Its what it says on the tin. When the player jumps and tries to wall grab the player launches into the sky.
here is the script I'm using for my climbing.
#Jumping while wall grabbing launches the player into the sky
gloomy kernel
from a bit of testing it also only seams to happen when the player is not directly up against the wall.
fossil scarab
from a bit of testing it also only seams to happen when the player is not direct...
PHYZRB.AddForce(transform.position * moveToLedgeForce, ForceMode.Impulse);```not sure what this is supposed to be doing but using a position as a force vector is a recipe for wacky stuff
gloomy kernel
```cs
PHYZRB.AddForce(transform.position * moveToLedgeForce, ForceMode.Impulse);...
what do you mean?
fossil scarab
Another problem here:
PHYZRB.linearVelocity = new Vector3(PHYZRB.linearVelocity.y, climbspeed , PHYZRB.linearVelocity.z);```
You're plugging y into the x fieldI mean exactly what I said. transform.position as input to AddForce is crazy.
THink about what that means.
If that code runs when you're standing at world 0,0,0, it does nothing.
If that code runs when you're 100 meters away to the east, at (100, 0, 0), it will fling you to the east very quickly
basically it's going to do something wildly different depending on where in the universe you are standing when it runs
I'm not sure what your intention was with that code, but that can't be right
I actually think the second issue with plugging y into the x slot is probably causing the issue you're describing though
gloomy kernel
```cs
PHYZRB.AddForce(transform.position * moveToLedgeForce, ForceMode.Impulse);...
Oh i see. my goal with it was that it would push the player up against the wall.
fossil scarab
Oh i see. my goal with it was that it would push the player up against the wall.
you would need to calculate a direction vector from the player's position towards the wall
transform.position ain't it
gloomy kernel
ok so how would I do that.
I have working sphere cast would convert that to something.
fossil scarab
A simple approach would be to store the hit.point from your spherecast
then you can calculate a direction vector from the player to that point with:
Vector3 direction = (spherecastHitPoint - transform.position).normalized;```The vector from A to B is always B - A
gloomy kernel
ok thank you I try that out and I'll get back to you.
ok I'm sorry I'm still a little new to this how would I store a hit.point?
gloomy kernel
ok how would I do that.
fossil scarab
do what
gloomy kernel
find the hit.point
gloomy kernel
oh lol I'm just over complicating it in my head
so this
wallfront = Physics.SphereCast(transform.position, sphereCastRad, Orientation.forward, out fromtWallHit, detectionLedngth, whatIsWall); ?
ok ok so something like this
Vector3 direction = (fromtWallHit.point - transform.position).normalized;
gloomy kernel
then you can calculate a direction vector from the player to that point with:
``...
@fossil scarab ok I'm not full sure what to do with this.
ok I think I'm getting but in the documentation you sent they uses this thing called ray. what is it. it doesn't say anything on it.
fossil scarab
ok I think I'm getting but in the documentation you sent they uses this thing ca...
you're already doing your spherecast
you're gettign confused by their example
the whole point of the example is to show that you can use hit.point, that's all
you can ignore the rest of it
in your code you named the RaycastHit something else though
so naturally you would use that
gloomy kernel
ok so this is correct
Vector3 direction = (fromtWallHit.point - transform.position).normalized;
then i take the "direction"
and use it like this?
fromtWallHit.rigidbody.AddForce(???.direction * moveToLedgeForce, fromtWallHit.point);
@fossil scarab
fossil scarab
It seems to me like you're still struggling with the basics of C#
that's going to make it kinda hard to do this stuff
fossil scarab
sort of... but you need to learn how to use variables and call methods.
You should look at what parameters AddForce takes as well
gloomy kernel
ok so then what would I put in the "???" spot I tried my raycast and that didn't work.
fossil scarab
why do you need something in the ??? spot
you need to store the position in a variable
and then just use the variable
gloomy kernel
because it wants something there.
fossil scarab
You would either use a field: https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/fields
Or pass the variable around as a method parameter: https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/methods
fossil scarab
because it wants something there.
you're getting confused because you don't understand variable scope
you can't use a variable from another scope like that directly
gloomy kernel
I get what a field is I understand methods.
I'm just confused what I need to be doing.
gloomy kernel
ok let me just start form the top. I'm sorry this is a struggle for me I just can't learn from just reading I need to actually do it.
So this " wallfront = Physics.SphereCast(transform.position, sphereCastRad, Orientation.forward, out fromtWallHit, detectionLedngth, whatIsWall);" is my hit.
I take this wallfront and use it like this
"Vector3 direction = (fromtWallHit.point - transform.position).normalized;"
Right?
fossil scarab
ok let me just start form the top. I'm sorry this is a struggle for me I just ca...
fromWallhit is the RaycastHit
you should extract the point from it and store that in a variable
e.g.
myVariable = fromtWallHit.point;```Then later:
Vector3 direction = (myVariable - transform.position).normalized;```thank you.
fossil scarab
the variable will need to either be a field, or passed via method parameters to be used in the other method
gloomy kernel
ok I got that. So then next I would just mimic this
"hit.rigidbody.AddForceAtPosition(ray.direction * pokeForce, hit.point);" from the docs
fossil scarab
ok I got that. So then next I would just mimic this
"hit.rigidb...
is there a reason you want to use AddForceAtPosition now?
Your original code was just using AddForce
gloomy kernel
oh no thanks for catching that.
fossil scarab
The example code from the docs were just showing you that hit.point exists basically. The entire rest of it is just an example that you don't want to copy unless you happen to be doing exactly what the example was doing
which you aren't
gloomy kernel
its defiantly smother but still its launching the player up.

calm trail
yes
now, what's the current issue? is it still the same issue of launching the player up?
gloomy kernel
yes thats the main issue
calm trail
well, this script only affects the rigidbody in 2 places
if you comment one or the other out, do you still get launched?
if you do, then the cause isn't in this script - it may be something else that is kinda fighting this one
gloomy kernel
what do you mean two places?
do you mean the PHYZRB.AddForce(direction * moveToLedgeForce , ForceMode.Impulse);
calm trail
yes, that and setting the velocity on line 134
i meant to mention them and forgot, mb
gloomy kernel
ok so I did disable one and I was still dealing with the issue.
calm trail
and what if you disable the other?
gloomy kernel
the one at 134

(and do make sure you're saving & compiling when testing)

what about it

and what if you disable the other?
oh sorry I'll check

Vector3 direction = (wallHitVar + transform.position).normalized;
this doesn't seem right
a vector from A to B looks like B - A, not B + A
gloomy kernel
I tried that but when I did I would move backwards.
ok and when I do the one at line 59 the player dose not move to the wall.
