  • How can you animate a sprite in SFML (C++)

    - by Apoc
    Lets say I have 4 images and I want to use these 4 images to animate a character. The 4 images represent the character walking. I want the animation to repeat itself as long as I press the key to move but to stop right when I unpress it. It doesn't need to be SFML specific if you don't know it, just basic theory would really help me. Thank you.

    - by Mix
    Hi! I need to implement HorizontalScrollView which is scrolled to predefined positions (similar to Home behaviour). It works with slow gestures, but does not work with flings. I hooked to View.onScrollChanged() and it is called when scrolling happened, but I can't determine when scrolling ends. In theory there should be a way to say that fling is over. Is there such API?

    - by incrediman
    Hi, Let's say I have a string or array which represents a number in base N, N1, where N is a power of 2.

  • Is there such a tool for testing

    - by kjack
    Say one has a structural codebase where lots of the code is in GUI control events and has no tests. So such code, to my knowledge is not suitable for unit testing Is there a tool that can test each routine automatically replacing references to code elements external to the routine (be they functions, variables or GUI controls) with appropriate mocks(?) and record the results in a database for later comparison after code changes? So the testing program would have the duty of writing, running and reporting tests with minimal intervention?
