Math animations and math.random

[weak yew]

how i can make it so in a math animation the math.random expression only gives 1 random value at a certain time and not generate random values everytime it can

[hardy grove]

Send the animation that you put together to do this.

[weak yew]

done

i can send you more files if you need it

[hardy grove]

Have you confirmed that the animation is actually playing?

[weak yew]

i use the /playanimation command

[hardy grove]

Oh that barely works for anything. What is the context of this?

[weak yew]

ill be back in some time got to go

[weak yew]

and the context is i wanna do some type of evocation fang that randomizes its size

[hardy grove]

Ah, so these entities just spawn, play the animation, and quickly despawn? You'll want to have the animations specified in the client side entity definition and played from there.

[weak yew]

ty but my problem now is with getting the animation to work

[hardy grove]

Gotta get the animation to play first.

If you set "scale" to, say, 5, does it reflect?

[weak yew]

like "scale": 5

[hardy grove]

Yeah.

[weak yew]

doesnt work

[hardy grove]

Okay, so that shows that the animation is not playing. Have the animation defined in the client side entity definition instead.

[weak yew]

so on RP/entities/test

[hardy grove]

Yeah that one.

RP/entity/test.json

[weak yew]

like this?

"animations":{
"animation_test":"animation.test.test"
}

[hardy grove]

And then also:

"scripts": {
  "animate": [
    "animation_test"
  ]
}

[weak yew]

it worked

the only problem is when i changed "scale" to "scale": "v.scale = v.scale ?? 0; v.anim_time = v.anim_time ?? q.anim_time; q.anim_time >= 3 && v.anim_time < 3 ? { v.scale = math.random_integer(1, 10); }; v.anim_time = q.anim_time; return v.scale;"

it didnt do nothing

[hardy grove]

So the "scale": 5 worked and the entity was 5 times the usual size?

[weak yew]

ye

[weak yew]

and it seems to run this one but instead of changing size the entity becomes invencible or size 0 i think

[hardy grove]

Try replacing v.scale = v.scale ?? 0; with v.scale = v.scale ?? 2;

[weak yew]

its visible but even after 3 seconds nothing happens

[hardy grove]

That shows that it's an issue with the animation timer logic.

[hardy grove]

Replace return v.scale; with return q.anim_time; and see what happens.

[weak yew]

the entities dissapeared

[hardy grove]

This suggests that the animation timer is not advancing.

[hardy grove]

Try replacing the whole thing with:

"scale": "v.scale = v.scale ?? 0; v.anim_time = v.anim_time ?? 0; v.anim_time + q.delta_time >= 3 && v.anim_time < 3 ? { v.scale = math.random_integer(1, 10); }; v.anim_time = v.anim_time + q.delta_time; return v.scale;"

[weak yew]

YO TYSM

it works perfectly

but how i make them smooth

because after 3 seconds it just pops

[hardy grove]

Do you want it to be a smooth transition into the random size over the course of those 3 seconds?

"scale": "v.size = v.size ?? math.random_integer(1, 10); v.anim_time = v.anim_time ?? 0; v.scale = v.size*math.sin(math.min(v.anim_time, 3)*30); v.anim_time = v.anim_time + q.delta_time; return v.scale;"

[weak yew]

if its possible yea

[weak yew]

just tried this one

its amazing

btw what are the ?? for

[hardy grove]

That is a null coalesce. It uses the first variable, unless it's undefined, then it uses the second variable.

It's good for initializing things.

[weak yew]

oh

you really good at this ty

and the ; ???

[hardy grove]

The semicolons just separate the different instructions.
