I need help with math for rectangular touch zones instead of circular touch zones.

Due to this thread it's possible: http://community.clickteam.com/threads/80251-Movement-in-android

touchzones.mfa

Please take a look at this example with Multiple Touch object. For the circular/spherical touch zones it uses this:

Sqr(( ( XTouch( "Multiple Touch", LoopIndex("isTouchActive" ) ) - X( "dpaddown" ) ) pow 2 ) + ( ( YTouch( "Multiple Touch", LoopIndex("isTouchActive" ) ) - Y( "dpaddown" ) ) pow 2 ) )

What exactly are you trying to achieve? You haven't really posed a question yet. Do you want a Touch D-Pad like in the example, only with rectangles?

I made an example of multi-touch d-pad, seems to work better than the one you posted there.

DaveC, I know all your examples with multi-touch and they are all good but I'm just interested in that other method too.
There are basically circular zones on the hotspot of the d-pad objects and I would like to know how to do rectangular or square zones.

The expression above is "distance" from the center of the object (assuming hotspot of dpaddown is placed in the center of the object)
distance makes for a circular zone because you basically have a "radius" from center.
If you want a rectangular zone, I would guess you just need to test a "hitbox"
(es.
Xtouch >= Xdpad - 30
+Xtouch <= Xdpad + 30
+Ytouch >= Ydpad - 30
+Ytouch <= Ydpad + 30)

This is how it works. Nice tip schrodinger!

Edit: Actually it's not working - it's still a circular zone. I guess I misunderstood your post schrodinger.
I'm unsure how to it now. Can you upload an example please?

Thank you very much .

This was the code for the circular zone:
Sqr(( ( XTouch( "Multiple Touch", LoopIndex("isTouchActive" ) ) - X( "dpaddown" ) ) pow 2 ) + ( ( YTouch( "Multiple Touch", LoopIndex("isTouchActive" ) ) - Y( "dpaddown" ) ) pow 2 ) )

The left image shows how the circular zone looks with button size 10.
Is it possible to do a square zone(middle image) instead of circular zone using a similar method/expression code?

If this is not possible, how to manually set a rectangular zone as "hitbox" which works with Multiple Touch object?

Sorry I missed your edit in previous post!

I don't see the square hitbox coded in your example, did I miss something?

I was thinking at something like this:
touchzones2_1.mfa

(see "dpadup square" behavior)

[Wodjanoi]

Now I get it. Thanks a ton!

Glad to help

of course for a rectangular zone you would just have to specify a different offset for horizontal/vertical coordinates

i.e.
Xtouch <= X +10
Xtouch >= X -10
Ytouch <= Y +30
Ytouch >= Y -30

would do for a 20x60 zone
