Creating a Basic iOS Game

[Bogey]

Thanks for the tutorial Tom Havlik. It's great.
Onoa: I did what you said I should do with the class extensions and the .ini file, but my control sticks are still nowhere to be found. Could there be anything I may have forgotten to do that is absolutely crucial?

EDIT: nvm, problem solved

[kite212]

thanks a bunch for these tuts it has helped a bunch for getting started, does anybody know where i can get some insight on the Mobile Placeable Pawn and linking that to the controls i have made in unrealscript??

[maverick976]

With the edition of the joysticks this works nicely. However, I would also like to request a tutorial on how to add a side-scroller camera to this code. I want to do it in unreal script, so its there for my entire game. I believe you have to redo it for every level if its done in kizmet. I have tried converting the code supplied for the various camera tutorials to the mobile solution and I just can't get it working.

A big added plus would be an example of how to control the side scroller with custom buttons such as an old Nintendo controller, etc. Thanks again for this solid tutorial!

This is actually a really great idea for a tutorial. Someone on my youtube video for this asked when I was going to make a new one, and I suppose I might do it over this. First step will be setting up the camera, and then getting horizontal joystick movement? I mean, you could use the up direction for jumping, but it'd make more sense to have a button for that. Any kind of functionality I'd imagine the vertical direction of the joystick being would be out of the scope of a tutorial.

Thanks for the great suggestion. If you're wanting to throw out a couple features you would like to see in there, please feel free.

[maverick976]

That would be great man. I picture something that would work like old school mario (with guns) :0). Left and right arrows on left side and two buttons on right for jumping and shooting. I guess you could have up and down buttons for weapons changes and squatting behind objects.

Just not sure how that would scale to the ipad in landscape mode, but I guess it wouldn't be worse than the joysticks for the current mobile game.

Thanks. I know many would appreciate a tutorial somewhere along these lines. I have seen people all over the web looking for side scrolling features or really anyway to control the camera with the mobile toolset without kizmet only solutions.

[Tom Havlik]

Yeah, kismet seems to be popular for entire game tutorials, but it's really completely impractical. I really want to incorporate the joystick into this, though, so I'll have joystick control movement and the down direction crouch the player. I'll throw in some notes and hints as to program a little camera move for looking "up" (similar to the Sonic side scrollers where if you hold up for a moment, the camera moves up just a bit.) I'll have the camera move down upon crouching much the same.

The mobile input system scales quite easily for landscape/portrait modes on different systems. ALWAYS use relative layouts and you'll be fine.

thanks for the tutorial.

Great stuff Tom, really helped me understand alot about how udk works with such a simple tutorial...

Hey Tom,

Two questions for you sir, if you had a minute.

1.) When I click on the "Mobile_Previewer" in order to preview my game, I still get a message stating that scripts are outdated and if I'd like to rebuild. I've fully recompiled in Unreal Frontend, so I'm not sure what I've done wrong here.

2.) When I do fully recompile in Unreal Frontend, I get a warning stating this:

Warning, Can't find files matching C:\UDK\UDK-2011-03\Binaries\Win32\..\..\Development\Src\MyGame\Cla sses\*.uc

Again, have I missed a step/done something wrong? I still get a full succeed at the end of everything, but this is still popping up.

I'll continue to mess around and see if I can figure out anything, but I wanted to post and ask for your expertise, if you don't mind. Thanks again for the great tutorial. Look forward to your response.

[aZzy]

for your first question, are you sure you have told the engine to compile your scripts? and if so delete your config file and recompile again and it should work.

as for your second question, there is a space between Cla sses... whether that typo was made when posting i am not sure.
Otherwise, You have compiled without saving any files in there.

[Insipidus]

Thanks for your response aZzy.

I'm pretty sure I told the engine to compile my scripts. It says ---MyGame - Release----- at the top like in the tutorial.

I removed the Config file in MobileGame folder completely and recompiled, and this seemed to remove the warning I was receiving (I copied and pasted that warning directly into my post btw, so there shouldn't have been any typos, but I'm looking into that space anyway. I noticed that too.). The Previewer doesn't come up at all now though and I get an error asking to report the issue to Epic.

Did I remove the Config file from the incorrect folder? I've put it back in MobileGame (just threw it on my desktop for the time being) and it's back to how it was before, asking if I'd like to recompile when I attempt to open the previewer. Also still get the warning message in Frontend, without the space in Classes btw, but everything seems to succeed. Removing the Config file from other folders doesn't seem to be the right thing to do, but please correct me if I'm wrong.

Finally, when following that extension for the warning, I cannot even find a folder for that. I get into Win32 and then become lost with the "\..\..\" business. Again, it still succeeds, so I'm not worrying about it too much.

I feel like I'm close here to getting the desired result. Hopefully these issues can be resolved. I'm sure it's something simple that I've messed up.

Thanks again for the help. I really appreciate it.

[Insipidus]

Oh, and MyGame is not showing up in "Game Type For PIE" inside the editor either. Not sure if that information would help at all.

I can start a new post for this. I don't want to take away from the tutorial post. Just figured I'd type here in case others have similar issues....

[Insipidus]

I figured out my issues. Created a separate thread. Hopefully this will help someone.

Thanks, Tom. It was a great intro tute. I have encountered a problem, though. Its probably something I've done but I got this error after I tried to compile all the scripts. Has anyone else gotten this or know what it means?

I would copy over that file from a clean install .. or perhaps even the entire Engine\Classes folder, because if that file got duplicated, who knows what else might've

[iio]

Yeah good point. I've been tinkering around for a couple of days and shouldn't be surprised that I've ended up in this position. I'll just do a clean install as I haven't any work I'll miss. Cheers.

[blakedaze]

great.. thanks for the very informative information.

[utech]

I think that there is some differences in setup MobileGame in : UDK-2011-08 version, there is no Mobile Game folder in the root of the UDK folder ?
So how to setup mobile game project in UDK-2011-08 version ?

Thanks

EDIT:
it's all the same, now in August version of UDK all ini files are both for PC and Mobile.

Hello i get an error with "SetMeshVisibility(UTPC.bBehindView);" in my Pawn class when trying to use this camera example.

[vignesh.vs.in]

I am able to get my game up and running in mobile previewer but when i deploy the game on my iphone the game doesnt use my custom gameinfo class . all i get is my map with no interactivity.

Stuck on this problem for 2 days now. help plz.

Edit: i checked and recheck the ini configs too.

[Vawx]

Check, in the editor, with your map open: View -> world properties -> Game type

Change these to your gametype.

If you have done this already, try to provide more info.
