For some days I was thinking why my animator looks messy now I got it how to make it look clean thanks code monkey ☺️👍

@yesyoutooo8842 4 года назад

Thanks for all the tutorials! You could make another blend tree video where you show how you can use blend trees to play the right animation based on your current mouse position. So if your cursor is to the top right of you and you press the attack button you play the attack top right anim. Surely would help a lot of people doinf 2d top down! I had a lot of trouble getting that work for the first time.

@CodeMonkeyUnity 4 года назад

The logic for the animator is the same, the animator doesn't care where the horizontalMovement and verticalMovement parameters came from. If you use the direction vector towards the mouse instead of the movement vector, everything will work the same. I covered a mouse based combat system like that here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-AXkaqW3E9OI.html

I'm trying to build a more code oriented animator to avoid a transition hell, do you think blend trees are a better approach than force Play a state through code? As always, thanks for the top notch content

@CodeMonkeyUnity 4 года назад

Blend trees really help cut down the number of transitions required so they should help you avoid transition hell. Also you can put blend trees inside blend trees. By doing Play() through code it seems like it will end up just as messy but keep the mess in the code instead of the animator. It's always tricky to handle tons of animations so try many things until you find the best approach for your case!

I have a sword slash animation. It just rotates the sword with a bit of positioning. When I drag the mouse over the frames slowly all is good, but when I hit play it skips random frames in the middle of the animation. Looks terrible when using it with a trail renderer. Any ideas why?

@WorldEnder 4 года назад

hey there, @codemonkey! I'm currently trying to watch your vids about mesh animations and your guest spritesheets but somewhere down the line (after you show how to draw the uvs and how to create a random guest), I get lost, I cannot find the how to animate video (it seems only part one of 2 is available) :). If noone can point to that video on your playlist, will you show us how you create the sprite animations you mentioned in this video? maybe in your future course, cheers !

@CodeMonkeyUnity 4 года назад

For making sprite based animations you just draw the sprites and then in Unity you slice the spritesheet. I'm not good at drawing so I don't have any drawing tutorials but there's tons on RU-vid. Drawing for games and drawing for anything else is the same.

@isaiahwilliams1520 Год назад

How come you attached the Animator component to the parent obj but it still affects animations for child obj (sprite)? mine isn’t behaving the same way. I’m trying to apply this method in a 3D project if that clears anything up.

@isaiahwilliams1520 Год назад

My sprite renderer component is attached to my child object (sprite) and my animator component is attached to the parent object.

@cybertech1076 Год назад

This works if I only wanted to animate the gun in the hand of a first-person player when they move with the gun right?

Sure, you can blend any animations you want, so you could have animations for the gun swaying in different directions

Hello Mr Code Monkey! Am loving your videos very much. I have always found them to be extremely helpful. Would you consider making a video regarding Unity's Animation C# Jobs system?

@CodeMonkeyUnity 4 года назад

@@CodeMonkeyUnity Ahh yes! I actually learnt how to do DOTS stuffs by watching only your videos and nothing else! Your videos made the entire learning process easy and painless. Unity did release an animation C# Jobs system (blogs.unity3d.com/2018/08/27/animation-c-jobs/), but alas, there appears to be not much tutorials about this on youtube. Alright! Will be looking forward to your videos as usual! Cheers.

@jeromej.1992 4 года назад

Is it intentional that u never set the horizontal/vertical animator parameter to 0 so the idle position matches the last direction? Or would Unity remember the last one active if values are all 0.

@CodeMonkeyUnity 4 года назад

The parameters are only set when the character is moving so when the character stops moving the parameters keep their state for the last move direction

@YoonutzBv Год назад

Can you recommend me a way to help me work with Blend trees and animation swap? I am struggling to find a tutorial for my frame by frame animation game sprite sheet animations. Everything that I have seen so far, don't work with Blend trees

@CodeMonkeyUnity Год назад

You can't blend sprite sheet animation, you can't automagically blend 2 sprites together, so you can only use blend trees to do what I'm doing here, define the animations and instantly change between them without any blend.

@YoonutzBv Год назад

Thank you for the replay. I have one last question, for your character animation movements. Did you used any Animation Clips or everything is done in code in any of your videos? Because I do not recall seeing any video from you where made the animation movements for all of the directions, for your characters. Would you mind pointing if out, if it is one available ?

@bobmcbob4399 3 года назад

for isIdle comparing float variable with exact zero is a no-no. You should reform the state check to use > and a very small number close to zero like 0.1f . This would be: isIdle = (moveX < 0.1f) && (moveX > -0.1f) && (moveY < 0.1f) && (moveY > -0.1f)

@CodeMonkeyUnity 3 года назад

The value comes straight from the input, there's no math applied to it so you can safely compare directly with 0. floats only become inaccurate when you start doing math

@bobmcbob4399 3 года назад

@@CodeMonkeyUnity ok cool, thanks for the replies

@davef101 4 года назад

Always use Animator.StringToHash. eg. animator.SetFloat( Animator.StringToHash( "horizontalMovement" ), moveDir.x ); Or define the Animator.StringToHash( "horizontalMovement" ) as a const int. This is a way faster operation.

@CodeMonkeyUnity 4 года назад

Sure, if speed is a concern you can make it faster. But don't bother with overengineering if it's not necessary.

@davef101 4 года назад

@@CodeMonkeyUnity Sure, that's a fair comment. But, coding practices like these are highlighted to our Junior Devs as soon as they arrive at our studio and I think it's a good discipline to have. When working on large scale projects, things like this add up.

I reckon not everyone can afford ReSharper, but if you do and install the ReSharper for Unity's extension, it suggests to do the modification for you automatically. I've personally never been taught it but if ReSharper suggests it to me, I don't need to remember it.

Why did you use Update() for Rigidbody.velocity() vs FixedUpdate()&

@CodeMonkeyUnity 4 года назад

Setting the rigidbody.velocity doesn't directly move the Rigidbody, it just sets the velocity and then on the next FixedUpdate() the Physics system applies that velocity.

@denisgoodman4492 4 года назад

@@CodeMonkeyUnity Can be it spread more widely - if we change properties of Rigidbody - it can be did in Update() (or must be made in Update())? And if we use some methods Rigidbody it must be did in FixedUpdate()? Always?

@bobmcbob4399 3 года назад

Why not add a multiplication (for each case in X and in Y direction) with Time.Delta to make your movement code frame rate independent also?

@CodeMonkeyUnity 3 года назад

The movement is handled by the rigidbody velocity which already handles deltaTime

The blend tree helps you easily manage complex animations, like managing left-right-up-down animations If you've ever tried manually doing your own state machine to manage left-right-up-down animations you would see just how complex it actually is and just how much simpler the blend tree makes it.
