Detailed Description

ECS component that defines the thickness of a drawable object.

This component stores a positive float value representing the thickness (in pixels) of lines or shapes (e.g., axes, borders). The value must be strictly positive.

Examples:

• A thickness of 1.0f draws a thin line.
• A thickness of 4.0f produces a bold axis.

Exceptions

std::invalid_argument

if the value is zero or negative.

Usage Examples:

• A thickness of 1.0f draws a thin line.
• A thickness of 4.0f produces a bold axis.
