Scale Sprite around center

ResourceCache* cache = GetSubsystem<ResourceCache>();
Graphics* graphics = GetSubsystem<Graphics>();
Sprite* sprite = ui->GetRoot()->CreateChild<Sprite>("Spite");
int size = 128;
sprite->SetSize(size, size);
sprite->SetPosition(graphics->GetWidth()/2 - size/2, graphics->GetHeight()/2 - size/2);
//SharedPtr<ValueAnimation> scaleAnimation(new ValueAnimation(context_));
ValueAnimation* scaleAnim = new ValueAnimation(context_);
scaleAnim->SetKeyFrame(0.0f, Vector2(1.0f, 1.0f));
scaleAnim->SetKeyFrame(10.0f, Vector2(0.5f, 0.5f));

sprite->SetAttributeAnimation("Scale", scaleAnim, WM_ONCE);

The above code scale the sprite with it’s left-top corner position fixed, how to make it scale around the center?

I think scale then move approach should fix your problem.

Adding a Position attribute animation works.

I’m confused , for Sprite, the “Position” attribute animation does not accept IntVector2, but only Vector2.
