How to make actor spawn only once?

justinodunn

i made it so if the user touches the screen an actor will spawn and appear for a few seconds and be destroyed when the timer is up. But when i touch the screen again, the actor will spawn again... so how can i make it spawn only once after the screen is touched once?

Armelline

There are a number of ways of doing this. Which is best will really depend on how you're handling the touch of the screen. Probably the easiest and safest way though is to have an attribute (boolean or integer) that you toggle when the actor is spawned.

Rule: When attribute TOGGLE is 0 then
Spawn Actor
Change attribute TOGGLE to 1

That way, it'll only spawn the actor when TOGGLE is 0, and as soon as the actor is spawned, it'll change toggle to 1, preventing any further spawning.

Socks

Make boolean attribute.

Touch changes it to true.

When true spawn actor.

I think this thread may demonstrate that Socks is an optimist and I'm a pessimist.

Nevermind, got it! Thank you guys! It's good to sometimes be pessimistic and sometimes optimistic

We came up with essentially the same solution at the same time, but yours relied on something being true and mine relied on something being false :P

@justinodunn Can you please share with me how you did it? I am killing my self over here trying to make it work but nothing. I tried @Socks and @Armelline methods but it seems i am making mistake somewhere but i don't know where!

@RedCubeGames You might want to post a screenshot of your rules so we can help you (upload the screenshot to a file-sharing site and then embed/post the link here). Based on what @Armelline wrote, the rule should be:

When Mouse Button is Down
     When Attribute self.toggle (integer or boolean) is 0
          Spawn Actor [actor name]
          Change Attribute self.toggle to 1
