Sorry about My English.
I developed 2D Platform game using Unity and its work perfect on Android and I publish it.
when I switched platform to iOS and test it on device the player run very very VERY SLOW when it on platform, but when player jump and try to move left and right while jumping its perfect move.
Help Please
So if I understand well, this is a side scroll game ?
And the 'slowness' problem happen only when you move on the ground ?
What do you use for the movement, a RigidBody2D ?
In that case perhaps you should look the settings of physics frictions.
Say me if that help
As we all know, iOS 8 having a perspective zoom feature in the home screen which zooms depend on the angle of a device and how it moves.
I want to duplicate that feature inside my app. I found a question to find out the angle of a device here.
How can I determine the angle of the device?
Measuring tilt angle with CMMotionManager
I need to discuss the ideas to zoom the image depend on the angle of a device. Any help would be appreciated.
Edit: It is a duplicate of this question: iOS 7 parallax effect in my view controller
Thanks for you help.
That feature is called a 'parallax effect' and there is built-in support in Cocoa Touch for it. You don't need to re-invent the wheel to add that effect to your apps. Search the web for information on UIInterpolatingMotionEffect. Here, in particular, is Apple's brief documentation on it.
I need to create an app for iPad, where the client can make a signature and i can get coordinates, acceleration and pressure of touch. For draw, coordinates and acceleration no problem. but i can't get pressure. I tried with CPBPressureTouchGestureRecognizer but I didn't solve. I could also use a pen and a sdk.
Someone can suggest something to me? Can i do all with finger or it's necessary a pen? What is cheaper pen and easier sdk to use?
iPad has no hardware capability of sensing the pressure. Unless it'd be some special stylus that sends the pressure info via BT to the iPad app - you're out of luck.
Also - you'd have to calculate acceleration yourself.
I write a game in Lua with Corona SDK. After some minutes of game playing, the screen goes to low power mode (it is less lighted). How can I cause to the screen to remain in High power mode?
Set
system.setIdleTimer( false )

Ive been working with the iOS sensors a bit off late and i wanted to write an app that would accurately track the motion of the phone in space. I wanted to know if its possible to track the motion of the device and detect gestures, such as drawing a circle with your phone or even moving in a straight line.
I've been searching online about this, and i wanted to know two things:-
1.Is it possible to do this with the CoreMotion framework.
2.If Yes, what is the alternative for older devices that do not support CoreMotion. Without the double integral method using the accelerometer!
This would really help!
Any other alternative ideas are most welcome!
Thanks in advance!
As your write, you cannot do the double integral.
For gesture recognition, I would try dynamic time warping. See my earlier answer here.
