I am trying to keep the object in the screen/gameArea and i simply can't.



I use these if statement and it prevents the object from moveing to the right side



if player.position.x > gameArea.maxX - player.size.width/2 {



    player.position.x = gameArea.maxX - player.size.width/2



}


but i can't apply to the other side because it crashes



if player.position.x < gameArea.maxX - player.size.width/2 {



    player.position.x = gameArea.maxX - player.size.width/2



}

    What is the error message from the crash? That should provide some useful information, or at least indicate what line the crash is on.

  • Your second example uses gameArea.maxX as well, when it probably should use gameArea.minX. This shouldn't necessarily be the source of the crash, but if there was a floating point error then both of them might fire in the same loop.

What visual should I use to simply compare current year value vs last year in Power BI desktop

Image
0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
