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.

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)
Lets say I have a path, could be a line or a curve in Unity and I wanted to allow my player to snap to that path and move along it how would I achieve this. This would look like either a cover system or something similar to how ledges work in Sly Cooper.
While if you want your player's movement to follow a path, there is a technique called WayPoint, which is simply using the build-in navigation system in Unity. There exist so many articles that teaching you how to manually build such a Way Point System, and at the same time, you can get a SimpleWayPoint module from the online assets store.
But if your player is controlled by user, which means the user can control it's movement, let's say pressing 'W' button meaning moving forward while pressing 'S' button meaning moving backwards, and the leftwards and rightwards movement are constrained by the path you defined, unfortunately I didn't find any mature technology which allows you realize this constrains.
However, in the project I accomplished several months ago, I manually handle the coordinates successfully, since I create a city whose streets strictly observe horizontal and vertical grid lines, I can easily controls the target gameobject's X and Y coordinates, by either using the build-in freeze coordinates API or manually reseting the axis values over and over again in the Update() method. So maybe you could using the Update() method to constrain the targets' coordinates by dynamically calculating it's coordinates using the functions representing the path, but I can imagine how complex it would be.
You could try using a navmeshagent, which will be enabled as soon the player would like to use this "auto movement". In your code you can set the destination and in your scene you can create a navmesh, which can be whatever shape you like
You can do it by:
Mark the position from where you want your player NOT to move forward/cross the line.
In your script, mention the position.
LOGIC
if, player position > position marked
then stop the movement,
SYNTAX
private void update(){
if(transform.position.x < -10){
transform.position = new Vector3(-10, transform.position.y, transform.position.z); // Here you can either use `Vector3` or `Vector2` according to your game
}
}
I am currently making a sidescrolling game in Unity 2D where an enemy rises up, and then dives down to the player, but then keeps going until it is off screen, like how this image shows. 1 I can get the enemy to collide with the player but I can't make it keeping in that direction until off screen. How would I be able to do this?
You have to make your collider to trigger (it's a checkbox on your collider)
That means your object will not be affected by physics when it touch another collider, but it can calls functions.
You have to replace OnCollisionEnter/OnCollisionEnter2D, etc by OnTriggerEnter/OnTriggerEnter2D, etc.
Be careful, the parameter of the function may change too (Collision/Collider).
I downloaded 2 animations from Mixamo called Idle and Walk_Forward. I created my controller with blend tree and it worked fine. But the problem is when I press W button, the character only move a short distance then back up to the orginal place where he start "Idle". Someone told me to download animation with "In place" option. So I tried then had another problem: The character just play animation but not move forward. About my component on character, I created RigidBody with Use Gravity, and the animation and character is humanoid type. How can I make those animations work ?
If you are using an animation which animates in place then you'll have to add a characterController to make you're character actually move. The animation will only make it look like you'r player is moving. Here is an example of how to move your character.
Implement import of model settings and set "Animation Type as humanoid" in the Rig tab. Then press Apply. Now your animation would not repeat.
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.
