Anyone have any experience with flipped, scaled, physics-enabled sprites? I'm about to get to this bit and anticipating some issues along the way. I will be scaling then flipping then adding physics collision, automatically calculated by AGK. Does anyone if there is a right way and a wrong way to do this? I understand the commands, just need to know if there are any glitches.

Also wondering if anyone has messed with scaling the view? I need to zoom in, in the style of the original Lunar Lander, my plan was to replace the sprites and rebuild the screen. Now I see that I can zoom the viewport but don't know if this is the best way to deal with it. I would really need to use over-sized images and a <0 scale for most of the game, to get good images when zoomed in (or zoomed to 1.0). There may be memory/performance issues, I have a gridded landscape of 48x8 sprites.

The answer to the first part is, flipped and scaled sprites do just fine when making them physics-enabled.

I tried to rotate sprites with physics on, it also rotated the physics, so all got odd. A bar tried to balance itself at 45 degrees, instead of falling to the ground because the sprite was rotated 45 degrees.

I'll be scaling spaceships for a 2.5d space shooter I'm working on, but it won't have physics on.
I'm hard coding the shot damage and collisions for the ships from the minimap data. (at least, that's the plan man)
I have not played with scaling yet, but it seems that 1 is 100% and 2 is 200% original size.
I am hoping that the scale value is a float.
I'll let you know if I run into any problems (glitches) or if I figure any tricks out.

1. SetPhysics OFF for sprite

2. Manually Rotate your sprite

3. SetPhysics ON for sprite

A quick note on scaling, not that I have messed with it a lot yet. Remember there is a setspritesize command as well, so you can actually use the pixel sizes rather than a percentage.
I've yet to play with the physics, but have had an idea to try since before AppGameKit was released. So I will be using it,(or trying to) soon enough.

Scaling the whole screen I have not tried, however as long as you don't scale it too much, AppGameKit does a good job of keeping image quality up. In my shooter project I scaled up the first end boss 2x and it still looked good. I was expecting it to look quite pixelated.
I would imagine the best way for you to go is to make your main level as large as it needs to be, say 4 screens long by 2 screens high for instance. Then just scale your viewport when needed, as you scroll around it. I haven't tried anything like this yet but that's how I would attempt it to begin with.

scaling looks REALLY GOOD in agk.
anyone knows what kind of algorithm is that?

I've found that scaling down isn't so good. My screen turned into a few specks of partially linked white dots.

No I would imagine it would lose some detail especially on lines as you are using. Can you scale it up for when you are close and scale it down to min 1x when you are further away?
