Box2d Filtering Alternatives Libgdx The query filter is used to filter collisions between queries and shapes. for example, you may want a ray cast representing a projectile to hit players and the static environment but not debris. Filtering collisions in box2d is pretty simple. figured i include the code. also, as you can see moving a body is pretty much the same as moving a sprite via.
Java Box2d Filtering Mask Group Category Stack Overflow This document explains how to use box2d's collision filtering system, how it works internally, and provides examples of common use cases. for information about collision detection in general, see collision system. Box2d tutorials so far in every scene we have made, all the shapes were able to collide with all the other shapes. that is the default behaviour, but it's also possible to set up 'collision filters' to provide finer control over which shapes can collide with each other. Sometimes you might want to alter the collision filter of a fixture depending on events in the game. you can change each of the categorybits, maskbits, groupindex by setting a new b2filter in the fixture.

Box2d is a 2d physics engine for games. contribute to erincatto box2d development by creating an account on github. Collisions between fixtures of different group indices are filtered according the category and mask bits. in other words, group filtering has higher precedence than category filtering. Box2d supports 16 collision categories. for each fixture you can specify which category it belongs to. you also specify what other categories this fixture can collide with. Built with sphinx using a theme provided by read the docs. Box2d allows you to avoid destroying bodies by deleting your b2world object, which does all the cleanup work for you. however, you should be mindful to nullify body pointers that you keep in your game engine.
