Sensor:set_categories

Sets which physics categories describe this sensor.

Categories are used to determine which colliders and sensors are allowed to interact with each other. The list of valid categories in your project must be defined using crystal.configure.

Usage

sensor:set_categories(...)

Arguments

Name	Type	Description
...	string	Physics categories describing this sensor.

Examples

local ecs = crystal.ECS:new();
ecs:add_system(crystal.PhysicsSystem);

local pressure_plate = ecs:spawn(crystal.Entity);
pressure_plate:add_component(crystal.Body);
pressure_plate:add_component(crystal.Sensor, love.physics.newCircleShape(4));
pressure_plate:set_categories("triggers");
pressure_plate:enable_activation_by("characters");
pressure_plate:disable_activation_by("monsters", "npc");
