Called for each fixture found in the query. You control how the ray cast proceeds by returning a float: return -1: ignore this fixture and continue return 0: terminate the ray cast return fraction: clip the ray to this point return 1: don't clip the ray and continue
fixture | the fixture hit by the ray |
point | the point of initial intersection |
normal | the normal vector at the point of intersection |
