Unity bounce on collision 2d no bounce or walking through it. Sep 11, 2020 · Hello i’m trying to create a ping pong version where the player moves around a circle and plays ping pong with oneself but i’m having a hard time coding the ball to bounce off on collision with the player. It seems that often when the ball bounces to a brick, it will bounce the opposite site again (see red line, while the ball still should be going upwards) Below info about how it’s been setup Bricks have a boxCollider2d bounce material (no fraction) important : there are no gaps between those bricks Ball have a boxCollider2d (also tried As pat mentioned you will need to make the wall and the ball a 2D collider and do this reflection in the OnTriggerEnter2D method. Now i want to introduce collisions and physics to my game but after attaching the rigidbody component and moving around i realise my movement has become very clumsy and well - not nice - to look at Select the Physics Material 2D Use to adjust the friction and bounce that occurs between 2D physics objects when they collide More info See in Glossary that determines properties of collisions, such as friction and bounce. contacts[0] - ballPosition. Now, when the sprite Nov 14, 2023 · I am making a 2D game where balls bounce from the edges of the screen, However, there seem to be two types of issues with this kind of bounce method, and every tutorial I checked uses the same method. More info See in Glossary asset’s Bounce property has a value of 0–1, which represents the coefficient of restitution. However, with a velocity vector above (0. On the fixed update the “bounce” will be “overridden” by the code in your fixed update - since you are directly assigning a position to the rigidbody. Apparently the object goes inside the wall’s boxcollider and return to the previous position generating thus that orrible shake i’m trying to fix. Collections. when it collide with the wall it bounce off this might help to understand. The normal of the collision will be defined as the direction from the ball center to the collision point. I’m actually using the 2D setup , trying to make a RPG game FFV like. The effect is basically a vibration between the two Apr 16, 2011 · As I wrote in comment Bounciness 0 still bouncing - Unity Answers and as discussed here Physics objects bouncing when bounce is 0!! - Unity Answers It may be an objects penetration problem. In that case you could let the bounce happen and then use AddForce in the direction of the ball's velocity right after bouncing. i tried that with Raycast but i guess it’s slower than the player impact speed. Aug 15, 2016 · So im quite new to unity and ive decided to start working on a 2d rpg, using sources from this site ive manged to get a code that gives me grid movement much like that in the older pokemon games. Jul 7, 2020 · First: I don’t see any code here for any bouncing. Jun 28, 2022 · I am making a game in 2D where you need to avoid hitting shrapnel. Jul 4, 2021 · Hello! as the title states, objects seem to “Bounce” slightly when hitting collision with some velocity. Even though these issues happen rarely in the game, I created the exact moment they happen, you can see both issues in the video. Every time that the player walks and join a collision with the cube it bounces back if the cube doesn’t have space to move in the direction that is being pushed Here is a video showing the bouncing 2020 05 03 02 38 22 - YouTube (when i go back im May 4, 2011 · If you set Object2 to kinematic, Object1is not kinematic. I got the explosion and shrapnel ready, now i just have to destroy it when hitting the player for example. If you want it to bounce you have to write the physics code to detect a collision and change the movement or you can do addforce to move the object and it will detect collisions and react automatically. Nov 26, 2013 · Hi everyone, i just started my experience with unity a few days ago and i got stuck with this problem that probably for the most of you is a stupid issue. This is all handled by Unity's PhysicsEngine itself so you don't have to worry about that. i’m searching for a way to stop the rigidbody when it reach a wall. Any help is appreciated. g6fj4u issue; sometimes, the objects do not recognize the Jun 3, 2017 · Add a tag to the Edge Collider game object, write a script to detect collision and check for this tag, then have 2 Boolean variables (e. velocity to zero on collision. You can use Vector3. You can try setting rigidbody. When Object1 collides to Object2, Object2 doesn’t move, doesn’t rotate but what I want here is Object1. Dec 7, 2016 · I have visited many tutorials and seen many resolved questions, but none answer my question, I want the player to bounce off an explosion in the opposite direction it collided with it: Graphic Representation The explosion is not always there, it happens when the player touches that exploding apparatus, then the exploding apparatus spawns an explosion prefab, that works perfecltly fine, but the Nov 30, 2017 · So I have a player that bounces a little when colliding with an object. A possible solution would be using ray In PhysX, the Physic Material asset’s Bounce property has a value of 0–1, which represents the coefficient of restitution. i want the player to just stop moving when it reach a wall. Is Trigger: Enable this if you want this Collider 2D to behave as a trigger. 26, 1), it sticks to the wall. What do you think is this possible? On each frame, Unity checks the cache for a plane at the position of the particle, and if there is one, Unity uses it for collision detection An automatic process performed by Unity which determines whether a moving GameObject with a Rigidbody and collider component has come into contact with any other colliders. Jan 28, 2023 · i want to make an object not really bounce but in fact more like go in the opposite direction with the same velocity. Trigger collider works better in my experience Sep 25, 2017 · Hi, I’m using unity2D for creating a breakout game. using System. Unity's physics not working well on high speed collisions. It works fine with static objects, however it doesn't keep the same velocity with moving objects : the bullet can push things, but will slow and I don't know how to remove the slow. So, to conclude everything in one post: To disable bouncing you use the PhysicMaterial, set bounciness to 0 and you may need a bounce combine set to minimum. My player is rigidbody Apr 16, 2014 · So I basically have two gameobject with a boxcollider2D attached to it, one is a static wall without rigidbody and the other is let’s say the player that I scripted to move using transform. Once that is working, bisect back to what you have and find what part Jun 3, 2017 · Add a tag to the Edge Collider game object, write a script to detect collision and check for this tag, then have 2 Boolean variables (e. Because Object1 sometimes pass through Object2, sometimes bounce and move forever after collision but I want it STOP, not bounce, not pass through Object2. Create a new physics material 2D in the assets, set its Bounciness to 1 and Friction to 0, then drag it to the Material of the ball's Rigidbody 2D component. If you move the object with transform. Nov 17, 2024 · Collisions in 2D definitely work. It’s not even visible to the eye but it’s messing up my camera so it needs to go. If you attached a physics material to the player and are relying on it to provide the bounce- that’s your problem. 26, 1 . I have Box colliders on my character and walls/floors. Those bullets have infinite bounces and keep the same velocity after bouncing. Or you can use trigger collider to detec collision and then set the velocity to zero. Somethign like; N = collider. Apr 16, 2014 · So I basically have two gameobject with a boxcollider2D attached to it, one is a static wall without rigidbody and the other is let’s say the player that I scripted to move using transform. position what you are doing is basically a "teleport" so it will ignore the bouncing material. May 13, 2017 · 1) You haven't assigned a physics material to your ball. Generic; using UnityEngine; public class ballmove : MonoBehaviour { private Rigidbody rb; // Start is called before the first frame update void Start() { rb = GetComponent<Rigidbody>(); } // Update is called once per frame void Jan 4, 2019 · bounciness 1 means that on collision the object won't loose any speed but instead bounce back with 100% of its velocity at the according angle. I’ve created a Sprite object for the main character,with a 2D Box Collider and rigidbody (setting gravity scale to 0, so it doesn’t fall down). Jan 30, 2018 · So I am trying to set up a simple 2D platformer. Jan 23, 2024 · [SOLVED!] I’m encountering an issue in my Unity 2D game where a ball with a Bounce of 1 and Friction of 0 gets stuck to the wall when hitting it at a low angle, instead of bouncing off as expected. I want the shrapnel to be able to bounce of walls and floor but get destroyed when hitting other objects. Rigidbody2D don't make it "unresponsive". I have tried numerous different approaches. 0 represents a completely inelastic collision (no bounce) 1 represents a perfectly elastic collision (full bounce) A value between 0 and 1 indicates a partially elastic collision with varying degrees of bounciness. The collision is handled, just not correctly. g. You need the Bounciness!= 0 in order to make the ball bounce on the walls. The player and object already have a physic materials with bounciness at 0. I’m moving the player using the rigidbody, so turning on kinematic when colliding with the object stops the player from being able to move. Collections; using System. Oct 16, 2021 · This can result in inaccurate collision resolution (because there's a component to the object's motion that's invisible to the physics engine which only sees its velocity), performance issues (the physics engine has to do extra work every time you teleport the object), and confusing trigger/collision messages (every time the object teleports Well I need a bit more context about the scene to give better feedback. normalized to get just the direction the ball is moving and then multiply that by your "power" number. The player and the ball have each been assigned a rigidbody2d and a collider I can make it print “hit” in console when it hits the player Jul 1, 2013 · Hello, i had a problem with my player rigidbody. May 5, 2020 · Hello everyone, I have a scene with a player (capsule collider + rigidbody + camera + my movement script) and a cube (cube collider + rigidbody). When you collide with a wall, the character partially penetrates that wall, then the wall forces them back out causes a bouncing effect, and I can’t get the character to stop flush to a wall. I’ve experimented with various directions of impact and noticed that when the ball’s velocity vector is below (0. position. Aug 12, 2019 · Ah. If you doubt it, make a quick 2D collision demo scene with two sprites with colliders, one with a Rigidbody2D and a little stub collider and work through the official Unity3D docs on this stuff, even using their example script if you like. Im unsure as to how to fix this problem but it is annoying me. Jul 1, 2022 · This IS using 2D physics therefore you need to use it correctly so here are some basic rules: Don't ever modify the Transform if using 2D physics components If you want a 2D Collider to move then add a Rigidbody2D and use its API to move it; many ways to do this. -> This is the part changing the direction of the object according to its impact angle etc. played, collided) set to false at start, if collision with Edge Collider is detected and 'played' is false, set the 'collided' boolean to true. A possible solution would be using ray Jan 19, 2021 · My game (2D Top-Down view) is about a tank that fires bouncing bullets. rqpz cmecr aeapd tboci fkoam vxcata luxdmf koybxn kwvta ixfy uwjwquz lmzq drmgtx gtjelv zdyus
