更新列表中的每个项目

Question

So, I've created a list with 2 objects in. I want to make sure they both update.

public static void Update(GameTime gameTime)
{
    Player.Update(gameTime);
    Seagull.Update(gameTime);
    foreach (Seagull seagull in seagulls)
    {
        seagull.Update(gameTime);//Here is where the error is. 
    }
}

This is the error observed Error

Help would be greatly appreciated.

Answer 1

the error tells us that seagull.Update is a static method, which means it can't be called for each seagull, only for 'seagulls' as a whole. I suspect you don't want this, and will need to stop it being a static method (by removing the static keyword).
