Suggestion: CIGI/DIS debug help

[Amerio.Stephane]

Hello,

To help debug our scenario providers, I would like to get something along this features:

- for each CIGI or DIS entity, call a user-defined callback to overlay a text onto the entity. Typically, the callback could be something like "void fct(entity*[in], string*[out], color*[out])".

Note: currently, I couldn't find a way to simply iterate over all defined entities and do the 3d text overlay myself.

- be able to remove all entities (so leftover entities, ie entities which are no longer being moved by the simulation, can be cleaned away)

Thanks!

If I understood you correctly you want a method that will return all entities in the scene. Am I right?

This is already planned for 2.10+.

Thanks.

This would also be a great addition (getting all CIGI entities, and with another fct all DIS entities). But my first need is just to overlay a text on entities. Of course, getting all entities would allow me to write code to add 3d text myself, but I think this feature would be helpful to other users and can be generic enough to be found "out of the box" in Unigine.

With our legacy IG, there was a simple API we could call that looked like this:

cigi->setTextOverlayCallback( &textCallback );

void textCallback(CigiEntity* entity, String* text, Color* color) {
	*text = entity->name();
	*color = Color::red;
}

Setting a nullptr callback would just remove all texts. There could be a different callback for Cigi, Dis, Hla for example, so we could distinguish the text/color with the entities internal data. Of course, this is still just a suggestion you can improve on :)

Okay, we'll discuss this with the team. 

Thanks for the feedback!
