It's currently done pretty straight forward without any inheritance as MapBlock is just used everywhere, maybe in a future we'll have ServerMapBlock over MapBlock. Currently for a simple function let's just use proper objects and add a comment warning * refactoring(Server): fix duplicated function for add/remove node * refactoring(guiFormSpecMenu): add removeAll function to prevent duplicated code * refactoring(ShadowRenderer) + perf: code quality + increase performance * All callers are already using the point and we should never test a function with nullptr node, it's a bug. Removed workaround which was hacky and fix the bug * Drop clientmap lookup from shadowrendered, just use directly its pointer and forbid to push it in the generic list * Reduce memory pressure on the renderShadowObject by preventing deallocating and reallocating multiple vectors on each node * refactoring(MapBlock): reduce exposure of MapBlock::m_static_objects It's not complete as some parts of the code are pretty nested, but it's better than before :) * fix: better working on new functions & drop unwanted 2 lines Co-authored-by: Jude Melton-Houghton <jwmhjwmh@gmail.com> Co-authored-by: Jude Melton-Houghton <jwmhjwmh@gmail.com>
