Tutorial How to make 3DS Games with Unity

[placebo_yue]

I'm getting issues with the button examples in Unity, I get this error:
"The type or namespace "N3DS" does not exist in the namespace "UnityEngine". Are you missing an assembly reference?"

It seems like the libraries aren't linked right, is there anything I can do?

If it fails on every single script you're in trouble. Perhaps reimport the SDK and such. Are you using the right unity version?

I think you did not change the target platform to 3DS

Hello, I get this error when build the game:-

Does someone here has documentation for unity 3ds?

Does someone here has documentation for unity 3ds?

No, I use information and tutorials from Internet and from Unity's tutorials to make 3DS games

Hey, I have bug with render queue, can you help

 

[syelan34]

I think you did not change the target platform to 3DS

Yeah, I only realized that recently. Thanks for the help! It works perfectly now

There is a bit in the unity app itself (at least in the version I have, that being 5.6)

 

[syelan34]

Does anyone know how to get gyro input? The manual page says it's supported (version 5.6, Help>Manual N3DS, Input section), but in the scripting reference (page is in the same spot) I can't find anything about it. All the other input modes have documentation, just not this.

But hey, why there is no shadow with 3d game? Can anyone help?

realtime shadows are too expensive for 3DS. Bake your scene lights, use reflection probes, and such. If you insist on having realtime shadows, try different shaders, some will give you shadows, at the cost of the game running very slow

nevermind it works just fine now this is great

How? I tried but no result

Touchscreen should work with normal buttons as if the stylus were a mouse clicking. Nothing to configure, code, or do.

If you want some more complex mechanic with swiping or whatever that might be a different thing.. although i don't think it'd be hard to code. It does seem to pick up on normal mouse events, so it should be nearly as doing a swipe for mobile, or a mouse drag for PC

It works on the PC in unity project, but after build the game it just doesn’t, both emulator and real N3DS

so, is developing with unity on the 3ds still really taboo? because i have been beating my head onto it for a bit and it wouldn't make sense to create a game without the ability to share anything about it

 

[derIbrahim]

Can someone help me. The lower screen is duplicating to the upper one

 

[placebo_yue]

Can someone help me. The lower screen is duplicating to the upper one

you gotta set the cameras to top and bottom screen. somewhere on the inspector in the camera settings i believe

 

[derIbrahim]

Ok i somehow managed to fix it. I don't even know how. But now a cube that i placed is rendered black instead of white. Any idea as to why that happens?

Does anyone know why the game crashes my 3ds? It crashes with the following exception:
