I just zoomed in to 6400% and could edit the sprite just fine. I think the problem is in your computer.

Do not use the plugin

use "blend mode" and the "action" in construct 2

That looks great. Can you provide an example capx?

Can you explain that?

Sorry, can't help you with that.

And also, if I am correct 1200px*800px is a (3:2 in aspect ratio) will it hurt if I use a different aspect ratio like (16:9) 1280px*720px ?

It won't hurt, just test it beforehand how you app looks like on different screen sizes. It is also recommended to use the scale outer fullscreen mode detailed here:

It depends on your game and your target devices. If you are making a pixelart game, then you should use point sampling and upscaling. Your game and your assets will be smaller in size, and you put less weight on mobile GPUs. In the end it will run on more devices. On the other hand, if you don't want to go with pixel art, then I think downscaling would be better, because then you use higher resolution assets, so your game won't look bad on bigger screens (like 10" tablets). I'd suggest, in that case go with what BackendFreak said in the mobile resolution topic:

I personally pick an average resolution (1200x800) and use images of the 1.5x sprite object size. It scales nicely both ways.

I just did a quick testing. It only works if you have the sprite you want to set already on your layout.

It's not porting - it is more like wrapping. So most of the games could be published on mobile, but it all depends on stuff like how big and complex your game is.

Yes, and you'll have to optimize it from the beginning. Testing a lot, etc..

This will come useful. Thank you.

Then I suggest you make an example capx and fire a bug report. There might be something broken.

Yes, you will have to wait for C3. Also, yes we have to wait for a while, but Ashley stated recently that it's being worked at, so don't worry. It's not abandoned.

Kids these days lose focus so quickly that by the time you were halfway through coding up something simple in a traditional language you would have lost about half of them at least.

Yes, this is true. A few years ago it was that an average student can focus for about 20 minutes before they need to take a break (the teacher would tell a short story, ask them something interesting, etc..). Nowadays that focusing time is much less. The kids grow up with their attention divided so they will divide their attention in class too and can focus for shorter periods.

From the manual:

Set cursor from sprite

Set the cursor image from a Sprite object. This is preferable to setting a sprite to the mouse co-ordinates, because the input lag is significantly lower. Various limitations apply: the sprite image is used as it appears in the image editor, not taking in to account size or rotation in the layout; the image cannot be too large (64x64 is usually the limit); and support varies depending on browser and OS.

Also, here's Ashley's answer for this in a different topic:

saiyadjin Personally, I'm really interested in your results. So if you can do some performance tests after your fixes, please post it here. I'll check this topic very often. I think it's great that you do these experiments/fixes in your free time. It might be important what you discovered, it might not, but I think it's worth finding out.
