Sprites don't consider parent's position?

[Xeonzinc]

Hi,

 

I've been using sprites but they don't seem to following the normal rules of being based off the parent objects position?

 

I've made a quick example here to illustrate:

Essentially the case seems to be:

• A sprite can have another sprite as it's parent, but won't incorporate the parent's position

• A sprite can have a mesh as it's parent, but won't incorporate the parent's position

• A mesh cannot have a sprite as a parent

• A mesh can have a mesh as a parent, and the child correctly follows the parent

 

Is this correct? I was under the impression all objects with position should follow the parent:child positioning?

I'm assuming it has to do with a sprites inside a manager all being the same mesh.

This seems like it would limit their usefulness somewhat.

 

I suppose i could create my own function to constantly update the sprite world position based on my own defined parent and local position, but it seems inefficient.

 

Anyone have any better ideas?

Because sprites are based on a different part of code they do not interfere with meshes. I think I can easily add a parent property on a sprite to inherit from another mesh or sprite position but is it really an important topic?

[Xeonzinc]

Probably not, I just assumed sprites would have a parent property like lights and cameras etc. so was a bit confused (I should check documentation more in future)

 

My reason for asking was to add a sprite-based health bar to a unit (with the sprite cells offering a convenient way to set the health level with some nice 2D graphics). I think the best option will be to switch to using a plane and write a function to select the image 'cell' with U/V offsets/scales.

Well, I'd like to use sprites as part of a dynamic board. Having them all move together once placed would be a lovely thing.

Never mind. I went with flat meshes. They will be superior when rearranging the board, anyway.
