About the best you can do is pbandjay's suggestion: order vectors by their length. That is not a "linear order" and does NOT satisfy "tricotomy" (given two objects that are not equal, one is "less" than the other)- many non-equal ... Web23 mrt. 2024 · Instead of comparing vectors, you could also just check if .x == 0 and .y == 0, but even these two 0's would be temporary values somewhere in memory. In the end, it's all neglectable. Another thing you could do would be to check if the sqrMagnitude of your Vector2 is 0. If it is, then both values must be 0 as well. hujan badai adalah
