I am making an FPS game using unity 3d, I've a problem in the shooting accuracy script. Can you tell me how I can change it with a single script that shoot the bullet and include the shooting accuracy and equipped to the gun, please?
If you are currently using a raycast, you should have no problem.
If you are spawning a sphere and thrusting it forwards, I suggest you use a raycast.
Raycasts go in a completely straight line. Bullets follow gravity, and quickly fall to the ground.
You don't see bullets, they move too fast. Raycasts are invisible.
When it hits something, it sends you back the information you need. If you make the sphere go too fast, it might glitch through objects.
You can learn about raycasts here.

I would like to try and make a game similar to Altos Adventure. I am having trouble starting.
How to set up the terrain so that my character doesnt get stuck?
I simply drew a test sprite for the ground in photoshop. What collider2d should I use?
I use polygon collider and reduce friction in the material. But the character gets stuck, hits small invisible bumbs and it feels awful. The worst part is connecting 2 ground sprites together! The point where they connect is always messy.
I have a question for the future as well. How would I add the endless part of the game?
Would having many "pieces" set up and just spawning them as the player rides down work?
I havent written any code yet as the problem is simply in the physics in my opinion.
Thanks to anyone who takes the time and tries to help!
To move your player use rigid body.AddForce(Vector3 direction, ForceMode forceMode); then create a Physics Material with friction = 0 and put it in your player's collider.
I am trying to make some kind of simulation program with Unity. The simulation includes a missile launched from an aircraft and a terrain.
I get the coordinate data required for the movement of the missile from another program using a socket connection.
I created an explosion effect for the missile to explode as soon as the missile and the terrain collided. But the explosion effect is not triggered in any way.
I used the OnCollisionEnter() method to detect the collision, but this method does not seem to work.
The missile has its own rigidbody and collider and The terrain has Terrain Collider, but still no collision is detected and the missile passes through the terrain.
What could be the cause of this error?
EDIT :
I thank everyone for their help, but none of the solutions worked. I solved the error using the OnTriggerEnter method. For this, I also had to enlarge the object's collider a little more.
As mentioned in the comment section above (I dont have enough rep to contribute to the discussion but will provide a solution), you need to enable continuous collision detection. Once you have done that we can move onto the next step.
It is generally bad practice to interact with rigidbodies in update and it can lead to all sorts of strange bugs so I wouldn't recommend it. That being said I dont think it's the cause of your issues. As #HumanWrites mentioned, you are manually moving the position each frame which causes your missile to never actually collide with your mesh. the solution to this is:
rb.MovePosition(Vector3.MoveTowards(...))
The reason for this is that by using the method on the rigidbody, you inform the physics engine that you want to move from one position to the other and you would like the physics to take care of this instead of you doing it directly. This allows it to "sweep" between the current position and target position and detect any collisions that would have happened along the way.
Your missile is moving too fast to ever actually touch the mesh within a frame so you need to rely on the physics engine doing that sweep check.
Kinda what the title says, I have a "wall" made out of multiple segments specifically for modular purposes. I have a contactTestBitmask that forces the player to stop moving in the direction of the wall once collided, but, if you slide along the wall to another segment, the player just rolls straight through it. I cannot do a collisionBitmask as the player runs fast enough to "phase" through the walls. I also cannot do collision as my camera and lighting are also dependent on the player's movement and position, and will not interfere with the walls (I think). If anyone could help point me in the right direction to allow me to make solid modular walls, I'd greatly appreciate it.
Figured out the source of my problem, contact IS happening, I just have wonky flags and the system doesn't like that. I need a contact currently happening method, I guess
I am trying to create a block breaker game in Unity 3D but I am having problems (this is my first time creating a game). When I throw the ball it ends like this https://gfycat.com/LimitedVagueAnkole. The physics between the ball and the bricks should be problematic i think but I don't know why. My ball's material is frictionless and its bounciness is 1. My bricks materials are None (physics material).
I can send more info if it helps but I don't really know what else to send.
PS: I didn't code the breaking of the bricks yet. I just don't understand why the ball isn't acting the way it should.
The same thing is happening to me, I think I have a solution for this problem. I think the reason why the ball keeps bouncing at one place is because the ball didn't have much speed to escape from the loop. Try increasing the speed of the ball a bit and you could see the ball indeed escape bouncing at one particular angle.
I am making a 2D Brick Breaker game in Unity.
I have an issue with the scenario when ball hits in between two bricks. I have BoxCollider2D attached to all bricks and a CircleCollider2D attached to the ball. When the ball hits between 2 adjacent bricks, it bounces back in the same direction as if it hit the edge of the brick. There is no edge in between, but two adjacent bricks form a continuous surface. So, the ball should bounce off of the surface (in other direction) instead of bouncing back.
Anyone knows of any solution to tackle this problem? I asked this in the Unity Physics forums but didn't get any answer, so checking if anywhere here might have had this issue.
Thanks,
Mukul
I am guessing this could be the problem:
When your ball is hitting the bricks with a strong force, There is a chance it might move one of the bricks by a very very slight distance, even if the mass of the brick is much heavier.
This movement might cause an uneven surface, which is why the ball bounces back in the same direction.
Try adding a Rigidbody Component on every brick (if you have not done it already), and set its isKinematic property to true.
Let me know if this solves it.
Way 1:
Use one box collider for the wall, but not for every single brick.
This will fix your issue + will optimize your project.
Way 2:
You need to build wall programmaly and colliders in this case must be without spaces between them. This must fix the issue.
Way 3:
Make your own hitting wall logic.
OnColliderEnter you need to get balls velocity.
OnColliderEnd you need to set manually velocity.
