has() in a PoolVector2Array?

In a normal Array, there is a fuction called has(), that checks if there is a value in the given array.

However, in the PoolVector2Array, I can’t find a function that does something like that.

Does anyone have an idea how to check for a value in a PoolVector2Array?

Kind Regards, sian2005

You can try with this helper function:

static func poolvector_has(poolvector, value):
    for v in poolvector:
        if v == value:
            return true
    return false

if poolvector_has(your_vector, value):

Given the official documentation, there is no such method on PoolVector2Array.

However, in GDScript, you can type cast values using the as keyword :

var vector2_pool = PoolVector2Array([Vector2(0, 0), Vector2(1, 0)])

if vector2_pool.has(Vector2(0, 0)): # will throw error
if (vector2_pool as Array).has(Vector2(0, 0)): # properly print true

Please read more about static typing here.

Using as like this will duplicate the entire array just to call has.

Beware of the performance implications this could have. While this is a valid solution, this could easily become a bottleneck if your array has more than a few dozen elements.
