Slice / Cut Parts - Roblox Scripting Tutorial

[@soma78]

Love how you take the time to explain the maths behind it. This is something definitely new, looking for a Roblox tutorial and not being treated like an 8 ys old child. Thanks, you got a new subscriber.

[@nreeda2744]

Thats hella too advanced

[@gcmvanloon]

Thank you for this. Apparently Roblox Studio does not support the GripRight and GripUp properties any more. I managed to accomplish the same result by adding an extra line in the server script: 'tool.Grip = CFrame.new(tool.Grip.Position + Vector3.new(-0.5, 0, 0)) * CFrame.Angles(0, 0, -math.rad(90))' Perhaps someone else finds this helpful one day.

[@Gen1us707]

just noticed this comment, i kinda did another version of it but using properties. if you want, i can delete it. its almost the same though, its saying to do 0, 0, -90 on the grip orientation.

[@TheoAnimates]

couldnt you have just changed grip orientation in the tool properties

[@Bogo.b]

Which line of the script is it to put?

[@Gen1us707]

updated grip area: now, theres a section for grip. its position, and orientation. position will be welded with the character, so don't worry about that. The orientation though, make it 0, 0, -90. If you observe correctly, its to the right of the player. Going left by 90 degrees gives 270 degrees, or -90.

i cant believe i wacthed a one hour video and it worked!, i appreciate how you are a good scripter, like if i watched a video like this but the video is 1 minute it wont work, thank you so so so much you earned a sub!.

[@grandtheftautoexpert2040]

Hi Suphi, I was wondering how the math is behind re-calculating vectorZ? I understand, that in reality it will not matter what the Y vector is, as long as the rotation and rough positioning of the CFrame is correct enough, therefore being that the Y vector doesn't have to be precise and can be alternated between the position of the camera or the tool, though I am confused as how that will always be exactly 90 degrees apart from the X vector, as you had mentioned in the video. Because of that issue you mentioned we have to recalculate the Z vector, but will it not yield the same result, as part of vectorY's value is vectorZ? Thanks!

[@-CENSORED0-]

Why is it whenever I change the size of the subtractpart, it just doesn’t work? 100x100x100 is the only size that works, but I want to make it bigger (It doesn’t identify the union as anything for a more specific reason)

[@LopityHipity]

If you feel like the sliced parts are delaying or stuttering after the cut, you can make it smoother by using SetNetworkOwner of the two unions to the player in the server script

[@whitewolf8763]

@@5uphi oh and for example anti god mode, anti flying ,anti steal tools, like a more complexe anti exploit and more complete would be amazing and yeah i saw ur videos about stopping hackers etc its very nice !

[@5uphi]

I think for anti steal tool you would need to make your own custom tool system and not use robloxes system for anti fly you would need to keep checking on the server side to see if the player is on the ground most likely by ray casting I have not looked into god mode but there are a few ways a exploiter could prevent themselves from losing health based on different things

[@kurbid]

ok wth is this man doing making the most indepth tutorials ever and being chill with 17k subs

[@askshells]

Can someone explain how he created two UnionOperations with the exact same parts to create the union, and the only thing he changes is the cframe so they both have different cframes, but when you slice the parts in-game, the two UnionOperations have different sizes?

[@Spooky.Studios]

You may also set 'CollisionFidelity' on the sliced parts to 'PreciseConvexDecomposition' for better collisions

[@yal1621]

the raycast collides with the targetpart so it stacks ontop of eachother to the camera

You must not of set the target parts properties like I showed in the video

[@WindyPivot]

how would you apply these cuts to a projectile? a slice of air that cuts parts it touches?

[@Whyuko-lh7mv]

Its simple and easy, 1 hour is enough for explaining the tools, W youtuber and simple scripts.

[@DaYoDuDe]

Hey @Suphi Kaner , great videos. I'm trying to utilize this slicing mechanic for a Fruit Ninja like game, but I'm running into an issue where the slice models sometimes doesn't slice. I think this is because the slicing doesn't behave well for moving parts. I get this error which occurs upon the first SubtractAsync(): " Result was empty, possibly because everything got subtracted away. " Any ideas as to how I can solve this?

[@Darkman-ur7ob]

i dont know if this is the actual reason but i think its because the actual laser or beam is moving by 2 studs which im pretty sure is the lowest he can do and it has to keep up with falling objects with 2 stud every time it has to move he also said in the video it tracks the starting point and the ending point to cut but it cant cut if it doesnt track the end or starting point thats why you cant just make holes inside it so with limited movement options i dont think its actually possible to fix this maybe with future techonlgy you could fix it or im competely wrong

If anybodys worrying about the union color on the inside just look in the normal script and look for the code local union2 = instance:SubtractAsync({subtractPart}) then under that put union1.UsePartColor = true union2.UsePartColor = true it should look like local union2 = instance:SubtractAsync({subtractPart}) union1.UsePartColor = true union2.UsePartColor = true then you got color all over the your cut stuff

[@seblind3474]

Hello! I really love your videos. Have you ever considered making a video on optimization or how to prevent memory leaks?

[@5uphi]

That's a hard topic to cover because there are so many different ways to optimize for different things for instance I have a video on greedy mesh that shows how to optimize voxels and I have a video on compressing data for datastore so there is not one rule to optimize all code depending on what your trying to do there will be different ways to optimize but I'll keep it in mind and if I workout some general rules you can follow I'll make a video
