When should i use lerp()

[red yarrow]

i understood the difference between tweenservice and lerp.
a guy said that lerp is better with physics and real time calculations and it uses less network usage.
so can someone give me an example (like a small system) where it is better to use lerp()

Use lerp() when you want to smoothly move or change a value yourself every frame, instead of using a Tween animation.

[red yarrow]

should't tweenservice be smoother?

[kind plume]

not necessarily

[red yarrow]

wait u mean on the server

if its on the server yes

i think lerp is better

lerp gives you more control over the interpolation of an object/value.

Usually you will use lerp() on physical objects because it can change while the object is in motion. (In a heartbeat for example)

Tween service runs on 1 animation and when you call :Play or wtv it’ll follow that A -> B trajectory no matter what.

This is the general usage in a practical sense: https://devforum.roblox.com/t/how-do-i-make-pet-follow-system/3308281/4

basically tween service isnt accurate for moving stuff it might overshoot , lerp never overshoots its basically good for projectiles

Last sentence is false

You can use tweenservice:getvalue

Research it

It’s like lerp but with easing styles

[boreal fox]

it’s only used to move an object once, not follow

[restive zenith]

Did you read what I sent or only glance over it

[boreal fox]

He said Tween service runs on 1 animation, dont know why you said the last sentence is false even though it does.

[restive zenith]

I said it’s false because it is

Big misconception

When you create a tween yes it is one animation

But when you incorporate getvalue then you can have it almost exactly like lerp but with easing styles

Lerp is linear interpolation

Getvalue lets you interpolate based off of easing

I don’t understand why it’s so hard to just simply google getvalue

💔 💔

Are you still gonna persist with your misinformation or will you take five minutes of your time to research what I told you to

[hearty arch]

tween is lerp tho https://create.roblox.com/docs/reference/engine/classes/TweenService#GetValue they have mildly different use cases but fundamentally the same tech. it's like saying a plate is better than a bowl - the comparison just doesn't make any sense.

[lone jasper]

yeah but why the fucj would you ever do that

i know you can pause and resume like a lerp technically

but its like

why

just lerp

i see you can use getvalue but i feel like (maybe im wrong ive never used it) it’d end up making the interpolation look a little bit more choppy if you’re not careful

you can make both of them work but like why with the extra overhead

[restive zenith]

You can pause and resume tweens too

I never use getvalue

But it’s just clearing up what he was thinking
