When is the shininess of a stationary Pokemon determined?

Question

I want to start a new shiny hunt and this time I want to get Latios. When are the shiny determinated?
When you enter Dreamyard or when the battle starts? Thanks in advice.

Answer 1

When you battle! That's why people love to Soft-reset when up against stationary Pokemon.

Hf and GL with that! Also you're welcome

Side note: Certain stationary pokemon cannot be shiny

Although that isn't really important

I know. I can say that I'm a semi-profissional with shinies. I just asked to make sure, I was already at 120 SR. between thanks.
