A object defined within the Source Engine as having characteristics which differentiate it from "the world" (world brushes).
There are three main types of entities:
- Brush entities are built from brushes and covers its area of effect. They include things such as triggers, conveyor belts, and rain.
- Point Entities are created at a position point in the grid, and has no area of effect of its own, unless it is given a model.
- Nodes are created like point entities, and will together create a network that will aid the NPCs (See below.) to gain knowledge about their surroundings, making them smarter than their basic programming.
There are several sub-types of point entities:
- Logic entities are invisible entities that affect the game, including AI managers, lights, and choreography.
- Prop entities are non-living objects that uses a model for its appearance and function. They can be static-, dynamic- or physics-based.
- NPCs stands for "Non-Playing Characters", and refers to all the living/robotic opponents and allies beside the player(s). They have predefined models and behavior AI of their own. Todo: Vehicle drivers might be a possible exception that won't have a model. Please verify this.
