Enemies

System Summary

Different types of enemies

There are four different types of enemies that are children of the BaseEnemyClass, EnemyPatrol, EnemyFly, EnemyStationary and EnemyShooting. These four enemies pose threat to the player and should be avoided or stomped on during gameplay. Additionally the MovingPlatform is also a child of this class, although it doesn't pose any threat to the player.

Feature List / Breakdown of Features

Base Enemy:

• When landed on, the player defeats them and gets a bounce, larger if they're holding jump.
• When run into from another direction, the player takes damage.
• All enemy types have properties that can be adjusted.
• Enemies can have tile interactions toggled typically.

Patrolling Enemy:

• Property Ground Speed: Controls how fast the enemy moves on the ground.
• Property Restricted: Controls if the enemy turns or falls when it would pass over an empty tile.
• Property Facing: Controls which direction the enemy is initially facing.

Shooting Enemy:

• Property Direction: Controls the direction that the enemy is shooting.
• Property Random Direction: Disables direction and makes the enemy fire randomly instead.
• Property Fire Rate: Controls how fast the enemy fires.
• Property Shot Speed: Controls the speed of the projectiles the enemy fires.
• Projectile Bounce: Toggle for allowing the player to jump on projectiles.
• Gravity: Toggle for giving the shooting enemy gravity and allowing for vertical tile interaction.

Flying Enemy:

• Property Flying Speed: Controls the speed the enemy is flying at.
• Property Endpoint: Sets the second point the enemy will fly to and from.

Stationary Enemy:

• Property Gravity: Controls if the enemy has gravity applied or if it hovers, also enabled vertical tile collisions.
• Property Facing: Controls which way the enemy is facing.

Important Variables

PropertyFile: Resource = The property file that the enemy is drawing it's properties from..

animatedSprites : AnimatedSprite2D = The animated sprite component of the enemy for transitioning between animations.

Important Functions

• func assign_script(id: String, position: Vector2i) -> void: Assigns the script of the given ID (located in the Resources/Enemies folder) to an enemy at the given position.

• func apply_script(file: Resource) -> void: Applies the effects of the given properties in the file to the enemy, this function is used by finding the enemy at the location specified in the script.

• func apply_gravity(delta: float) -> void: Applies the gravitational forces to the enemies.

• func check_out_of_bounds() -> bool: Checks if the enemy is outside of the bounds of the level.

• func detect_tiles(horizontal: bool = false) -> void: Checks tile collisions under and above, if horizontal is true then it also checks for horizontal collisions. Can collide with bounce and slow tiles.

Future Work / Risks

Future Work:

1. Rename class, Enemy doesn't work since MovingPlatform is also a child of it (and that isn't an enemy)
2. More enemies?

Risks:

• None
