✅ Area 2: Radish, Snail, Duck, Bluebird ✅ Area 4: Bat ✅ Area 5: Slime (uses bat.gd), Spinning saws ✅ Area 6: Plant (bullets), Slime (uses bat.gd), Bluebird

Testing Checklist

  • Area 4: Die to Bat → Should respawn at orange/banana checkpoint
  • Area 5: Die to Slime → Should respawn at energy cell checkpoint
  • Area 6: Die to Plant bullet → Should respawn at energy cell checkpoint
  • Area 6: Die to Slime → Should respawn at energy cell checkpoint
  • All areas: Fall off map → Should respawn at area start (not checkpoint)
  • All areas: Collect new energy cell → Checkpoint updates to new position

Implementation Complete ✅

All enemy types across Areas 1, 2, 4, 5, and 6 now consistently use the checkpoint respawn system when killing the player through hazard contact.
