Initialize Shader System

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

Purpose: Load and initialize fragment shaders for Shader components.

Components used:

• Shader (contains shaderPath, uniforms_float, isLoaded, shader shared_ptr)

Behavior

• For each Shader not yet loaded and with a valid shaderPath, load an sf::Shader into memory.
• Initialize the texture uniform to sf::Shader::CurrentTexture and apply provided float uniforms.
• On failure, log an error and reset the shader pointer to nullptr.

Main signature

void InitializeShaderSystem(Eng::registry &reg,
    Eng::sparse_array<Com::Shader> &shaders);

Notes

• Shaders are stored as std::shared_ptr<sf::Shader>.
• Idempotent: the system will not reload a shader already marked isLoaded.
