please The MovementScript Lincked White full Script pleaseeeeeeeee grapling ,walk run,and....

[@youdi615]

I watched all your tutorials in 1 day and implemented everything so far. Best tutorials on youtube hands down.

[@youdi615]

Also, I am getting an error while trying to grapple if I'm not moving. I've narrowed it down to this part of the code returning NaN and messing the whole thing up: Mathf.Sqrt(2 * (displacementY - trajectoryHeight) / gravity). Is there any way to fix this? Like skipping the function if the player does not have enough velocity.

[@youdi615]

For anyone facing the same issue, I fixed this by taking the absolute value of the discriminant of that piece of code. So it will look like this... Mathf.Sqrt(Mathf.Abs(2 * (displacementY - trajectoryHeight) / gravity)) With this, youll still be able to grapple when standing still it just wont pull you in a lot, but if you run and have momentum the grappling will work just fine.

[@davegamedevelopment]

Thanks so much man, appreciate it! :D

[@davegamedevelopment]

Also this NaN error usually happens when you pass in a negative value for the trajectory height to the CalculateJumpForce function(), just make sure it's positive!

[@bizi-e3v]

Hey Dave I’ve used your tutorials for less than a day and I think they are very good and they add quite a lot of depth to a game. Could you make a tutorial on how to add headbobbing and maybe arm bobbing for holding a weapon?

[@ind1ewave]

Just as I finish ledge climbing this comes out, so helpful!

[@davegamedevelopment]

Thanks, great to hear!

[@Enderking394]

[@awmeil1382]

Amazing tutorial! I am currently developing my own game and this stuff helps alot, I will admit the only problem im having is Animations as youve made a quite clear explination on where things go and why they are being used. I cant seem to grasp the animations yet.

[@davegamedevelopment]

Thanks a lot! And yes, animations can be a bit tricky, maybe I'll make a tutorial on that sometime :D

[@TerraOnHere]

Ive been looking for this for sooo long and now you upload it thank you legend

[@davegamedevelopment]

You are the best your tutorials are helping me so much you should keep on going with these tutorials bro thanks!!!

[@davegamedevelopment]

Thanks man, appreciate it!

[@OsrsNooby]

Thank you for continuing to upload tutorials, very helpful What about grappling to moving objects? The hook stays where the object was when it hit, instead of moving with the object if I'm not mistaken. How would we have it stay attached to the object so it drags the player along with it?

[@davegamedevelopment]

Sure man, glad you like them!

[@matthewmartin283]

So awesome dude! Could you make an updated wall running video on how to run diagonally across walls as well? Meaning you can run right/left/up or diagonally in any upwards vertical direction!

[@davegamedevelopment]

I think my latest wall running tutorial covers that :D

[@Strangertoyourlife]

Really love the info your giving, it would be good if it wasn't tied too heavily into your own movement script and was its own thing so others wanting to use it could add it to their own character controllers etc.

[@davegamedevelopment]

Appreciate the feedback, thanks!

Sorry for a negative comment ur tutorial really does work but pls keep a mindset that the people probably dont watch ur videos video by video bcs i was tryna fix and issue with the freeze thing that freezes u it for some reason wasnt using a reference or something broke and then while trying to fix it i somehow deleted 2 hours of work following your tutorial but still ur tutorials are great only comment

Hey man! Can you please make some a tutorial on how to climb stairs? Not like just setting the mesh collider of stairs to convex but actually stepping up staires and little sharp bumps in the ground using things like raycasts a d moving the player up

Stair movement is one of the hardest things to code when it comes to player movement, but I'm planning to cover it sometime yes :D

[@ultmatepotato]

@@davegamedevelopment from what i can tell it wont be comig out in awhile so i just wanna ask a question. Is it okay to do two raycasts stacked upon eachother to see if its a stair and can be climbed then lerping the player pos i nthe y axis the little bit to climb stairs?

You Can inrease damping so that you can swing when velocity is enough and grapple when standing

[@emilian_spielt300]

Idk why but it saids: The type or namespace name "PlayerMovementGrappling" could not be found anyone help?

[@davegamedevelopment]

Did you follow along with my movement tutorial? If so, you then need to change the "PlayerMovementGrappling" variable to whatever your script is called, probably "PlayerMovementAdvanced" or something like that :D

[@Alex-Tomato2KindGold]

you are a holy virtue thank you so much for this coding. you can really make a good game with this.

[@Victoro]

I followed the tutorial but for some reason my line renderer is not drawing when i use the grappling hook. Any ideas why is this happening? :(

[@sofiaonaga5352]

Check your spelling and if it's on Caps lock on any word, maybe. That's what worked for me, and it was really annoying. 🤣

[@NikohKoa]

@@sofiaonaga5352 When you bring up spelling, do you mean in code or in the editor? Any specific spots that affect the code for this problem?

[@bentoudal]

Almost wish you'd put in the description, which videos of yours you recommend we watch first. Love the content though and it's generally easy enough to follow, though I gave up on bugfixing my slope movement. I rewatched your video countless times and did exactly as you did, but my Raycast seems to "forget" that I'm on a slope for a couple seconds, making me slide in the direction I was walking, then regain control after a couple seconds.

[@HDCraft123]

Hi Dave! Im trying to make multiplayer but I dont know how and I really need help could you please make multiplayer tutorial

[@joseph3659]

Amazing tutorial! But how would I change the power of the grappling hook?

[@davegamedevelopment]

That's a bit hard honestly, since the physics calculation takes the current gravity into account. For example, if you fly up a certain hight, you need to "wait" for gravity to pull you down again - a process that can't be speeded up. Either you reduce the overshootYAxis value or you increase the gravity while grappling :D

[@scratchthegamedev9789]

Hey if anyone can answer it would be much appreciated I have a problem where my player is only being pulled up while grappling and it is barely being pulled forward I have already tried lowering the overshootYaxis but that just barely moves the player forward at all. Once again any answer or help would be appreciated!

[@zombee5546]

Yeah I'm having the same issue. Have you found a fix?

[@scratchthegamedev9789]

@@zombee5546 Yeah my problem was that the environment that I was using in unity was high in the air so my player was already high up meaning that the using the code "gravity = Physics.gravity.y" isn't really dependable if your player is high in the air originally or on a high platform so I made a variable called "GravityModifier" which was a float and I think I added or subtracted the variable by "physics.gravity.y" it would look like: "gravity = Physics.gravity.y + GravityModifier".

Hi Dave, is there a way to make the grappling from point a to point b much faster? if so, where should we add the line of code?

Reduce the overShootYAxis, that's the main thing you can do. The reason for this is that it takes some time for gravity to fully counter all upwards force which can not be sped up :D (Except if you increase the gravity while grappling, that would work too)
