addClamped()

int addClamped ( int value, int delta, int minValue, int maxValue )

inline

Overflow-safe clamped addition: returns value + delta bounded to [minValue, maxValue].

Uses a 64-bit intermediate so the addition cannot overflow int. Shared by the bounded counter arithmetic in both the client and the server.

Note

Requires minValue <= maxValue. Bounds come from trusted compile-time call sites; qBound() asserts this internally in debug builds.
