[Unity/Playmaker] Make a slow-motion function. Make a bullet move.

This article will show you how to make slow motion in Styly’s VR space using Unity’s Playmaker. This is done with the clicksand the HTC Vive’s controller.

This is what the finished image looks like. Time goes into slow motion only when the trigger is pressed.

Sample

You can experience the sample space from STYLY GALLERY.

You can also download the Unity project introduced in the Slowmotion_Sample article here. Slowmotion_Sample project data does not include any plug-ins, so please install them yourself before using them. Playmaker SteamVR Plugin

Playmaker and Steam VR Plugin

Download each one from the asset store and make it ready to use in Unity.

Playmaker is a paid asset. Playmaker

Steam VR is free.

Creating a Bullet

Create a bullet as a moving asset to expericen the slow motion.

I changed the name of Sphere to “Bullet” and set the scale to 0.1 for each. Select “Bullet” and open the Playmaker Editor.

Right click and choose “Add FSM”.

A new State has been created. Changed the name of FSM to Bulletspeed. Next, add an Action to the Bullet.

Click on Action Browser

Select Transform Translate from the Browser and click Add Action To State. Action has now been added. Set the speed of the bullet.

I set Z to 7 in this example.  

Make it a Prefab.

Set a spawn point for the bullet

Make a cube with the name, “Bulletspawn”. Uncheck the box of Mesh Renderer.

  I also add an FSM to the Bulletspwan by Playmaker.

Add “Find Game Object” by “Add Action”.  

Select “Main Camera” from “With Tag” to find the objects with the tag, “MainCamera”.  

Create a new variable by “New Variable” and store it to the found object.  

In this case, I named the variable mainCamera. Add State to create a new State.

  Add an action, “Look At” in “Transform” section.

Add a Look At from Transform

Selecting a Target Object

Set the Look At target to the MainCamera we just created and uncheck Keep Vertical. Set the Transition of State1 to FINISHED.

From there, we will connect to State2.

Next, create a State3 and add a Create Object action.

Specify the object to create.

Specify “Bullet” for Game Object and “Bulletspawn” for Spawn Point.

Add a Send Event Action and set the Transition to FINISHED. Connect State2 to State3.

Connect State 3 to State 2 as well, as it is repetitive.

Add Wait so that it fires every second.

The time was set to one second. The Finish Event is set to FINISHED. If this is the case, bullets will continue to fly, so I’m going to Destroy at the appropriate place.

Changed the delay time to 4 seconds by specifying a bullet in Destroy Object. In this article, I showed you how to generate bullets automatically using Unity’s Playmaker. In the next article, I am going to show you how to make this bullet move in slow motion. Continue reading How to create a slow-motion scene in Unity’s Playmaker_vol.2
