counter tecnique

echolm

I'm using Harlowe 2.00. I've tried to set a variable to 100 and then count backwards: (set: $SunCollission to it - 1) The problem is that this does not count backwards. What is a better counting method?

Thanks.

Just to be clear,

(set: $SunCollision to 100)
(set: $SunCollision to it - 1)

Is not working for you?

echolm

Yes, that's it.

Could you supply an example of the code that is not working so that we can debug it for you. Please use the code tag when posting your example - it's the C on the editor bar.

On the first Passage,

(set: $shiplocation to "CarvorSun")(set: $EnginesOn to 0)(set: $SunCollission to 100)

On subsequent passages, I use

(display: "CarvorSunCountdown")

On CarvorSunCountdown passage:

(if: $shipslocation is "CarvorSun")[(set: $SunCollission to it - 1)](if: $SunCollission < 1)[ (go-to:ShipDiesinSun)](print:$SunCollission)

I remember I had to add the quoted for the display macro when I changed to 2.00

You have one variable that reads $shiplocation and another that reads $shipslocation. It's also part of the if statement that decrements $SunCollission, so it's never getting changed.

I can't test it now, so that might not be the only problem, but I suspect that's all there is to it.

OH! Thanks.

echolm

That's it! Working!

Also as shown in the (go-to:) macro's documentation there should be quotes around the String containing the Passage Name being passed to the macro.

(go-to: "ShipDiesinSun")
