6. Add Wave

Until now it was placed directly in the scene for confirmation, but in actual games it is almost always to appear from the middle.

Finally, I will incorporate it into Wave and let Enemy 3 appear.

Previous tutorial

Apply Enemy3 to Prefab

We will apply the edits so far to prefab.

Please select Enemy3 and press Apply button of Inspector.


Duplicate Wave Prefab

Duplicate Assets/ShootingGame/Prefabs/Wave prefab  and change the name to Wave2.


Place Wave2 in the scene

For editing, place Wave2 prefab in the scene.


Instantiation of Enemy3

Change it to instantiate Enemy3 from Wave2.

Please open ArborFSM of Wave2 in Arbor Editor.

Set Wave.

Spawners / Size 1
Spawners / Element 0 / Prefab Enemy3 prefab
Spawners / Element 0 / Transform Pos3 object
(In the center this object)

Apply Wave2 to Prefab

Press the Apply button on the inspector of the Wave2 object to apply it.


Delete Enemy3 and Wave2 objects

Since you no longer need to edit it, delete the Enemy3 and Wave2 objects.


Wave 2 starts after Wave 1 ends

Please select Emitter object from Hierarchy.

If Emitter was disabled for play confirmation, enable it.

Open ArborFSM in Arbor Editor.

It duplicates the Wave1 state and renames it to Wave2.


Change InstantiateGameObject of Wave 2.

Prefab Wave2 prefab

Rename original Wave2 state to End Wave.

Set to transition from Wave1 state to Wave2 state and Wave 2 state to End Wave state.

This Wave was able to add.

Play Check

Finally press “play button” to check the operation.

When Wave1 ends, you can see that the created Wave2 starts.
