    Hello everyone! I just released part 2 of this video! It’s an independent animation scripting system that works with layers and animation locking (and is very easy to use). Go check it out!

    It's actually pretty smart but also simple. I mean, even if you use the animator transitions and variables, you need to change them by script, so why not do all the rest too? You opened my eyes, thank you!

    This has some drawbacks though. Consider large game with large codebase with lot of legacy code, or case when you even don't have access to some code. Then you are porting some features and in that case using animator is really convenient. Otherwise your visuals are tightly bound to code, which is not good. Or you can't give some tasks to tech / ui artists who are not that familiar with code.

The hierarchy for my player is "Player > Player Model", my player controller script is attached to the Player game object and the animator component is attached to the Player Model game object.

    • @SmallHedgeHQ
      @SmallHedgeHQ  7 місяців тому

      Hmm bizarre! I’ll try to troubleshoot everything that comes to mind.
      1. When calling Animator.Play(“”), the string needs to be exactly the same as the Animator state name (not the animation clip name)
      2. It needs to be on the right animation layer (default is 0)
      3. The Animator itself has no transition lines
      4. Ensure that GetComponentInChildren() is getting the right animator component (print animator.GetInstanceId() and go to the inspector and enter debug mode in the top right, make sure they match. Or just call animator.name)
      5. After animator.Crossfade() (with crossfade = 0) print animator.Update() then animator.GetCurrentAnimatorStateInfo.IsName() then test if it is actually playing the animation
      6. Check if the animator component has a valid animator controller
      Hope that helps! If not, flick through the code and we might be able to spot something.

    Hello there, I wanted to organize my Animations with state machines.
    Now the Animation won't switch anymore.
    I think it's because it's not in the "area" anymore.
    Does anyone know if it's possible to switch between state machines and how?
    Thank you for any answers!
    Edit:
    I'm able to access the AnimatorController and through that the Base Layer as an AnimatorStateMachine.
    How could I switch the StateMachine...?

    for the idle animation, wouldn't it just be easy to set the first value of currentIdle to 1, check if it's over 7 and loop it back to 1 and just have the last else call ChangeAnimation($"Idle {currentIdle}"); ??? Just kinda feels like there's no reason to add extra steps for something relatively simple.

    • @SmallHedgeHQ
      @SmallHedgeHQ  8 місяців тому +1

      ​@@maxgordon3194 Right. There are two ways this can be approached: Using one animation controller and using many animation controllers.
      Setup:
      Have an animator component attached to the player. Put every weapon as a child of the player in the appropiate rigging position and disable all of them. The animation controllers have two layers: Upper Body and Lower Body.
      One Animation Controller:
      The Upper Body layer is where you place every single player movement animation (idle, move, jump etc) and every single weapon animation ever (hammer idle, hammer swing, shotgun idle, shotgun shoot etc). The Lower Body layer is where you put all player movement animations that use the legs. Use the AnimatorBrain script as in the mentioned video. To disable/enable weapons when you switch you can either: enable/disable in the animations themselves (at the end of the put away animation it disables it and at the start of the pull out animation enables it as a keyframe) or enable/disable them in script.
      Many Animation Controllers
      Have an animation controller for each weapon. The Upper Body layer for each animation controller contains exactly the same as ^ except it only contains animations for the current weapon. Then when you come to switch weapons, disable the current weapon and enable the next weapon (as described in ^) and swap the animation controller in the animator to applicable animation controller. Great thing is you can make each animation controller visually identical (same state names so Animation.Crossfade() will work) but the states hold the applicable weapon animation.
      For using One Animation Controller its advantage is Animation.Crossfade() works when swapping weapons. The advantage to Many Animation Controllers is adding more weapons can be done at runtime procedurally and is easier to handle as the project scales but beware, making a change would mean making that same change in every animation controller.
