Help with interpolate bug that's driving me nuts :P

Hi Saladers,
I'm using an actor to fill a progress bar by starting off 10px wide and then as the player collects snowballs the progress bar gets wider with the formula: interpolate self.width = 10+30*snowballsEaten

However, for whatever reason it isn't working.... This seems pretty straight forward but I'm not sure why I can't find the bug.. I've tried lots of things.

I'm sure that the snowballsEaten counter is going up because if snowballsEaten >= snowballsNeeded then the game stops as planned... thus verifying that snowballsEaten counter is working.

Have a look at this screenshot of my backend "code".... why isn't interpolate working with self.width? By the way, if I replace 10+30*snowballsEaten with 10+30*3 it works. So I know that interpolate can work for width..but it isn't recognizing that snowballsEaten has incremented.



Thanks guys and gals

ابتعد عن استعمال المعادلات الرياضية عند استخدام interpolate .
اصنع self.attribute .
ثم ضع فيها المعادلة الرياضية التي تريد .
And Now ::
Make interpolate
Self.size.width TO self.attribute

^^ I'm not good for English..
^^Translate this from arabic Language

Thanks for your response I was able to translate it. For everyone else, so they can know what you said without translating.

@adlaim said "Stay away from the use of mathematical formulas when using interpolate. Create self.attribute. Then place the mathematical equation that you want. And Now :: Make interpolate Self.size.width TO self.attribute"

So, I tried it... and it still isn't working. I set self.barWidth = 10+30*(snowballsEaten/snowballsNeeded)
then I used interpolate self.width to self.barWidth

Still not working... hmmm

I don't know really understand what you want but maby you have to use constrain attribute?

I will take a look at this. Wait.
What´s the issue? Does it not add. Is that what you saying?

Fajlajp

I think I found the issue in your rules just by looking at it. You don´t say when it should interpolate. That´s why it not working I think.
Here is how I would do to say when to interpolate.
Make a new attribute(integer) and call it SnowBallsCurrentEaten(or something)
And then make a rule that says
If attribute game.SnowballsCurrentEaten is not equal to game.SnowballsEaten
Change attribute game.SnowballsEaten to game.SnowballsCurrentEaten
Interpolate self.size.width to 10+30*snowballsEaten.

I did check it out my self and it did work

now I understand what you want xD that should work good thinking @fajlajp

You earn an +1 insightful @Fajlajp Good catch. I made your suggested edit and it worked straightaway.

You know, I did even think of that possibility but I was thinking that um..duh no that isn't necessary because it will always interpolate based on the current value of snowballsEaten... I was wrong but I should have checked it... *shrug*

Thanks for taking the time to reply

The good news is LEVEL 1 COMPLETE! YES!

The following 59 (or so) levels of my game should be faster now!

Great Just send me a pm if you get some more trouble.
