integer cast function for the math.VectorX

[XFajk]

I was thinking if making a method that turns floats in the Vector to integers would be a good addition because in my last project I found my self doing pygame.Vector2(int(other_vector.x), int(other_vector.y)) and something like other_vector.copy().int() would maybe be more readable

also I can and would want to implement this I am just making an issue to get it approved that I can add this and also I to link the pull request to this issue

It is technically not the same thing, but have considered using the round() function instead? It returns a vector with each component rounded. (1.2 -> 1, 2.6 -> 3)

maybe the best approach would be to implement normal logical round like you said but also a floor and ceil methods

@XFajk the round() functionality is implement trough __round__ magic method (95% confident) so the best course of action could be to implement the __int__ method, but there might be reasons it wasn't done before that I'm not aware of.

class Custom:
    def __init__(self, any: float):
        self.any = any

    def __int__(self):
        print("int called")
        return int(self.any)

print(int(Custom(2.8)))

(example, for Vector2 it would be needed to be done in C)

@damusss I could just try to implement the int method if some unrelated tests fail I will just close the issue

Hey @XFajk, note that you would not use the __int__ method to implement this behavior because __int__ must return an integer.
Better options would be __trunc__, __floor__, and __ceil__. However, that the math module docs for these all say that the method should return a valid number.Integral value.

Personally, I don't think any new implementation is needed, because there are ways to get similar behavior:

• All pygame functions that take pixel coordinates automatically truncate the decimal
• You can floor (note that your examples truncates) a vector with floor division by 1: pygame.Vector2(1.3, -1.6) // 1, giving a new vector
• You can round a vector with round(), giving a new vector
• I think the provided use case is uncommon. Feel free to elaborate more on your use case.

@aatle yeah you right I tried to implement it but I ran into the int can only return a integer problem and I dont see a better way to implement this that would feel weird
