Confused about Touch1, Touch2, etc.....

gyroscope

I ran one of my "sleeping" projects on the iPad viewer today, a top-down shooter. It has joystick control and fire button. Anyhow, I noticed that I can control the player at the same time as press the fire button, both working fine at the same time. Both these actor have when Touch1 is pressed.

I always thought that I'd need Touch1 and Touch2 for both to work at the same time.... so if I don't, what is the purpose of more than one Touch attribute in Devices then? (Using two fingers to enlarge and reduce, I guess, but if touch1 works on two controls at once , still why do we need more? Anyone can explain please?

Your Sincerely

Gyro ,
Touch is pressed is not linked to a specific Touch # and will register regardless of how many fingers you have on the screen .
We need Touch1 and Touch2 and Touch3 etc , mainly for multitouch constrains , so 1 actor can be constrained to 1 finger , and another actor to a different finger .
Also , we need "touch count" for multiple proposes , one of them can be to determine the finger # that currently pressing the actor.

Hope that this clarify things a bit

To my aid yet again, Roy! Thank you, and I understand now. :-)

so this is the way tap tap works?

@GL

if you mean double tap, no. You would create a attribute for that and record the amount of taps within a certain time period.
For Example:

Rule=
When touch is pressed
- change attribute tapCount to tapCount+1
-timer after .5 seconds change attribute tapcount to 0 (run to completion checked)

Rule=
when tap count=2
-do double tap stuff

What there referring to in this thread is multitouch.
Example:
How many fingers are toucing the screen at once, position of the first finger and the second finger, ect.
