please, not another sans fight...

"THE LIBRARY DOESN'T WORK"

yes, it does. there's a lot of people who use it. you're just using it wrong. stop blaming my library and just ask for help on the unitale server, thanks.

HI IF YOU USE THIS PLEASE CREDIT ME FOR SOME REASON PEOPLE DONT

!! if you encounter any issues WITH THE LIBRARY ITSELF, my discord is Ally 🌠#1540. i will not be giving help to people that aren't using the library correctly !!

heres a video of it in action. https://ringo.is-a-good-waifu.com/7N1pvcA.mp4

✨✨✨ HOW TO USE ✨✨✨

throw blasters = require ("Libraries/gaster_blasters") at the bottom of your wave script

throw blasters.Update() somewhere in your update function, you should probably put that at the bottom

to create a gaster blaster, use blasters.New

blasters.New(start_x,start_y,goto_x,goto_y,rotation[,startrotation[,sound[,fire_sound[,sprite_prefix[,beam_sprite]]]]]) returns GasterBlaster

!! anything in square brackets are optional and have default arguments !!

start_x and start_y are where the gaster blaster spawns, this is normally off screen

goto_x and goto_y are where the gaster blaster moves to, this is normally on screen

rotation is where the gaster blaster turns to face

startrotation is what the gaster blaster starts out as, this is 0 by default as thats what undertale does im pretty sure

sound is "gasterintro" by default, if you set it to false then the blaster is silent

same with fire_sound except it's "gasterfire" by default

sprite_prefix is "blaster/spr_gasterblaster_" by default

beam_sprite is "blaster/beam" by default

✨✨✨ variables and functions ✨✨✨

GasterBlaster.Scale(width,height) rescales the gaster blaster, if you set width to 0.5 and height to 1 its just like the small ones in undertale

these get cleaned up when the wave ends but if you want to instantly destroy one call GasterBlaster.Destroy()

GasterBlaster.x is its x position, note that itll try and move to x2

GasterBlaster.y is its y position, note that itll try and move to y2

GasterBlaster.x2 is where the blaster is trying to move to

GasterBlaster.y2 is where the blaster is trying to move to

GasterBlaster.shootdelay is how long until the blaster shoots its beam, 40 by default

GasterBlaster.speed is how fast it moves/turns, default 40

GasterBlaster.angle is its angle, you can modify this and nothing bad should happen probably

GasterBlaster.holdfire is how long it stays in place before moving away after firing, 0 by default

GasterBlaster.beam is the beam projectile, you shouldn't overwrite this

✨✨✨ the single event that this library has ✨✨✨

GasterBlaster.OnBeam(bullet) gets called when the blaster shoots its beam. bullet is the beam (its a projectile btw)

a good example of this being used is colored blasters

local my_super_cool_blue_blaster = blasters.New(320, 480, 320, 300, 0, 0)
my_super_cool_blue_blaster.sprite.color32 = {0,162,232}
function my_super_cool_blue_blaster.OnBeam(bullet)
    bullet["color"] = "blue"
    bullet.sprite.color32 = {0,162,232}
end
function OnHit(bullet)
    if bullet["color"] == "blue" and Player.ismoving then
        Player.Hurt(1,0)
    end
end

in this wave (which is missing a few things but you get the point) creates a blue gaster blaster.
