Adding +1 to Score Only Once

HolyHippo

I'm working on a game where you tap a particular object to score a point. After its tapped I want it to continue across the screen. Right now I have it set to...when pressed game.score+1. That however allows the player to continuously tap the object to increase the score.

How do make it so tapping each object only increases the score by 1?

Thanks!

make a self attribute called tap in the object and set it to 0

then have a rule in the object when attribute tap=0 and touch is pressed
-change score to score+1
-change attribute tap to 1

I think I understand that. I'm trying it and I'm obviously doing something wrong.

Here's what I did...

1. Rule...when pressed change score to score+1
2. A Rule under that ...when tap=0 change tap to 1

On the actor that is tapped to add +1 to the score, create a self.attribute that's an integer and call it self.score.

In that same actor, create a rule that says this;

When self.score = 0
AND
touch is pressed

Change attribute self.score to 1
Change attribute game.score to game.score + 1

That will only allow the player to add +1 to the score ONLY one time.

(Only need one rule. You don't need a rule imbedded in the first rule).

You guys rock. Got it to work.

One thing I forgot to mention. I'm having the same 4 objects repeatedly spawn on one side and scroll to the other. So having this set up now I tap the one object and the score increases by 1 but when I tap on the next spawn of the object nothing happens because of the constraint I've put on it.

Hi HolyHippo, one way around your problem is to make duplicate actors in the inspector, so that you can use different attributes for each: make 4 attributes, game.scoreA, game.scoreB, game.score.C and game.scoreD. So replacing these in DrGlicket's Rules you'll have control of each one.

Also guys why not use Boolean? I remember that I post a thread about that

Bool is faster then int

HolyHippo

Ok...I think I got that. I'll try it out.

Thanks!

HolyHippo

Ok...I tried that and I'm doing something wrong. Any other ideas? Or should I keep trying?

Appreciate the help!

I'm a big fan of Boolean - I find it makes things easier to understand and remember, which then leads to fewer mistakes.

I didn't know that it's faster than using integers - that's an added bonus!

This is how I would have done it - the key is using SELF attributes and not GLOBAL ones. This way, changes should affect only one instance of an actor rather than all of them.

Can you confirm you are using self attributes?

HolyHippo

That was the problem. Thanks DrGlickert and Octappus!

Now I have a wall set up at the end that if the actor touches it it subtracts a life. How do I make the wall only subtract a life if the actor hasn't been tapped? In other words whether or not the actor has been tapped a life is subtracted when it hits the wall.

Octappus

Use a rule, for example:

When ... actor receives event ... overlaps or collides ... with ... actor of type ... wall

If you don't refer to the self.score attribute, then it won't matter if the actor has been tapped or not.
