# EB Guide

kick start: P27 - P35: Jump between different screen using **++Transition|Inside the Properties of image, Add Widget feature properties -> touchShortReleased -> 
function(v:touchId::int, v:x::int, v:y::int, v:fingerId::int)
{
 fire_delayed 0, ev:"turn_on"()
 true
}
++**


## Concepts

* **Widget**: Any object in the view state? could be image, could be text (called **"label"**)
* **State**: means the "state" of the machine. Such as initial state, view state.
 * **View**: is also a widget, resident under view state.
  * **image**: is also a widget.
 * **transition**: watch for a trigger signal. Trigger signal could be send from a image, etc.
* **Model elements**: 概称，大概是指放在Navigation menu中的所有东西
* **VTA**: view transition animations
* **Model and Appication**: use datapool to communicate. Model is the stuff made in EB guide. Application is something outside? so the datapool act as a API?
* **Datapool**: Act as an API. But also used to store data which is only used in either EB guide model or applications.
* **Events**: a user operate event. e.g. ''%% ev:"turn_on"() %%''in the Touch released Widget feature properties. An event could contain parameters.


## Model elements (showed in the navigation bar)

* State
* View
* Templete
* Event
* Datapool Item
* Script
* Property
* Transition Animation

## Use image file as button.

* Add image files to the $GUIDE_PROJECT_PATH/<project name>/resources directory
* Use image files the same way like shapes.

<wrap lo>EB guide supports 9-patch images (P65)</wrap>


## Display Overlay Window (Dynamic State Machine)

* Q: What's the meaning of checkbox "Dynamic state machine list"? A: Checking it will make the object able to be stack dynamic machine on.

## 3D file

Only the OpenGL ES version 2.0 or higher and DirectX 11 renderers can display 3D graphics. The supported
3D graphic formats are COLLADA (.dae) and Filmbox (.fbx). For best results, use the Filmbox format.

It is possible to import 3D graphic files in EB GUIDE Studio. After you have imported a 3D graphic file in EB
GUIDE Studio, in $GUIDE_PROJECT_PATH/<project name>/resources, you find a subdirectory. Meshes
as defined in the 3D graphic file are imported as .ebmesh files. For details, see section 6.1.3, “Import of a
3D graphic file”.

**Task**: research if there is an easy way to convert .ebmesh (or .jt? can't remember) files to .fbx files. ++++ Result|Hello Carsten,

Here are 3 ways I found to convert .jt file to .fbx file used in EB guide.

1)	Use the 3D software Rhinoceros.
Rhinoceros is a Rhino is a 3D modeler software and seems to be able to convert jt file to fbx file
According to the discussion in Siemens community website:

   ….  generally the best way to convert anything from nurbs (eg. jt file) to polygons is by importing the STEP file into Rhinoceros and save to a polygon format like FBX. That software gives the most control over the quality of the conversion, as well as preserving the NX body names….

There is a 90 days evaluation version of Rhinoceros, so we can try this first,
https://www.rhino3d.com/download


2)	Order from web
There are websites like https://cadmonster.org/ that can take the order to covert 3D files. 


3)	Use commercial software
There are commercial software specified to convert 3D files. One software from Okino Computer Graphics is recommended here: https://www.rhino3d.com/resources/1357

Demo software exits but it will make some “watermarks” on the exported files. 

Cheers,
Sirui

## Script Language

When to use? to fire events when click image, etc. to write datapool items. to modify widget properties.

### namespace

- ev: events
- dp: datapool items
- f: user-defined actions (foreign functions)
- v: local variables

### Access the properties of widget
If a script is part of a widget, it can access the properties of that widget. EB GUIDE Script creates a variable called ''v:this'' to access the properties using the dot notation

[[EBguide Frequently used code]]

````fire ev:mouseClick(10, 20); // "mouseClick" has two integer parameters (P78, there are more command like "cancel_file and match_event")
````
