We recently invited Code Monkey for his second Dev Takeover on our @unitygames Twitter account. He came ready to answer your burning questions and shared some stellar #unitytips with the community.

If you don’t know @UnityCodeMonkey yet, you might recognize his Twitter avatar of a playful (and surprisingly tech-savvy) animated monkey. As he continues to navigate Unity, he aims to make gamedev easier with a series of best practices and speedy shortcuts. Read our latest roundup of must-try tips on topics ranging from simple Destruction and Minimaps, to the new input system and Screen Space Ambient Occlusion (SSAO).

Take on Destruction in just 90 seconds 💥

If you’re planning to use the Destroy function, look no further:

  • Grab a mesh you want to destroy, then install ProBuilder
  • Go to Edit > Preferences > ProBuilder and enable Experimental Features.
  • From there, go to Tools > ProBuilder > Experimental > Boolean Tool.
  • Duplicate Object and click ProBuilderize.
  • Create Cube and click ProBuilderize.  
  • Drag Object, position Cube, and apply Intersection to cut one piece.
  • If your object starts to disappear, click Center Pivot.
  • Move and scale Cube to cut multiple pieces.  
  • Put all the pieces into one Prefab.
  • Add a Rigidbody and MeshCollider to every piece and toggle Convex.
  • On Bullet Collision, destroy Object, then spawn Pieces Prefab.
  • Bonus: Call Rigidbody.AddExplosionForce();.

Now watch the destruction take place!

Learn the new input system in just 60 seconds 🕑

The new input system might look complex at first, so let’s break it down together:

  • First, go to Package Manager and install the system.
  • From there, create an Input Actions Asset.
  • Define Action Map and set up Type.
  • Define Binding, then listen to Input.
  • Be sure to save the asset.
  • Add a PlayerInput Component.
  • Assign the Input Actions Asset.
  • Select a method (Code Monkey recommends UnityEvents).
  • Put the target function to Action.

You can even check out the Input Debugger for more options.

Smooth things out with Lerp 👈

Snappy movement can look quite janky, but this quick tip should do the trick:

Make a Minimap in under a minute 🗺

Follow these simple steps to make a Minimap:

  • Create a second Camera.
  • Place it above, pointing down.
  • Set it as Orthographic.
  • Create a Render Texture.
  • Assign the Render Texture to Camera Output.
  • Add a Sprite to Player/Objects, pointing up.
  • Assign the Sprite to a Minimap Layer.
  • Change Camera to only render the Minimap Layer.
  • Create Raw Image on UI.
  • Assign Render Texture.

And you’re done!

Enable URP-compatible SSAO to make your game look great ✨

Did you know that the Universal Render Pipeline (URP) has Ambient Occlusion? Use this effect to add in tiny shadows:

  • Select Render Pipeline Asset.
  • Choose the Render.
  • Add Renderer Feature > Screen Space Ambient Occlusion.

Play around with the different values until you get the look you want.
