Struct bevy_core::FrameCount
source · pub struct FrameCount(pub u32);
Expand description
Maintains a count of frames rendered since the start of the application.
FrameCount
is incremented during Last
, providing predictable
behavior: it will be 0 during the first update, 1 during the next, and so forth.
§Overflows
FrameCount
will wrap to 0 after exceeding u32::MAX
. Within reasonable
assumptions, one may exploit wrapping arithmetic to determine the number of frames
that have elapsed between two observations – see u32::wrapping_sub()
.
