The first area focuses on selecting sounds and playback.
You can use the left and right arrows to navigate the SFX IDs or enter an ID by hand to load a sound effect. Each sound can have a label that is there to help make organizing sound effects easier in the tool. The engine does not use the label; sound effects are only accessible by their ID in code.
You can control a sound’s playback to the left of the SFX Name field.
Here you can play the currently loaded sound effect.
