Hello everyone, how are you doing? I'm trying to do something here and if you guys could help me somehow it'd be nice, I'm already grateful for your attention.
The thing is I was able to achieve the "rotation around a point" for Sprites ( in this case a circle ), but the issue is that I want to have multiple objects rotating around a point while starting at different "steps" of the rotation itself ( I'm attaching a image to explain it in more detail).
The code I'm using is the following:
MAIN.LUA
--sincos math timer=0 scr={ w=128, h=128 } opt={ spd=.5 } pix={ c=12, x=0, y=0 } cir={ timer=0, a=false, spd=.5, init=3, o=20, c=12, x=0, y=0, r=6 } function _init() cir.x=scr.w/2 cir.y=scr.h/2 pix.x=scr.w/2 pix.y=scr.h/2 end function _draw() cls(1) pset(pix.x,pix.y,pix.c) print("speed "..opt.spd) for entry in all(circles) do circ(entry.x,entry.y,entry.r,entry.c) end end function _update60() update_keys() for entry in all(circles) do entry.timer+= entry.spd/60 entry.x= pix.x+cos(entry.timer)*entry.o entry.y= pix.y-sin(entry.timer)*entry.o end if(keys.down) then opt.spd-=.1 elseif(keys.up) then opt.spd+=.1 end if(keys.right) then pix.x+=1 end if(keys.left) then pix.x-=1 end if(keys.activate) then make_circle(pix.x,pix.y,opt.spd,15,12) end if(keys.delete) then circles={} end end -- methods -- -- make_circle(x,y,s,o,c) |
UTILS.LUA
--utils circles={} function make_circle(x,y,s,o,c) local obj={ timer=0, a=false, spd=s, o=o, c=c, x=x, y=y, r=6 } add(circles,obj) end function update_keys() keys={ activate=btnp(🅾️), delete=btnp(❎), right=btn(1), down=btnp(3), left=btn(0), up=btnp(2), } end |
Thanks in advance for any help and have a good day!
