Eyes are the most important part of human facial expression. Eye movement and blink can deliver a very natural feedback from your character. You can also add some secondary movements to get more natural result. At this example, I've used the Realistic Eye Movements asset from Asset Store to do that. On the example below I've just created a small target and added as a Point Of Interest. Head, eyes and facial movements are all procedural. As this character is from Mixamo, I`ve

With animation Layer we can override or add an entire animation set over other one. You can mask your layer so it only affect part of the body by using an Avatar Mask. At this example, we've create an additive layer for breathing. Stamina is consumed as the player moves. When stamina is low, player's breath is faster then in rest. A script updates stamina value into Animator using based on "Forward" and "Right" parameter. #Unity #Mecanim #Movement #Animation #Animator

Unity's Timeline is a powerful system to create real time cinematics. However, the uses of the Timeline goes much beyond that. Timeline links a scene element to an asset through a Playable Director. You can handle anything that deals with time by implementing as a Playable. You can even mix Playables in a customized way. Notice: - An Animator is required in order to use a Timeline. (Unity ask to add an animator if the object don't have one) - You can create Track Groups to ma

Some people ask me for this example. This is a very very very basic movement system: Just forward-backward and right-left strafe. No rotation included. Steps: .Import animations that actually moves around the space (AKA: root animated). .The tricky part here is to setup the imported content. Check if your root animation is consistent. On my case, all animations have a small rotation over time so I've select "Bake Into Pose" on Root Transform Rotation so they don't rotate anym

I use root motion to move my characters. In that way we avoid the terrible sliding effect that occurs when a character animation don't match a character movement. Sometimes, however, we need to turn it off in order to play animation maintaining our root where it is. There's several cases that this is used. The most usual case scenario is during aerial movements since the trajectory of our character don't change according to his movement (on most cases). However, a third case

Animator recording system is an obscure feature that you find when playing with the Mecanim System. The idea is to create something like a replay. Record and Playback. Simple, easy and... well, not that easy. How to use: Start Record, Stop Record, Start Playback and... nothing work because you really need to manage the playback timeline your own. For that, I`ve created a small piece of code that you can download here. The idea is: - Play using Time.deltatime as parameter. - P

IK (Inverse Kinematic) is an animation technique. Using IK, an animator moves the end-effector bone based in a desired position instead of rotate each bone individually as used on FK (Forward Kinematic). All intermediary bones are dynamically adapted in order to achieve this goal. There's nothing new in IK, actually is an old technique primary used in robotics. In 1998, Jurassic Park: Trespasser, brings IK to Real Time. IK involves some processing power, what explains why thi

I have a very specific way to organize my code. I love to think in architectural terms and my code is always evolving. And that's my current approach: I like to say that my programming is the Unity-way. Not because I like the way the things work at Unity but because I'm working using Unity for a while and coherence is something very important in programming so, for sure, using other Engine, my way to solve the things will probably suffer a huge change. And what is the Unity-w

Not popular as Android, iOS Windows or Linux, Tizen is the next big thing. Probably you never heard about Tizen, but, believe-me when I say that you will. Tizen is an open-source multi-platform SO, but please, don't think about Linux here. There's nothing like Linux on Tizen. Tizen is already used on mobiles, smartwatch and smartTVs but I can assure you that this is only the beginning. Usually, new platforms presents an interesting ROI and this is no different on Tizen. So th

Home Riders was chosen as Game Design of the day on 01/05/2016 by Behance. In order to celebrate this highlight, I'm publishing the Post Mortem from this project below. Post Mortem: Home Riders - Escape From Coliseum By Yves J. Albuquerque The Project Home Riders was the first 3d game for Samsung SmartTV made in Unity. For any experienced developers this first sentence smells like problems but with about 90 days to complete the project this was far from being our primary obst

Unity is really smart in several stuffs. Unity is awesome in choose a good compression format, it works by analising what channels are available and then taking the "most compatible" format for that target platform. Most guys just use the default importing settings and have good results. However, this also can lead to some undesirable result. The surprise comes when someone figure out the huge size of the compiled file some months after the project starts. Sometimes the amon
