Turning bb8 into a game - tap to jump. Something up with the physics though - sometimes falls through the platforms, sometimes passes through the screen edge. What am I missing?

You're assigning all the platform polygons to the same variable plat. Only one assigned will be valid.
EDIT: Add the lines I show
pl={} -- add this
for i,p in pairs(platform) do
plat=physics.body(POLYGON,vec2(p.x1,p.y1),vec2(p.x2,p.y1),
vec2(p.x2,p.y2-10),vec2(p.x1,p.y2-10))
plat.type=STATIC
table.insert(pl,plat) -- add this
end
These additions and changes can be made to setup(). The first 2 changes, e1 and e2 will fix the sides. EDGE can be used instead of POLYGON for the platforms.

Some ideas based on the old Star Wars arcade game.
Looking to combine the two but struggling. I want to treat the pseudo 3d stuff (code below) as a background and effectively use as a canvas on top of which I run the second code. The issue is that I have introduced depth and now the second set of code intermingles with the first. Is there a way around this? e.g resetting the perspective view? I've included a simple sprite example in the code.
Also, as an extra I'd like to remove the flicker (I suspect this is when the moving sprites get too close or just behind the camera position).
Thanks in advance!

@West - the jumping is to do with the way you are skipping forward by one tile, as each one passes the camera. I haven't looked at it in depth, but it's just a matter of proper synchronisation, I think.
@West - you shouldn't draw things in 3D with sprites, use a mesh like this

@Ignatz - fab - just what I was after - I used sprites after following one of your intro tutorials - not sure why sprite didn't work but I've not really done much in 3D and not sure if I'll put in the time to learn it at the moment. Thanks again though - appreciate it!

@TokOut the reason why you're seeing a pause followed by a ten degree rotation, pause, rotation etc, is because your frame rate has dropped so low. As the rotation is set by ElapsedTime, when the frame rate is low the time between frames becomes high. The main reason for the frame rate being low I imagine is the starfield. There are a number of ways you could speed it up, but perhaps the simplest would be to draw it once to an image in setup, and then sprite the image in draw.

It was fun to make, and is pretty good fun to play too! The framerate does drop on the iPad Air when the action hots up (probably unplayable on older hardware), but not as much as I thought it would, given that the models, especially the tie fighter, are insanely detailed. That's the problem with just grabbing stuff from Blender, it's often too detailed for a game. If you spent a bit of time optimising it, and culling verts from the model, you could get it to consistent 60 fps on the Air, I'm sure.
If the force is strong with you, you can unlock retro mode!
(The tie fighters have so many verts that even in wireframe mode they look solid until you get really close!)
The wireframe shader is actually faster than the diffuse lighting shader, which is pretty cool. I might actually explore this more seriously in a project down the road, as it's a cool aesthetic, and one you don't really see right now.
Finally, I'm pretty pleased with this GitHub repo installer. It's designed to be used with repositories created from Codea's new zipped-project export feature. It grabs the correct file list from the info.plist file. It's created by the new version of my WorkingCopyCodeaClient.

@yojimbo2000 excellent - loads and runs on ipad3 but something amiss with the depth of the trench - seems to only render the trench walls very close to the xwing (as if the clipping depth is set very shallow). Might be a hardware limitation

@West or @yojimbo2000 could be winner! the others aren't bad but... They are better.
We can make voting everyone, who was here so everyone is judge, West and yojimbo2000 can vote, too. Isn't it a good idea? So then it's not like yojimbo2000 is mod and my friend, so then the votes could be more vair; if we use this system, then I vote for @yojimbo2000!
Oh yeah, forgot to say that the trench is drawn with instancing, which I guess requires an A7 chip or newer? If I have time, I'll see if I can add a non-instanced version. It's good that the error message is so specific.
Ok, I removed instancing. Doesn't seem to make any difference to the performance (I think we worked out that instancing is only beneficial when there're hundreds of instances anyway)
Rerun the installer code above to get the new version.

Super late entry, but thought I'd enter this little demo I made. It's an isometric(well, truly diametric) game where you're R2D2 exploring the death star. I was hoping to add more content(minigames, etc) but I ran out of time.
Comments
Turning bb8 into a game - tap to jump. Something up with the physics though - sometimes falls through the platforms, sometimes passes through the screen edge. What am I missing?
@West - You might need physics.continuous=true to make bullet work properly
You're assigning all the platform polygons to the same variable plat. Only one assigned will be valid.
EDIT: Add the lines I show
These additions and changes can be made to setup(). The first 2 changes, e1 and e2 will fix the sides. EDGE can be used instead of POLYGON for the platforms.
@dave1707 - doh of course! Many thanks!
I added a stormtrooper helmet:
model by matpiet, mofx: http://www.blendswap.com/blends/view/77957 Licence: CC-BY
It has a texture, but weirdly it appears to be inside out (when viewed in Blender too): all the details seem to be on the inside of the helmet.
aaaaaaaargh! Awsome!
Perhaps the details are on the inside because the storm trooper can't see out of the eyeholes.
Here's a fairly simple arcade game
And here is the code, if you want to play with it.
You need this image, saved in Dropbox as "starwars"

@Ignatz, awesome, YAY, I will lose!
Some ideas based on the old Star Wars arcade game.
Looking to combine the two but struggling. I want to treat the pseudo 3d stuff (code below) as a background and effectively use as a canvas on top of which I run the second code. The issue is that I have introduced depth and now the second set of code intermingles with the first. Is there a way around this? e.g resetting the perspective view? I've included a simple sprite example in the code.
Also, as an extra I'd like to remove the flicker (I suspect this is when the moving sprites get too close or just behind the camera position).
Thanks in advance!
@West - To superimpose 2D on 3D, do this
@West - the jumping is to do with the way you are skipping forward by one tile, as each one passes the camera. I haven't looked at it in depth, but it's just a matter of proper synchronisation, I think.
@Ignatz awesome - thanks heaps. The jumping is fine - it's the flickering I'm trying to eliminate
@West - you shouldn't draw things in 3D with sprites, use a mesh like this
@Ignatz - fab - just what I was after - I used sprites after following one of your intro tutorials - not sure why sprite didn't work but I've not really done much in 3D and not sure if I'll put in the time to learn it at the moment. Thanks again though - appreciate it!
3D is the best, well worth learning
Did someone say...
Trench run?
Haha
(Your X-wing came in handy then)
Yes, I added a tie fighter and a trench section to the obj importer, that's what the trench run thing is built with.
Combined version of Death Star trench run - big thanks to @Ignatz for his help.

@yojimbo2000 yours looks outstanding!
How to make the rotation without the mistake rotation, that he rotates ten then pause, the he teleports ten, ... I want that he will rotate in one direction and not 10° then pause then in one millisecond more 10°...
This happens:
@TokOut the reason why you're seeing a pause followed by a ten degree rotation, pause, rotation etc, is because your frame rate has dropped so low. As the rotation is set by ElapsedTime, when the frame rate is low the time between frames becomes high. The main reason for the frame rate being low I imagine is the starfield. There are a number of ways you could speed it up, but perhaps the simplest would be to draw it once to an image in setup, and then sprite the image in draw.
Behold the power of a fully operational Death Star!
Retro mode can be unlocked as an Easter (Christmas?) Egg:
Good work (better then mine) @yojimbo2000, so how to replace the
ElapsedTime * 10tag?@TokOut see my comment above, https://codea.io/talk/discussion/comment/65696/#Comment_65696
Okay then here my code:
For the sprite use this code:
You will see this:
@TokOut I've tidied it up a bit and turned into a single project. There are a couple of extra redundant lines which I've commented out and you also need to look up the reference for supportedOrientations.
Finally, I'm not really getting the Star Wars theme...
Thx
How are we judging this thing? We could do a surveymonkey vote, like last time?
Actually, I think the winner should be based on Star Wars rules, which are that all the good guys using the Force always win.
Our force is Codea, which makes everybody is a winner, for sharing and having fun with it.
Uh-oh, but what if I'm on the dark side?
My guess is that the force won't be with you
Teeing it up...how about judging it by size?
Ok, here's the installer for my effort.
It was fun to make, and is pretty good fun to play too! The framerate does drop on the iPad Air when the action hots up (probably unplayable on older hardware), but not as much as I thought it would, given that the models, especially the tie fighter, are insanely detailed. That's the problem with just grabbing stuff from Blender, it's often too detailed for a game. If you spent a bit of time optimising it, and culling verts from the model, you could get it to consistent 60 fps on the Air, I'm sure.
If the force is strong with you, you can unlock retro mode!
(The tie fighters have so many verts that even in wireframe mode they look solid until you get really close!)

@yojimbo2000, this error appears by using your xwing:
your iPad may be too old for this code
@yojimbo2000 very nice. In my 1rst attempt there was an error 'main' not found. Then i ran again and loading was ok.
Oh yeah, forgot to say that the trench is drawn with instancing, which I guess requires an A7 chip or newer? If I have time, I'll see if I can add a non-instanced version. It's good that the error message is so specific.

@Jmv38 thanks for the report, I guess the http.request timed out for Main.lua. I'll see whether I can make the installer a little more robust.
@yojimbo2000 why did you deleted my messages when they were 3 times in a row?

@TheSolderKing - that's ok, it's welcome. I was hoping for a storm trooper, though.
