Hi!

My game has been designed to be played with a touchscreen. But it occured to me that some devices might not have a touch screen. With a reasonable amount of work I could make it playable with key inputs. In order to automatically switch to this alternative input setting, I looked for a way to check if the device has a touchscreen or not. Unfortunately I failed to find such a command.

If I read correctly, AppGameKit would generated a mouse cursor if no touchscreen were found. However, in my specific app, that would be really inconvenient.

That's why I came here with 2 questions:
Does AppGameKit support a phone which doesn't have a touchscreen? (Or is there any "touchless" phone on which AGK-made apps work?)
Is there any way to check if the device has a touchscreen?

Thanks for your patience and your help.

No command to check for touch specifically. I found this: GetMultiTouchExists(). You can also check if keyboard, mouse or joysticks exists.

You can always code in support for keyboard and or joysticks and if the player wants he can use those. That's how I coded my game.

Okay, thanks for your help. I'm going to do as you say.

First, I'll check for hardware joystick and keyboard. If they exist, use them as default input method. If not, I'll enable the touchscreen method.

I don't think there is a way to detect it through a command. I think you have just 2 options...

1. Ask the question when it first loads

2. Work it out from the way the user interaction occurs. If teh pointer seems to move from one point to another without any transition in between, it's a touch screen. If the mouse moves with many points in between, it's a mouse.

Of course, option 2 still isn't perfect. there are other input methods (pen) and of course combined mouse / touch.
