clamp method
Clamps the given vector so that it falls within the boundaries formed by a rectangle between the origin (0, 0) and this vector.
Implementation
Vec2 clamp(VectorBase other) {
int newX, newY;
if (x < 0) {
newX = other.x.clamp(x, 0).toInt();
} else {
newX = other.x.clamp(0, x).toInt();
}
if (y < 0) {
newY = other.y.clamp(y, 0).toInt();
} else {
newY = other.y.clamp(0, y).toInt();
}
return Vec2(newX, newY);
}
