first example

No, only the one card you drag gets a new position (that's what the instance variable is for). Except - this is the flaw - if you overlap with two cards, two of them get a new position - could be easily fixed, but version 2 is better and so there is no need for that.

didn't like the version I made.

So here is the better one - that doesn't have flaws

Here is a version (not the best, but works)

just make an instance variable to objCards

I'm not sure if this is your problem

if you start dragging then you store the XY as a variable and if on drop is overlapping with objCard then set position to variable.

Here are 2 ways to do it

1. Event objEnemy > is NOT "on-screen" | system > create objEnemy

Here you check if the object is on-screen and invert it. Then you run a loop for how many new enemies you want to spawn (the loop number could come from a variable)

2. with a variable

For every enemy you destroy you subtract 1 from your variable. If 0 then create new enemies and add 1 to your varEnemy

[quote:2uygutdt]Ms edge runs my game so smoothly compared to chrome and other browsers it actually pisses me off

That reminds me of some performance issues I posted before.

C2 games have troubles on 2 of my 3 PC's.

Here a lot of the time Edge runs smooth and Chrome or NW.js sucks

You can try the performance test from Ashley to see how your PC tests

http://www.scirra.com/demos/c2/sbperftest/

Here it all depends on browser and the computer

My gaming rig and the i3 laptop drop around 180 frames and score worse than a MotoX mobile

The i5 laptop 0 drops

W10 i3-5010U, 4GB Laptop - has some major issues with HTML - but otherwise a great and fast Laptop

W10 i5-6500, 16GB, GTX960, SSD Workstation - has also some issues with HTML - otherwise perfect

W10 i5-5200U, 8GB, SSD Laptop - no issues at all

Still didn't figure out what is wrong with (especially on my Skylake workstation) - when I try a test like http://www.kevs3d.co.uk/dev/canvasmark/ my computers behave like they should.

Just stumbled over a capx that could help you

You find some performance tips in the tutorial section

here some points

• Place objects using the same blend modes or effects on the same layer
• make sure all those objects are placed on their own layer
• Dont Changing Text objects every tick (specially large text objects)
• Avoid large areas of overlap between objects
• Avoid objects with large areas of transparency

and of course it depends on the computer - but if you play other games that run smooth, then it's your project.

persist layout?

There is an example if you make a new project and search for persist

There are different solutions (like helper objects that disappear, instance variables or loops that check if already used)

But the best one would be an Array. Here you randomize your Array and pull a number from it (see tutorials for Arrays)

Th easiest thing - without performance loss would be just a red sprite that gets resized (full screen)

with opacity 30% or whatever or color with alpha,

As gumshoe2029 mentioned functions would be nice to implement so you don't have to write the code again and again.

here is a tutorial that shows you how you could make it with all questions in a single textfile
