Count up / Count down

[Sam1975]

I have a counter that has a minimum value of 0 and a max value of 100.

What I want to do is:
Press "space" start counting up to 100
When it hits 100 count down to zero
When it hits 0 count back up to 100

Now I have 2 event groups one for counting up and one for counting down and I turn off and on the event groups depending on if I need to count up or down.

This is working fine but I wonder if there is an easier way to do this that I don't know <img src="/center/images/graemlins/smile.gif" alt="" />

thx,

You may not even need two seperate program groups for this: first you'd have a counter object with a minimum value of 0 and a maximum of 100. Then, a line which reads

Upon pressing space bar
+Every [time increment]
*Add 1 to counter.

When counter= &lt;100
+Every [time increment]
*subtract 1 from counter

When counter =&gt;0
+Every [time increment]
*add 1 to counter

That should give you a start. And remember, sometimes you indeed want the best solution, not just a quickie fix. Sometimes the extra effort will pay off in the long run.

I don't think your solution even works or maybe I didn't explain what I wanted the counter to do.

Once I press space the counter counts up and down by itself.

You only press space once and then after that it counts up to 100 then down to 0 then back up to 100 and on and on.

Those events won't work correctly on their own, as the counter would go in both directions simultaneously when between 0 and 100.

You would need to add an object that can store whether the direction is currently going up or down - anything will do for this, be it an active's flag, alterable value, or another counter. When this value is in the 'off' state, nothing should happen, but the space bar should allow it to move to the 'counting up' state. When it hits 100, the flag value should be changed, making the counter count down. Even though it has three states, I'm going to call it 'flag':

Upon pressing space bar
+ Flag is 0
&gt; Set flag to 1.

If flag is 1
+ Restrict actions for blah
&gt; Add 1 to counter

If counter is 100
+ Flag is 1
&gt; Set flag to 2

If flag is 2
+ Restrict actions for blah
&gt; Subtract 1 from counter

Counter is 0
+ Flag is 2
&gt; Set flag to 1

Flag is 1 or 2
+ Space is pressed
&gt; Set flag back to 0 to stop it.
