Hello there :) I'm making a 2d platform game with Unity and got stuck with the crouch animation... I have quite a few frames for crouching, so, when player presses appropriate button character sits down and when the button is released I want this animation to be played backward, so, character stands up. Currently in the animator I created two states with the crouching animation assigned to them. Crouch state speed is 1 and so called un-crouch one is -1 which sort of works fine. My inner perfectionist's question: is there more elegant solution for this kind of cases that allows not to "duplicate" states?
Thank you in advance!
Something you can try is to add in your script a parameter to multiply the speed of the animation. You can call this parameters animDirection or something like this.
I am not sure if you want to speed up the animation as well, but just in case you can do something like this:
float animSpeed = 1;
float animDirection = 1;
Now you can manipulate in your script this variables, to make the animation move faster and also forward (animDirection = 1) or backward (animDirection = -1)
gameObject.animation["crouch"].speed = animSpeed * animDirection;
So with this you don't need to have two different states.

Please is it possible to make a Player with rigidbody or character controller run on wall just like The Flash. Please guide me on how to implement this.Here's a link of what I'm talking about. Thank you in advance.
Rotate the player to be vertical to the building, adjust the gravity parameter on your rigid body (make it lower so the added force won't be canceled by it) and just add the force (or set the velocity, whatever makes you happy)
I'm going to assume you already know how to move the player around on the ground. All you need to do is create some form of detection for when they want to begin running on the wall (maybe the player presses a button, or walks up to the wall), at which point you will want to do 2 things: rotate the player to have their feet on the wall, and change gravity to be pulling the player into the wall.
If we assume the player is facing the wall when they go up on it, you can just rotate 90 degrees backwards. Changing gravity should be easy too. Once the player is fully rotated, do something like this
Vector3 newGravityVector = tranform.down.normalized
Physics.gravity = transform.down.normalized * 9.8 //9.8 is the default gravitaty value, feel free to use a different multiplier if you wish.
(this script should be attached to your player)
I would like to understand how to create a script to climb objects of different heights like in this video this.
I know you have to use LayerMask to understand if you are in front of an object, but I don't understand the script that brings the character from below to above the object or on the other side (if it is a wall to climb over) .
For a ladder, I thought I'd put "gravity = false" and "transform.up * Input vertical" to go up or down. But to position yourself above a wall in this way, what script do it's used?
And how does the same animation be usable on walls of different heights as in the video ?
Use an animator, setup your animations in your state machine, in the animator click ‘apply root motion’ and your animation will apply to your character position.
I am wanting to make a birds-eye view pixel-art game.
I currently have two sprite sheets set up, and split and whatnot
groundSheet and characterSheet these are split up into
ground_0_0_0 (A concrete floor)
ground_1_0_0 (grass)
character_0_0_0 (man idle animation frame 1)
character_0_0_1 (man idle animation frame 2)
character_0_1_0 (man run animation frame 1)
character_0_1_1 (man run animation frame 2)
character_1_0_0 (woman idle animation frame 1)
character_1_0_1 (woman idle animation frame 2)
character_1_1_0 (woman run animation frame 1)
character_1_1_1 (woman run animation frame 2)
The numbers after are a note as to:
first number - the main set of sprite animations (eg man)
second number - the animation set in use (eg run or idle)
third number - the frame of said animation.
(the ground has this as i plan to have animated grounds late on)
Now, I wish to make a script for the character (and ground alike) that has an editable value that is view able in the unity editor, for example how things like the sprite renderer has sprite, colour etc. Which dictates what first number to use (see above) what second number and the delay for the animation of the third number. This will then tell the sprite renderer what pictures to load and how quickly to load them. I also wish for the script to scan for the file starting with for example character_0_0_ and then count how many files after it, so it knows what to do when animating. I would like this script to be checking for a change in one of the variables viewable in the unity editor to change and as soon as it does it checks everything it needs for an animtion.
Something else could be done where there is only 1 box to edit in unity, which you put character_0_0_ or ground_1_0_ or something similar, and it checks everything that way (it also makes the script universal, and usable on the ground, character and walls (which I am adding later)).
This may seem confusing, but it make sense for me and many of you will probably mention a much easier way to do animations and such, but please only say these if it does what I want above.
For scripts and such my file layout:
/Assets
/scripts
ground.cs
character.cs
/sprites
characterSheet.png
character_0_0_0
character_0_0_1
character_0_1_0
character_0_1_1
character_1_0_0
character_1_0_1
character_1_1_0
character_1_1_1
groundSheet.png
ground_0_0_0
ground_1_0_0
(For some reason Stack overflow said the above was code, so i had to make it as that)
ground.cs and character.cs are the scripts in which I want to made as explained above.
In my object view thingy I have
Main Camera
ground
character
I am practically a newb to C# and JS I know bascially the grammar of C# (like where to use {} and put ; at the end of the lines). If you help me with this, i request that you explain the script, like use the // thing to simply explain what each command does, I know a few but not all of them. And I know someone is going to say it is really well documented in tutorial X and such, but most tutorials are not in unity 5 and while helping with the matter do not touch on it exactly.
Thank you for your help, if there is anything about this question/request that you do not understand (It is pretty complex) I will explain.
Maybe I am completely wrong, but it seems to me that you are trying to recreate an Animation system.
Is there a specific reason for which you wouldn't use Unity's animation system?
You can do everything that you describe here with it (change sprite, choose animation speed). And you would have almost no code to write. Just drag and drop you sprites in the editor for a start
EDIT - answer to first comment:
What you should do is create all the animations you need. Then in the animator, you choose which condition will trigger a transition to another animation (for instance, boolean jump is true will transition to animation jump). Then in your code you can call GetComponent().SetBool("Jump", true).
To have different character, you can create different gameObjects (one per character). They all have a different animator with animations specific to the character.
The other solutiojn if you really want one one gameObject and one animator is that you also add string condition to you animation (example, if character=="character1" and jump==true, transition to jump animation).
If I were you I would really focus on testing and learning all you can do with Unity animator. I can't think of a case were you would need to recreate the animation system yourself
Your question was long winded and hard to understand but ill try to help,
firstly if you want editable values in the unity editor I would Suggest using a serialized structure of information like this
[System.Serializable] // this makes it viewable in the inspector
public struct Sprite_Manager;
{
public Sprite[] Render_Sprites; // array of sprites to store sprites
public SpriteRenderer S_Renderer;
public float Anim_Delay;
}
public class Character : MonoBehavior {
Sprite_Manager SMG = new Sprite_Manager(); // instantiate a new instance of the struct
void Set_Sprite()
{
for(int i = 0; i < SMG.Render_Sprites.Length; i++)
{
SMG.S_Renderer.sprite = SMG.Render_Sprites[i];
}
}
void Update
{
Invoke("Set_Sprite", SMG.Anim_Delay);
}
}
Not sure if this is exactly what your looking for but this is one way you could setup a structure of sprite based information and use Invoke to setup some sort of delay when passing new sprites to the renderer.
I have a marine model used in my start project, which will uncontrollably lift off the ground when running. I import the fbx resources, set the animation type as humanoid and configured the avatar by automatically mapping, set up a animator controller that contains only a running animation. Here is about several seconds after playing:
But when using a generic animation type everything works fine. Any suggestions to fix this while still using the avatar system?
UPDATE：
Configure of my 3D model:
This is obviously caused by root motion. What happens is, one loop of your animation takes the character slightly higher. Adding these slight changes up, you get what you're getting. If you don't need root motion (doesn't look like you do), disable it (from the animator component's settings). If you do, either edit the animation to make sure it fits, or disable root motion along the Y-axis (you can do this from the animation's import settings).
In case you don't know what root motion is, it's when the root bone of your model has animations applied. You obviously can't create the entire animation of character running up and down your levels, and until recently (though not MUCH recently) characters where animated in-place, and moved procedurally via code (I know for a fact that Unreal Tournament 3 uses this method, as would any UDK user). Then, people started wondering how they could make their characters move more realistically? I mean, it's not like you walk forward at a constant rate of 4 km/h, you tend to slow down and speed up during different parts of the walk cycle. The same can be applied to video game characters using the technique known as root motion.
With root motion, you actually move the character forward during its animations. This will cause an animation to look really bad in max or maya, since the character will just snap back to its original place after a loop. However, this data is used intelligently in game engines: Rather than use the absolute position the animation yields, you take the velocity out of it between each two frames, and move your character based on that velocity (Unreal engine actually has a really neat acceleration mode for applying root motion, though I'm not really sure how that would be different from velocity mode). This will make your character move forward at the same rate the animation does, and thus you can actually animate the character's movement as well as its limbs and joints. Moreover, since you're using the velocity and not position data from the animation, it will look exactly as you'd expect it to. If you're interested in this technique, take a look at the Mechanim demo pack they have on the asset store. It makes extensive use of root motion to move the character around.
My company was having a similar issue but we still wanted to keep the "Apply Root Motion" toggle checked. When the same animation played on loop, the model stayed in place but if several different animations were played one after another, this caused the model to rotate / shift in position.
The solution for us was ticking these check boxes in the animation settings for each animation. Root Transform Rotation, Root Transform Position (Y), Root Transform Position (XZ).
I had the same issue a few days ago. I found out that the problem was the Apply Root Motion in the Animator script. Make sure it's unchecked.
Tag your player with "Player" in scene
and use this script
float y;
GameObject player;
void Start ()
{
player = GameObject.FindGameObjectWithTag("Player");
y = player.transform.position.y;
}
// Update is called once per frame
void Update ()
{
float diff = player.transform.position.y;
player.transform.Translate ( 0, 0,z - diff);
y = player.transform.position.y;
}
it is little hacky soultion but works!!
note: if you want to use y movement at some point just calculate and add it to diff variable.
For those who couldn't solve this issue with 'bake into pose'.
I tried 'Bake into Pose-Y', but it didn't work.
Meanwhile, in FBX > Animation > Motion, I set 'Root Motion Node' as 'Root Transform'(It was 'None' before), it solved my problem. Unity version is 2020.3.34f1.
I'm making a side-scrolling Mega Man based game in C#. I am NOT using the XNA frame work to do so. I'm looking at creating multiple "bullets" from one location using one single image within my game class. The only thing I can think of at this point is something similar to this:
if (shooting == true)
{
BulletLocation.X += 3.0F;
Bullet = Properties.Resources.Bullet;
Charecter = Properties.Resources.shooting;
}
Shooting is set true on the keyDown event, and set to false on the keyUp event. I'm positive i would need an array of the sorts, but I'm not sure exactly how I should go about it. Thanks for your help!
EDIT:
What portion of that code would actually allow you to generate multiple "bullets" from one sprite single sprite? When the user presses the space bar, I would like to create a bullet that moves forward until it reaches the end of the screen. I can do that part easily. I cannot, however, do it with multiple bullets. I can only have one bullet alive at a time. I'm not sure how I would go about creating multiple bullets on the forum from one single image.
If I understand it correctly, you want to show multiple bullets, right?
I would make a variable for # of bullets and bulletposition.
So lets say:
const DISTBETWEENBULLETS = 3.0;
int distToOpponent = 9.0:
int curBulletDist = 0;
do{
curBulletDist += DISTBETWEENBULLETS;
//Draw bullet
}while(distToOpponent <= curBulletDist);
I hope this helps, and if it doesn't answer your question, or you mean something else, feel free to ask.
