WebYour C++ structure should be padded accordingly if you want to use it as a convenience for mapping data (this, note, doesn't always scale well). Your issue, then, is that an HLSL boolean is four bytes, but one byte on the CPU side (in your specific implementation).hitzekollaps kleinkind symptomeWebMar 26, 2024 · In C++ bool is just the standard one which has a size of 1. There are several solutions possible. One would be to use BOOL everywhere, forcing C++ to use an int as the C side currently does. Or to use stdbool.h which is compatible with C++ but would not be backwards ABI compatible since this changes the size of bool on the C side. hitzekoller pokemon purpurWebApr 8, 2024 · I claim that the latter is almost always what you want, in production code that needs to be read and modified by more than one person.
