AS3 - CS5 - iOS Game - Main character won't jump when (b_button) is pressed.

Hello all,

Thank you for taking the time to read and try to help me out with this small issue. I'm not a programmer, I'm more of a designer with aspirations of continue learning "logics". Well, enough of that.

My problem is as follow: When I deploy to the iPhone 5 for testing, app installs all good, runs all good, and all buttons work (SEPARATE) all good. In this platformed game I'm developing, when the user touches the (l_button or r_button) left and right, the character moves just fine. But if the user is holding the left button and ttys to use the B button for jumping, nothing happens. It doesn't register at all. no trace, no actions, no nothing. Its like the device can only handle on "press" at the time. I'm sure the problem lies somewhere in my novice code. So please if anyone could help me with this, I would greatly appreciate it.

Thank you!

Mouse events only support one touch (there's only one mouse). Once you need to use more than one touch at a time, mouse events won't work.

You have to add code for multitouch. Touches mostly work the same as mouse events and there's code to interpret touches. You'll get a touch id for each touch.

gotoandlearn.com has video tutorials on multitouch input mode.

Hi,

At first glance it looks like you need to change the keyhandlers from

else if(this.key

to just

if(this.key

as it will only regsiter one at a time using the else if's,

Edit,

sorry Moot, I jumped in the wrong one, when I know nothing about ios / air stuff

No worries about posting on my posts. The AS3 is exactly the same except for the stuff that relates to the device - like touch. If you can fix the code, fix it.

Thank you for your input moot. I'm looking into it.
