# SETUP GUIDE ### Animation Event and Event Receiver There are animation events already set up as `On Footstep` and `On Attack` at the monster’s animation files. At the `Animator` object inside a monster prefab, there is a `Animation Event Receiver` script attached to it, which will receive these events and can be used to trigger some functions when the event is fired. For example, in the `PF Skeleton – Archer` prefab, the `On Attack` event is used to trigger the `Launch` function of the `Projectile Launcher` script, so the archer skeleton can actually shoot an arrow. ![](https://442324319-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FmSx8trfX3J4tI1Wvg8rF%2Fuploads%2FHnsxiSWa9YHFibPNvarU%2F0.png?alt=media) ### About Monster Prefabs For every kind of monster, there is only one original prefab, and the skin variations are set up as prefab variant of that original prefab. ### Custom Sort Axis It is recommended that you set `Transparency Sort Mode` to `Custom Axis` and `Transparency Sort Axis` to `[0,0,1]` at the graphics settings. ![](https://442324319-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FmSx8trfX3J4tI1Wvg8rF%2Fuploads%2FIn2nY0U3xG7LnKZ7t9CJ%2F1.png?alt=media) ### Sorting Order Glitch with Multiple Monster You may see some glitch when two monsters are too close. It happens when the two monsters take up the same z space. Give them different z position value will solve the problem. You can set the monster’s z scale to a smaller value like 0.1 (but avoid setting it to 0), so that it takes up less z space. ![When the two monster are too close, and their position.z values are all at \[0.0\].

And in Unity 6.1, the old input manager is no longer the default option. If you encounter any error regarding the input system. Please change the `Active Input Handling` in `Project Settings/Player` to `Both`
