Collision Filters

[trommlbomml]

Would be really great, even to improve performance: Define groups and tell the world which groups can collide. for example i would not like to collide projectiles to each others but to collide with tanks.

HC used to have this feature, but with the immediate mode interface it is not necessary anymore. You can define your own group handling, e.g.:

for b in pairs(bullets)
    for other in pairs(HC.neighbors(b))
        if not other.isProjectile and other:collidesWith(b) then -- or if other.group ~= b.group then
            handleCollision(b, other)
        end
    end
end

Note that this is exactly how HC would implement it, so there is no performance gain putting this into the library.

great, thank you!
