How to trigger a rule only once?

stefdelec

Hi,

I am making a gameword, and I want the letter to spawn according to the letter around. One letter per actor. So I made several rules. But letter are keeping changing after the first time they spawn/appear. How can I be sure that when a letter spawn and a letter is assigned to an actor, it doesn't change afterward.

I think there is something I have not understood with rule and change behavior.
For example:

If x= 0 => change attribute to true,
otherwise change attribute to false.

Let say during the game for a reason, x is changing to another number than 0, it will trigger "otherwise". Am I right?

Basically, I want the rule to be triggered only once, when it appears. And that all. Should I put a boolean "rule triggered"?

Yes just create a self attribute and use it as a lockout.

Tks.

I have done it, and I don't understand at all but it keeps not working.

I have included a boolean.
If letter assigned false=> trigger rule.
[
Inside the rule, I said if parameter 1 =>assign a letter And change attribute boolean letter assigned/
otherwise 'rule if parameter 2'=> assign a letter And change attribute boolean letter assigned/
otherwise assign a letter And change attribute boolean letter assigned.
]
(assign a letter in 3 different manners).

So it shouldn't be changing again or do I have a logic error.

I'm confused what rule do you only want to fire once. The main rule or the rule in the otherwise section?

stefdelec

Any of these which assign a letter.

When letter is assigned, don't change it! :-)

The 3 parameters:

• If there is too many voyels,
• if there is too many consomne
• None of the above.

According to these 3 parameters, it assign a letter to the actor, and it doesn't change even if "voyels" consomne"...etc changes.

That doesn't help me as I don't know your code or overall game logic. Post a screen shot of the code your talking about.

Here is how I would do it. Create a self attribute in the actor or actors call it lockout.

Rule

If all

Condition you have that fires the rule. Self.lockout is false

Behaviors that are in the rule.
Change attribute self.false to true

Otherwise

Rule

If all

Self.lockout is false

All the code you have in otherwise inside this rule.

I m not sure it gonna help.... :-)
I am sending a new screenshot as this one is not good.

Yes, it is what I have done, (I think) but it is keeping changing.

The_Gamesalad_Guru

I would abandon the idea of using otherwise and do it all as straight conditional logic.

stefdelec

Ok. I ll do.

The_Gamesalad_Guru

Using otherwise can be tricky. Your logic will be easier to control without the otherwise kicking in.
