Particle effect to fire just once...

I Have a one shot particle effect that occurs when the player reaches 10 points.

System > Score = 10 > System > Create Object MedalParticles on Layer 50 at (1253, 480)

However the effect continues to loop while the player has 10 points instead of just firing once. I only want the effect to happen once, rather than to continually happen until the player gets 11 points.

How can I get this effect to fire just once?

Either keep track yourself, or use "Trigger Once".

I�ve tried Trigger Once but it didn�t work - I obviously didn�t place it in the correct place. Where in the actions/event flow would it go?

In the properties window on the particle effect there is a property for type.

Just set it to one-shot

Add it to the Score=10 condition, after it.

I currently have:

System > Score = 10 |---> System > Trigger once > System > Create Object MedalParticles on Layer 50 at (1253, 480)

And that still triggers multiple times.

Both conditions should be one event (AND-block, not OR-)
