EngineLib Script Integration

I fully replaced the previously hardcoded PlayerMovementSystem with an ObSL script implementation using new EngineLib bindings.

The movement logic is now handled externally through scripting instead of being directly implemented in C++.

New EngineLib Bindings

entity management

Added bindings for basic entity operations:

• CreateEntity Creates a new entity
• Destroy Removes an entity
• HasComponent Checks whether an entity has a specific component
• RemoveComponent Removes a component from an entity

global functions

• get_dt Retrieves delta time
• CloseWindow Closes the glfw window

Input System

Added script access to input handling:

• Input_IsKeyDown Checks if a key is currently held
• Input_IsKeyPressed Checks for a key press event
• Input_IsMousePressed Checks if a mouse button is pressed
• Input_GetMouseWorldPos Gets the mouse position converted to world space

Movement / Hex Grid Functions

Added bindings for interacting with movement components:

• GetSelectedHex Gets the currently hovered hex tile
• SetPathToHex Sets a movement target path for an entity with a MovementComponent

Camera

Added camera manipulation support:

• Camera_GetPosition Gets the camera position
• Camera_SetPosition Sets the camera position
• Camera_Move Moves the camera
• Camera_PanScreenSpace Moves the camera relative to screen space
• Camera_GetZoom Gets the current camera zoom

Hex Rendering

Added bindings for controlling grid visuals:

• ClearSelectionOverlay Clears the hex selection overlay
• ClearPathTarget Clears the path target visual marker

ClearPathTarget is currently named poorly. It only clears the grid overlay visualization, not the actual movement target!!!

---

summary

• Removed the old hardcoded PlayerMovementSystem
• Migrated player movement logic into script format
• Added engine bindings required for script-driven gameplay
• Camera movement, input handling, and hex selection now work through scripts
• Even more gameplay code can now be modified without recompiling the engine :)
