check(expression);

This macro executes the expression and, if it results in a false assertion, halts execution. The expression is only executed if the macro is compiled into the build (DO_CHECK=1). This is the simplest form of the check() macros.

Examples:

Code: Select all

check(Mesh != nullptr);
check(bWasInitialized && "Did you forget to call Init()?");

Extremely useful. Also has a checkf() version that behaves like printf().
