In this episode we:
- use jump sprites instead of the standing/walking sprites
- clean up our sprite map initialization code
- implement vertical facing (looking up and down)
Note: Iterating over ENUMs (starting around 15:59).
My implementation works in clang++, but not g++, since calling motion_type++ is not valid C++.
Instead, you can use loops of the form:
for (int int_value = ENUM_FIRST; int_value < ENUM_LAST; ++int_value) {
Enum value = static_cast<Enum>(int_value);
}
The key is that you are incrementing an integer, and not an enum value, and then casting to the enum value.
