hi

static trout Dec 2, 2022, 1:55 PM

#

bruh

static trout Dec 2, 2022, 1:55 PM

#

topaz oak hi

ok what can i do

topaz oak Dec 2, 2022, 1:56 PM

#

OK so let me get this right, you want the coins to spawn randomly, right?

#

within a certain radius

static trout Dec 2, 2022, 1:56 PM

#

exaclty

topaz oak Dec 2, 2022, 1:56 PM

#

OK that should be easy

#

make a script called CoinSpawner or something similar

static trout Dec 2, 2022, 1:56 PM

#

LETS DO IT

topaz oak Dec 2, 2022, 1:57 PM

#

alright firstly, do you know what arrays are?

static trout Dec 2, 2022, 1:57 PM

#

done

#

no

topaz oak Dec 2, 2022, 1:57 PM

#

do you know what ints are

static trout Dec 2, 2022, 1:57 PM

#

wtf is arrays

static trout Dec 2, 2022, 1:57 PM

#

topaz oak do you know what ints are

yep

topaz oak Dec 2, 2022, 1:57 PM

#

do you know what gameobjects are

static trout Dec 2, 2022, 1:57 PM

#

ofc

topaz oak Dec 2, 2022, 1:57 PM

#

just double checking to see how in depth i have to explain this 😄

#

i'm a games programming student so im learning this stuff aswell

static trout Dec 2, 2022, 1:58 PM

#

cool

topaz oak Dec 2, 2022, 1:58 PM

#

alright, firstly you want to make a private gameobject called coins

static trout Dec 2, 2022, 1:58 PM

#

got u

#

this is how i type GameObject

#

or Gameobject

#

or gameObject

topaz oak Dec 2, 2022, 2:00 PM

#

should look something like this

#

don't forget the [SerializeField] and the [] on the gameobject

#

and obviously call the points coins

static trout Dec 2, 2022, 2:00 PM

#

and

topaz oak Dec 2, 2022, 2:01 PM

#

have you done that?

static trout Dec 2, 2022, 2:01 PM

#

yep

topaz oak Dec 2, 2022, 2:01 PM

#

Okauy

#

okay

#

the thing is im not sure how this is gonna work as its 2d but im still happy to try

static trout Dec 2, 2022, 2:02 PM

#

ok

topaz oak Dec 2, 2022, 2:02 PM

#

now head to unity and make a gameObject called Waypoints/CoinPoints etc

#

static trout Dec 2, 2022, 2:02 PM

#

and

topaz oak Dec 2, 2022, 2:02 PM

#

should look like this

static trout Dec 2, 2022, 2:03 PM

#

it does

static trout Dec 2, 2022, 2:04 PM

#

topaz oak should look like this

hello?

topaz oak Dec 2, 2022, 2:04 PM

#

hi

#

be more patient

static trout Dec 2, 2022, 2:05 PM

#

ok lets complete

static trout Dec 2, 2022, 2:05 PM

#

topaz oak be more patient

sorry

topaz oak Dec 2, 2022, 2:06 PM

#

OK now make 3 gameobjects as children of Waypoints or whatever you call it

#

and call them Spawnpoint 1, 2 and 3

#

should look something like this

static trout Dec 2, 2022, 2:07 PM

#

and

topaz oak Dec 2, 2022, 2:07 PM

#

so when you click the down triangle everything collapses

static trout Dec 2, 2022, 2:07 PM

#

ok

topaz oak Dec 2, 2022, 2:08 PM

#

does that happen?

static trout Dec 2, 2022, 2:08 PM

#

what?

topaz oak Dec 2, 2022, 2:09 PM

#

topaz oak so when you click the down triangle everything collapses

.

static trout Dec 2, 2022, 2:09 PM

#

topaz oak .

yea it did

#

now?

topaz oak Dec 2, 2022, 2:09 PM

#

nice okayu

#

now click on waypoint 1

static trout Dec 2, 2022, 2:09 PM

#

and

topaz oak Dec 2, 2022, 2:10 PM

#

#

click on this dropdown menu

static trout Dec 2, 2022, 2:10 PM

#

and

topaz oak Dec 2, 2022, 2:10 PM

#

it should have loads of colours

#

with shapes

#

click any of them

static trout Dec 2, 2022, 2:11 PM

#

and

topaz oak Dec 2, 2022, 2:11 PM

#

then do it for every waypoint

#

it can be the same colour

#

should be the same colour*

#

then send me a screenshot

static trout Dec 2, 2022, 2:13 PM

#

topaz oak Dec 2, 2022, 2:13 PM

#

make them the same colour and move them to where you want the coins to spawn

static trout Dec 2, 2022, 2:13 PM

#

like on them

#

or in the raduis

#

betwwen them

topaz oak Dec 2, 2022, 2:14 PM

#

show me your whole screen

static trout Dec 2, 2022, 2:14 PM

#

topaz oak Dec 2, 2022, 2:14 PM

#

ok make all the colors the same for the spawnpoints

static trout Dec 2, 2022, 2:14 PM

#

and

topaz oak Dec 2, 2022, 2:15 PM

#

just for now, put 1 in each corner

static trout Dec 2, 2022, 2:15 PM

#

of the map?

topaz oak Dec 2, 2022, 2:15 PM

#

#

just for now

#

😄

static trout Dec 2, 2022, 2:16 PM

#

and

topaz oak Dec 2, 2022, 2:16 PM

#

also you need to learn putting stuff in right folders but well do that later

#

make an empty game object called 'Spawner' and drag the script on to Spawner

static trout Dec 2, 2022, 2:19 PM

#

and

topaz oak Dec 2, 2022, 2:22 PM

#

you did that, yea?

static trout Dec 2, 2022, 2:22 PM

#

yea

topaz oak Dec 2, 2022, 2:22 PM

#

okay now go to the inspector, it should look like this

#

#

click the + and drag the waypoints you made in there

static trout Dec 2, 2022, 2:23 PM

#

yep

#

wait

#

where do i add the script on the spawner

topaz oak Dec 2, 2022, 2:25 PM

#

drag it

topaz oak Dec 2, 2022, 2:25 PM

#

static trout where do i add the script on the spawner

yes just drag the script to the inspector

static trout Dec 2, 2022, 2:25 PM

#

topaz oak yes just drag the script to the inspector

bro this is what it looks like this

topaz oak Dec 2, 2022, 2:25 PM

#

did you do it then

static trout Dec 2, 2022, 2:25 PM

#

topaz oak Dec 2, 2022, 2:26 PM

#

show me the script

static trout Dec 2, 2022, 2:26 PM

#

topaz oak Dec 2, 2022, 2:26 PM

#

topaz oak don't forget the [SerializeField] and the [] on the gameobject

.

static trout Dec 2, 2022, 2:27 PM

#

i add it

#

oh sorry

topaz oak Dec 2, 2022, 2:28 PM

#

ok now save

#

and re run

#

then show me it again

static trout Dec 2, 2022, 2:29 PM

#

done

topaz oak Dec 2, 2022, 2:30 PM

#

nice now go back to the script spawning

#

you're very new to coding, aren't you

static trout Dec 2, 2022, 2:30 PM

#

yep

#

but not that new

#

i coded before

#

for like 3 days

topaz oak Dec 2, 2022, 2:30 PM

#

you need to name your scripts something easier and memorable

topaz oak Dec 2, 2022, 2:31 PM

#

static trout for like 3 days

thats nothing xD

topaz oak Dec 2, 2022, 2:31 PM

#

topaz oak you need to name your scripts something easier and memorable

and not so rude

static trout Dec 2, 2022, 2:31 PM

#

topaz oak thats nothing xD

ok

topaz oak Dec 2, 2022, 2:31 PM

#

wait go back to unity quickly

static trout Dec 2, 2022, 2:31 PM

#

why?

topaz oak Dec 2, 2022, 2:31 PM

#

#

click on this

static trout Dec 2, 2022, 2:32 PM

#

i will add a tag and name it waypoint

#

just a min

topaz oak Dec 2, 2022, 2:32 PM

#

#

tag it waypoint

#

yeah

static trout Dec 2, 2022, 2:32 PM

#

done

topaz oak Dec 2, 2022, 2:33 PM

#

nice

#

now uhh go back to the script

static trout Dec 2, 2022, 2:33 PM

#

and

topaz oak Dec 2, 2022, 2:35 PM

#

in your start function you need to do coin = GameObject.FindGameObjectsWithTag("waypoint");

#

so it finds all of the waypoints you created

static trout Dec 2, 2022, 2:35 PM

#

i just stole your code

#

lol

#

what else

topaz oak Dec 2, 2022, 2:36 PM

#

now you need to make a vector2 function called getRandomSpawnPoints or something similar

static trout Dec 2, 2022, 2:36 PM

#

public or private

topaz oak Dec 2, 2022, 2:37 PM

#

up to you

static trout Dec 2, 2022, 2:37 PM

#

i will do public

topaz oak Dec 2, 2022, 2:37 PM

#

private makes more sense as it'll only be accessed in this script

static trout Dec 2, 2022, 2:37 PM

#

U SAID ITS UP TO YOU

topaz oak Dec 2, 2022, 2:37 PM

#

now inside your new function you need to make a Vector2 called pos

static trout Dec 2, 2022, 2:38 PM

#

dont know i think Vector2.pos

topaz oak Dec 2, 2022, 2:38 PM

#

Vector2 pos;

static trout Dec 2, 2022, 2:38 PM

#

topaz oak now inside your new function you need to make a Vector2 called pos

dont know how to make

#

it

static trout Dec 2, 2022, 2:38 PM

#

topaz oak Vector2 pos;

ok

topaz oak Dec 2, 2022, 2:38 PM

#

topaz oak Vector2 pos;

.

#

now on a newline, type pos.x =

static trout Dec 2, 2022, 2:39 PM

#

and

topaz oak Dec 2, 2022, 2:39 PM

#

pos.x = coins[Random.Range(0, points.Length)].transform.position.x + Random.Range(-7, 7)```

#

something like that

static trout Dec 2, 2022, 2:39 PM

#

wow thx i will steal that

topaz oak Dec 2, 2022, 2:40 PM

#

change points.length to coins.length

static trout Dec 2, 2022, 2:40 PM

#

didnt understand

topaz oak Dec 2, 2022, 2:41 PM

#

static trout Dec 2, 2022, 2:41 PM

#

like what i change

topaz oak Dec 2, 2022, 2:41 PM

#

the cofde

#

code

static trout Dec 2, 2022, 2:42 PM

#

what part

topaz oak Dec 2, 2022, 2:42 PM

#

points.length to fucking coins.length

#

its crossed out in the picture man

#

#

show me your script

static trout Dec 2, 2022, 2:42 PM

#

what do i change it into

topaz oak Dec 2, 2022, 2:43 PM

#

topaz oak points.length to fucking coins.length

.

#

whats so hard man

static trout Dec 2, 2022, 2:43 PM

#

topaz oak Dec 2, 2022, 2:43 PM

#

when you screenshot code show me the line numbers

static trout Dec 2, 2022, 2:44 PM

#

topaz oak Dec 2, 2022, 2:44 PM

#

you see in line 22

#

its the same code as the one ive screenshotted multiple times and shown you what to change what into

#

do the same in your code

static trout Dec 2, 2022, 2:45 PM

#

ohhhhhhhhhhhhh

#

now i understand

#

sorry

#

yay

#

now what

topaz oak Dec 2, 2022, 2:46 PM

#

now you need to do the same for Y

#

but you don't want random y right?

#

if you don't, remove the + Random.range at the end

static trout Dec 2, 2022, 2:47 PM

#

nvm

#

#

like that

topaz oak Dec 2, 2022, 2:54 PM

#

remmove the ramdon range at the end

static trout Dec 2, 2022, 2:55 PM

#

topaz oak Dec 2, 2022, 2:55 PM

#

ur code is monkey

static trout Dec 2, 2022, 2:55 PM

#

wdym

static trout Dec 2, 2022, 2:57 PM

#

topaz oak ur code is monkey

i thought you were a good man

topaz oak Dec 2, 2022, 2:57 PM

#

you only need 1 vector 2

#

called pos

#

not posx and posy

static trout Dec 2, 2022, 2:57 PM

#

ohhhhh

topaz oak Dec 2, 2022, 2:57 PM

#

topaz oak Vector2 pos;

because ur not doing what im saying to do

static trout Dec 2, 2022, 2:57 PM

#

cuz i dont understand

topaz oak Dec 2, 2022, 2:58 PM

#

you don't know basic coding so learn that before you start projects i guess

static trout Dec 2, 2022, 2:58 PM

#

anyways lets complete

topaz oak Dec 2, 2022, 2:59 PM

#

type 'StartCoroutine(SpawnEnemies());' in the start function

static trout Dec 2, 2022, 3:00 PM

#

and

topaz oak Dec 2, 2022, 3:00 PM

#

now make a new IEnumerator function called SpawnEnemies

#

static trout Dec 2, 2022, 3:01 PM

#

and

topaz oak Dec 2, 2022, 3:02 PM

#

show me the script

static trout Dec 2, 2022, 3:02 PM

#

topaz oak Dec 2, 2022, 3:02 PM

#
