I’m setting textures multithreadedly. Here’s SetTextures():
public void SetTextures() { Texture = _hitObjectTextures[Parent.Parent.InputRetriever.Keys][Key] ?? Texture; Offset = new Vector2(-Texture.GetWidth() / 2f, -Texture.GetHeight()); if (Note.IsLongNote) { HoldEnd.Texture = _holdEndTextures[Parent.Parent.InputRetriever.Keys][Key] ?? HoldEnd.Texture; HoldEnd.Offset = new Vector2(-HoldEnd.Texture.GetWidth() / 2f, -HoldEnd.Texture.GetHeight()); var holdEndPosition = When(Note.StartTime) - When(Note.EndTime); HoldEnd.Position = holdEndPosition; HoldEnd.Visible = true; HoldBody.Texture = _holdBodyTextures[Parent.Parent.InputRetriever.Keys][Key] ?? HoldBody.Texture; HoldBody.Offset = new Vector2(-HoldBody.Texture.GetWidth() / 2f, -HoldBody.Texture.GetHeight()); HoldBody.Visible = true; HoldBody.Scale = new Vector2(1, Mathf.Abs(holdEndPosition.y) / HoldBody.Texture.GetHeight()); } }
