Simple Key on, off and on again...!

Guido

Hi, I can not get a simple operation with GS. I want to create
a button-shaped bulb. When the button is not pressed is
off, stays on when pressed. If I press it again
off.

So: button is Off > touch and becomes On.
button is On > touch and becomes Off.

You have solutions on this?

I tried this way but not working as it should:

Rule: "Actor receives event" "touch" is "Pressed"
Change Image: "Set Image to: bulb_on.png

Rule: "Actor receives event" "touch" is "Released"
Change Image: "Set Image to: bulb_off.png

thanks!

put the bulb_off in the otherwise section under the touch is pressed rule. That'll work

Guido

if you touch the button lights up, but just take off my finger and the button becomes Off , I would rather stay in On position and when I touch again the button becomes Off.

Hi Guido, the following not tested:

Attribute called onoff.

When touch is pressed and when self.onoff is true, change attribute to false, change image (to off version).

When touch is pressed and when self.onoff is false, change attribute to true, change image (to on version).

This is a neat alpha toggle method...not images but it shows creative thinking

When I want to do something like this, I use a counter. Create an attribute on your bulb actor called onOff. Then you'll need two rules:

First
When actor receives touch change attribute onOff to (onOff +1)%2. This will cause the value to switch between 0 and 1.

After that create another rule. When onOff is 0 change image to off.png otherwise change to on.png

That should work

IMO the best way to do this is to use the modulus function which is just the percent sign. Create an integer attribute called self.switch

Rule
When touch is pressed
Change attribute self.switch to (self.switch +1)%2

New rule when self.switch = 0
do blah blah
Otherwise
Do blah blah blah

EDIT: didn't read mulcahy's post closely! Like he said

good one ...even better if you call your images 0.png and 1.png you can do it with just one rule with two change attributes.

on touch
self.switch to (self.switch+1)%2
self.image to self.switch .. self.file (where self.file is a text attribute with .png)

You dont even need self.file, you can simply put:

Change Attribute: self.Image to: self.switch..".png"

strange...I tried that and it didn't like it first time around...good old GS:)

Hi scitunes, could you explain the modulus function please?
