Change entity color based on entity attribute value

[steve...@gmail.com]

Hi,

I'm wondering if anyone knows how to change the entity color based on the attribute value assigned by an assign module? I found an old post with an example where the entity shape changes after assign module using SetGraphics module, but didn't see any place I can modify the color. It's appreciated if anyone can provide a simple example.

Thanks,
Da

Da,

Save a separate copy of your object with each of the colours you want to display. Then use the SetGraphics object to select the appropriate object.

Harry, thank you for the reply. Do you mean creating user defined object that is similar to SimEntity? Or create another SimEntity with its Colour Keyword (somewhere I haven't found yet) set to what I want? Please excuse me for those naive questions as I just started using the software. If you can provide an example that will be much clear to me.

Thanks,
Da

Da,

If your object is an imported image or 3D asset, then you must modify the colour externally and re-import separate versions. The SetGraphics object was intended to work with imported images, but it can work with other types of DisplayEntity.

If your object is one of the simple flat objects such as Rectangle or Circle, you can edit the colour through the Input Editor but you still need to create new DisplayEntities -- one for each colour. The following steps outline the procedure:

1. Find the shape you want in the Object Selector under DisplayModels > ShapeModel. The only ones you can use in this way are Rectangle, Circle, Arrow2D, and Triangle.
2. Right-click on the object and select "Duplicate"
3. Rename the duplicated object to something you can remember, say "Rectangle-Green"
4. Click on the renamed object in the Object Selector and select the Key Inputs tab in the Input Editor
5. Set the input for the FillColour keyword either by entering a named colour (e.g. green) from Section 14 of the User Manual or by selecting an RGB value using the drop down menu. There are other graphical options you can also set.
6. Drag and drop a new DisplayEntity from the Model Builder
   
7. Click on the new DisplayEntity and select the Graphics tab in the Input Editor
8. Click on the drop-down menu for the DisplayModel keyword and select the new ShapeModel you created (e.g. Rectangle-Green)
9. The DisplayEntity should now adopt the shape and colour settings you have made.

The above seems a bit complicated but that is only because I have spelled out each step.
