Initialize Drawable Animated System

Source: client/engine/systems/SystemsFunctions/InitializeAnimationSystem.cpp

Purpose: Initialize Drawable components for entities that have an AnimatedSprite by loading the texture, setting the origin, and configuring the initial frame region.

Components used:

  • AnimatedSprite
  • Drawable
  • Transform

Behavior​

  • Load the texture from drawable.spritePath if not already loaded.
  • Set the sprite origin accounting for animation frame size and the transform.
  • Set the sprite IntRect to the current frame.

Main signature​

void InitializeDrawableAnimatedSystem(Eng::registry &reg,
    Eng::sparse_array<Com::Transform> const &transforms,
    Eng::sparse_array<Com::Drawable> &drawables,
    Eng::sparse_array<Com::AnimatedSprite> const &animated_sprites);

Notes​

  • Logs an error to std::cerr if texture loading fails.
