Alice Cecile	557ab9897a	Make get_resource (and friends) infallible (#4047) ... # Objective - In the large majority of cases, users were calling `.unwrap()` immediately after `.get_resource`. - Attempting to add more helpful error messages here resulted in endless manual boilerplate (see #3899 and the linked PRs). ## Solution - Add an infallible variant named `.resource` and so on. - Use these infallible variants over `.get_resource().unwrap()` across the code base. ## Notes I did not provide equivalent methods on `WorldCell`, in favor of removing it entirely in #3939. ## Migration Guide Infallible variants of `.get_resource` have been added that implicitly panic, rather than needing to be unwrapped. Replace `world.get_resource::<Foo>().unwrap()` with `world.resource::<Foo>()`. ## Impact - `.unwrap` search results before: 1084 - `.unwrap` search results after: 942 - internal `unwrap_or_else` calls added: 4 - trivial unwrap calls removed from tests and code: 146 - uses of the new `try_get_resource` API: 11 - percentage of the time the unwrapping API was used internally: 93%	2022-02-27 22:37:18 +00:00
danieleades	d8974e7c3d	small and mostly pointless refactoring (#2934) ... What is says on the tin. This has got more to do with making `clippy` slightly more *quiet* than it does with changing anything that might greatly impact readability or performance. that said, deriving `Default` for a couple of structs is a nice easy win	2022-02-13 22:33:55 +00:00
Jakob Hellermann	b1476015d9	add some more pipelined-rendering shader examples (#3041) ... based on #3031 Adds some examples showing of how to use the new pipelined rendering for custom shaders. - a minimal shader example which doesn't use render assets - the same but using glsl - an example showing how to render instanced data - a shader which uses the seconds since startup to animate some textures Instancing shader:  Animated shader:  (the gif makes it look a bit ugly) Co-authored-by: Carter Anderson <mcanders1@gmail.com>	2022-01-05 19:43:11 +00:00
