Why is my point light script parameter being deactivated when I run unity..??
Your problem is in the line:
GetComponent<Light>();
You are setting it in the inspector, so no need to set it in the Start() method (also the Light is in the child object).
Delete that line and you're set.

I'm having odd issues trying to use Unity's Text Mesh Pro Input Field UI element. I don't actually know if the layout is causing it though.
I have a scroll view which uses a vertical layout to organize objects under the content object. Each object in the scroll view has a horizontal layout inside it which fits two input fields next to one another so essentially the Scroll view has two columns of input fields.
However I'm getting odd behavior from the input field. When I start typing it won't show the input until I've entered two characters (i.e. I type '0' and it shows nothing then I type another '0' and it will show '00'). Additionally I have some code that automatically populates the input field with default value, below is an example of how I do this:
gameObject.GetComponent<TMP_InputField>().text = numVal.ToString();
However the values never show up, but I can confirm that they are being populated by checking the inspector window while the game is running. Under the TMP_Input Field component, the 'Text' field shows the correct value but I can't see it in the input box.
I'm getting no errors or warnings.
Is it the scroll view or the layered layouts that are confusing the Input Field's script? Something else? Any advice, help, and questions are appreciated.
EDIT:
I've found that it may have something to do with the way the objects are added to the scroll view. The content of the scroll view (which has the vertical layout) get's objects added to it during run time. This is done through instantiating a prefab.
Instantiate(DoubleInputNodePrefab, contentObject.transform);
This prefab object has the horizontal layout and two children, each an input field. If I add this prefab to content window before I run the game it works fine (expect that none of my intended code works since it relies on modularly adding and removing these objects) but I can give input and it looks fine.
WORK AROUND:
I won't consider this a solution but it is a work around I'm going with for now. Using a 'normal' input field rather than a Text Mesh Pro one doesn't create the same issues and works as intended.
I need to organize a set of elements in simulink. The first method is to create a subsystem. The problem with subsystem is that the elements inside it are no longer visible. An alternative method is to create a colorized box and put it behind a set of elements as a background. It makes a lot of troubles during selection of elements.
The ideal method is to have a subsystem which is transparent but you can see the elements inside it. So you can make it large and see inside it without opening it.
What is the feasible alternative method?
Knowing that there is no support by simulink doing this, the only possibility would be to use a mask icon which shows the content. The following is a very rough prototype for the mask code:
model='s1/Subsystem';
loc=fullfile(pwd,[model,'.png']);
print(['-s' model], ['-dpng'], '-r300', loc);
image(loc);
port_label('input',1,'In1');
port_label('output',1,'Out1');
Obviously this prototype has multiple issues which must be addressed when really using the code:
Remove the hard-coded directory.
Set in- and outports automatically.
create required folder structure. (folder s1 must be created once manually)
Scale the subsystem block to make the image look good
work properly if pwd is not the directory the model is stored in
You can make use of the 'Icon Drawing Commands' of the mask parameter's tab 'Icon and Ports' :-
Take a screenshot of the logic gates you want to be visible on the subsystem (the ones with a blue background color shown in your question)
Save the picture e.g 'mylogic.png'
Write this command in the 'Icon Drawing Command' field of Icon and Ports image(imread('Pause_Icon.png'));
You're done. But yes, make sure you have the picture file in the same folder as your model or simply add the folder containing the picture on your path.
Of course, if you update the blocks inside the subsystem, you'll have to update the mask icon with the new screenshot.
I have created multipage HTML editor in which one tab has text editor. I have set the global action handler to the action bar for undo / redo actions in the source editor. Whenever I am adding something in the source editor then undo it, it is not returning the same code in the first attempt. It is completing in the second attempt. Can anyone help me to solve this issue.
In the main editor override the setFocus() method and in this method call the following method of source editor.
public void setUndoRedoActionHandlers() {
final IActionBars actionBars = getEditorSite().getActionBars();
actionBars.setGlobalActionHandler(ActionFactory.UNDO.getId(),
mUndoAction);
actionBars.setGlobalActionHandler(ActionFactory.REDO.getId(),
mRedoAction);
actionBars.setGlobalActionHandler(ActionFactory.DELETE.getId(),
mDeleteAction);
actionBars.setGlobalActionHandler(
ITextEditorActionConstants.DELETE_LINE, mDeleteLineAction);
actionBars.updateActionBars();
}
Thanks
Are you sure that you set global actions by overriding setFocus()? Look at this : https://wiki.eclipse.org/FAQ_How_do_I_enable_global_actions_such_as_Cut,_Paste,_and_Print_in_my_editor%3F
It says they need to be set inside method setActiveEditor()
The reason I guess why you are seeing it working second time is - When the first time you click your editor gets focus and setFocus is called and only then the global actions are set. Then second time it will work because the actions are now set.
In the Eclipse UI, I'd like to set the visible area in an editor. In other words, if the number of lines of my file is larger than the number of lines my editor can show then I want to specify the first shown line. My first approach was to calculate the first visible line via the selection value of its vertical scroll bar. The following link points to my initial question. Its answer explains how to set the first visible line in an editor.
eclipse ui: setting scrollbar but editor does not follow
The problem now is that my initial way of retrieving the first visible line in an editor fails in some cases: Although I verify that the active page is indeed an editor, the focus might be assigned to another page. In such a case, the following code yields the ScrollBar of a different page:
public static void update(final IWorkbenchWindow w)
final Scrollable scrollable =
(Scrollable) w.getWorkbench().getDisplay().getFocusControl();
final ScrollBar vScrollBar = scrollable.getVerticalBar();
So, my question: If editor is the reference of an active editor (ITextEditor and IReusableEditor), how to I get its first visible line?
If you can access the editor ITextViewer or its extension ISourceViewer (usually implemented by the SourceViewer or TextViewer class) you can call the ITextViewer.getTopIndex() method to get the top line index.
If your editor is derived from AbstractTextEditor (or one of its subclasses such as TextEditor) there is a protected method getSourceViewer() that returns this. You may have to add a public method if you want to access this from outside of the editor.
I want to know if there is a way to hide cursor in Windows 8 Metro mode. I found
this answer, but then I don't know how to obtain the
"unique resource id" for the second parameter of the cursor constructor (below).
Window.Current.CoreWindow.PointerCursor =
new Windows.UI.Core.CoreCursor(Windows.UI.Core.CoreCursorType.Custom, 1);
EDIT: Forgot to mention that I need to handle mouse events normally so the answer below of setting cursor to null will not suffice.
Set the cursor to a custom cursor but make it just be blank...this allows you to track it like being a normal cursor.
You can set the PointerCursor object to NULL. As soon as you move over something like a text box, it will reset it back though. So you probably need to handle mouse over events on various controls, to hide it. This all depends on your complete scenario tough.
Also, before setting it to NULL, you can save the value of the property (PointerCursor) and then when you're done, set it back.
