Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Second Touch on Screen riggers onRelease Button.

I'm developing a game for the IOS platform and the weirdest thing is happening. I have 2 buttons on the screen. One of them the player must hold down while swiping. But after he swipes only on the first time it triggers the on Release event of the button. I would post this as a normal question but this behaviour seems like a bug.

Here are a couple of Screen Shots. If more are needed just let me know. alt text

Hello LuLima,

I was unable to reproduce this issue on our end. I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?

  2. If so, could you provide a detailed set of steps to reproduce this issue on our end?

  3. Could you provide the exact device that you are testing on (Example: iPhone 6)?

  4. Could you provide the exact OS that is being run on the deviece? (Example: iOS 9.0.1)

  1. I believe so

  2. Simply create a widget with a button that changes a boolean when its pressed and change it when its released.

  3. Add the widget to the viewport

  4. On the input touch node print that boolean when you touch the screen.

I'm running it on a iPhone 6, IOS 8.4

I'm investigating if it is related to focus on the widget going to the button and with that i'm losing the button pressed. Not sure if its that.

If it helps out investigation, i tried changing the is Focusable boolean of the button itself to false and the problem stopped. I don't know if that is an expected behaviour or struck of luck. Hope it helps
