C# and iPhone dev. question

Unity Engine

Hi,
going through initial learning phase, I am trying to learn C#/Unity/iPhone dev.

I managed to get the initial things sorted (Apple certificates, xcode setup, mono dev setup with Unity, Unity set up with bundle identifier… now I have Unity 3 able to build and run with app going to my iPhone4). as a noob I am happy that at least I got all of this sorted for now

To get going with Unity/C# combo I was following 3DBuzz simple shooter tutorial, and it is just fine if I use build settings for Mac Standalone. no probs. But what I am really interested in is iPhone development so I am using the Simple Shooter tutorial as a reference and converting what I learn to iPhone iOS development which so far at least for player control in c# means using different code, well of course the iphone does not have input via arrow keys and asdw keys, so I went on using Vector2 touchDeltaPosition / input.GetTouch, etc… this way I can move my cube around with my finger.

What I can’t get to work for now is having my cube to wrap from one side of the screen to the other when it goes off screen. I tried the code from buzz which ‘logically’ is simple to understand (and it works if I build for Mac) but it doesn’t work if I build for iOS, unity iOS does not like Vector 3, the arguments , etc…

//wrap
		if (transform.position.x <= -6.2f)
					transform.position = new Vector3(6.2f, transform.position.y, transform.position.z);
			else if (transform.position.x >= 6.2f)
					transform.position = new Vector3(-6.2, transform.position.y, transform.position.z);

ERROR MESSAGE: Assets/Scripts/Player.cs(17,123): error CS1502: The best overloaded method match for `UnityEngine.Vector3.Vector3(float, float, float)’ has some invalid arguments

That same code was fine if building for Mac standalone

So I tried different solution using Vector 2 (x, y). Using touchDeltaPosition instead using transform.position with overall different code of curse etc… but what I came up with didn’t work.

  1. is it just me (as in noob) or is it the case that when coding for iPhone there are things that cannot be used for example vector 3 or transform.position.x - Is there somewhere in the documentation info about what (if any) c# cannot be used for iphone with indication of correct way to do it.

Not sure if what I just wrote makes sense but if it does, thank you for your help :slight_smile:

your -6.2 is missing f at the end. as you wrote it its a double.

and its interesting that this should have worked on the mac, I’m near 100% sure that it didn’t do it there either if you tried it this way but you potentially extended it for the device with copy paste :slight_smile:

c# on the device works the same as on the desktop normally, aside of reflection not working.

Hi… wow, I checked my typing a few times to make sure it was not going to be a silly mistake like this… there you go, that’s what happens when you work for the first time on a thing for a few hours no stop… you make dumb mistakes.
It did work on the mac build, I guess when I created the project for iOS and re-typed the code I missed the f and started to mess things up

Cheers
