An Adapter determines two things:
1. How external Unity components like MeshRenderer, TMP_Text, and Colliders affect gameObjects using SizeType.ComponentSize.
2. How layout results will modify those a gameObject's components and localScale.
Flexalon has built-in adapters for:
| TextMeshPro.TMP_Text | The component size is the size of the text. The RectTransform is resized to fit the text. The gameObject scale is set to 1. |
| RectTransform | The component size is the size of the rectTransform. The gameObject is scaled uniformly where possible, depth scale is 1. |
| MeshRenderer | The component size is the size of the renderer local bounds. The gameObject is scaled uniformly where possible. |
| SpriteRenderer | The component size is the size of the sprite. The gameObject is scaled uniformly, depth scale is 1. |
| Collider | The component size is the size of the collider local bounds, which depends on the type of collider. The gameObject is scaled uniformly where possible. |
| Collider2D | The component size is the size of the collider local bounds, which depends on the type of collider. The gameObject is scaled uniformly where possible, depth scale is 1. |
Implementing a custom adapter
To provide your own sizing strategy, implement Adapter and call:
Flexalon.GetOrCreateNode(gameObject).SetAdapter(yourObject);
Measure
Bounds Measure(FlexalonNode node, Vector3 size);
| node | The node to be measured. |
| size | The size set by the Flexalon Object Component. Update any axis set to SizeType.Component. |
| Return Value | The measured size to use in layout. |
Call node.GetSizeType() to determine which axes should be adjusted. Return a bounds that includes the passed in size and the auto size.
UpdateSize
Vector3 UpdateSize(FlexalonNode node);
| node | The node to be sized. |
| size | The final layout size. |
| Return Value | The desired scale of this gameObject. |
Update components on this node's gameObject to match the passed in size. Do not adjust the Transform component. Return what the gameObject's scale should be in local space.
