Framework for lua coding (includes touchscreen handling)
By Tajin
This is a framework (not a guide) that can be helpful when you want to make complex things in lua but need a way to keep your code compact and organized.

This framework contains:

1. shortcuts for most of the ingame commands (either to save some characters or if you're a lazy typer)

2. some useful minified functions that are often needed and that also help you to keep your code compact (like getting all your input variables in one go)

3. an easy and compact way to define buttons and add actions to them (supports clicking, holding or toggling those buttons)

~ ~ ~
I may also add some additional functions at the end that don't really fit into the framework but can still be useful in special occasions.
Feel free to let me know if you think something is missing.

Commented framework
Since the steam code-tags are apparently buggy, get the code here:
http://rising.at/Stormworks/lua/framework.lua

You may want to remove the commends and other parts you don't need, to keep the size reasonable.

Function: Drawing a rotated triangle (pointer)
M=math si=M.sin co=M.cos pi=M.pi S=screen dTF=S.drawTriangleF function drawPointer(x,y,s,r,...) -- position x,y, size, direction, angle/width of the arrow (optional) local a = ... a = (a or 30)*pi/360 x = x+s/2*si(r) y = y-s/2*co(r) dTF(x,y, x-s*si(r+a), y+s*co(r+a), x-s*si(r-a), y+s*co(r-a)) end
Function: Draw an arc
M=math si=M.sin co=M.cos pi=M.pi S=screen dTF=S.drawTriangleF dL=S.drawLine function drawArc(...) --x,y,radius,(angle1,angle2,filled,step) local x,y,r,a1,a2,pie,step = ... a1 = a1 or 0 a2 = a2 or 360 step = step or 22.5 if a2<a1 then a2,a1=a1,a2 end local a,px,py,ox,oy,ar = false,0,0,0,0,0 repeat a = a and M.min(a+step,a2) or a1 ar = (a-90) *pi /180 px,py = x +r *co(ar), y +r *si(ar) if a~=a1 then if pie then dTF(x,y, ox,oy, px,py) else dL(ox,oy,px,py) end end ox,oy = px,py until(a>=a2) end
Function: lua PID
Slightly different than the regular ingame pid. This one also automatically prevents windup.
function pid(p,i,d) return{p=p,i=i,d=d,E=0,D=0,I=0, run=function(s,sp,pv) local E,D,A E = sp-pv D = E-s.E A = math.abs(D-s.D) s.E = E s.D = D s.I = A<E and s.I +E*s.i or s.I*0.5 return E*s.p +(A<E and s.I or 0) +D*s.d end } end -- example pid1 = pid(0.01,0.0005, 0.05) pid2 = pid(0.1,0.00001, 0.005) function onTick() setpoint = input.getNumber(1) pv1 = input.getNumber(2) pv2 = input.getNumber(3) output.setNumber(1,pid1:run(setpoint,pv1)) output.setNumber(2,pid2:run(setpoint,pv2)) end --
Delays
delay = {"test"=60} -- setup initial delays function onTick() for i,v in pairs(delay) do delay = v>0 and (v-1) or nil end -- decrease all delays by 1 or clear them on 0

if not delay.test then -- do something after the first 60 ticks
delay.test = 120 -- do the same thing again but now after 120 ticks
end
end

In the PID function, the integral does not work properly. When the process variable is too high, the integral value gets stuck and stays the same unless the process value is changed

wouldnt the pid one potentially cause desync in multiplayers ? Since the global object "pid" would end up existing at different time depending on when a player entered the area
