Play sound when object falling down

this nodes don’t play sound.

i tried with mouse left click and there is no problem with sound. i can hear. but with this nodes i can’t hear any sound.

where is the mistake?

Hi, a general rule of thumb in Armory is to match the logic node socket colours.

In your logic node setup, the result of the math node is connected to the post sound node. The play sound node needs an action input (red socket, kind of like a “trigger”).

So, try replacing the math node with a gate node to check if the value is less than certain other value at every on update.
