我在lua中遇到了麻烦。
问题一: 每次我运行以下程序时,控制台都会告诉我:
预计在“本地”附近出现“结束”(在第 1 行关闭“功能”)
请注意我在所有大写注释中标记了有关错误的详细信息
function m11()
local inst = mc.mcGetInstance() -- controller instance
local gcodeLineNbr = mc.mcCntlGetGcodeLineNbr(inst) -- get current Gcode line number
local gcodeLineStr = mc.mcCntlGetGcodeLine(inst, gcodeLineNbr) -- get current Gcode line
function valFromLine(string, axis)
local startPoint = string.find(string, axis) + 1
local outputVal = ""
local isNum = true
while isNum do
local num = string.sub(string, startPoint, startPoint)
startPoint = startPoint + 1
if num ~= " " then
outputVal = outputVal .. num
else
isNum = false
end
end
outputVal = tonumber(outputVal)
end
return outputVal
--COMPILER HIGHLIGHTS FOLLOWING LINE AS LOCATION OF ERROR
local gcodeLocX = valFromLine(gcodeLineStr, "X")
local curLocX = mc.mcAxisGetPos(inst, 0) -- get current X axis value
local curLocY = mc.mcAxisGetPos(inst, 1) -- get current Y axis value
local curLocZ = mc.mcAxisGetPos(inst, 2) -- get current Z axis value
local curAngB = mc.mcAxisGetPos(inst, 4) -- get current C axis value
local curAngC = mc.mcAxisGetPos(inst, 5) -- get current C axis value
local toolOffset = mc.mcCntlGetToolOffset(inst, 2) -- get tool offset for axis Z
function rotateToolB()
local comHypot = toolOffset * math.sin(angle) -- get XY planar dist from C pivot to tool centre point
local compDestinX = comHypot * math.sin(math.rad(90) - curAxisC + curLocX
end
end
--END OF M11() FUNCTION SHOULD BE HERE
if (mc.mcInEditor() == 1) then
m11()
end
我不明白为什么它期望 m11() 这么早关闭。
问题二: 我在一个完全独立的文件中重写了 valFromLine(),我得到:
'eof' 预计在 'print' 附近
function valFromLine(string, axis)
local startPoint = string.find(string, axis) + 1
local outputVal = ""
local isNum = true
while isNum do
local num = string.sub(string, startPoint, startPoint)
startPoint = startPoint + 1
if num ~= " " then
outputVal = outputVal .. num
else
isNum = false
end
end
outputVal = tonumber(outputVal)
end
return outputVal
print(valFromLine("GO1 X254.348 Y1039.456 Z150.13 B90.23 C13 M11", "X"))
我计算了我的“结束”语句,在任何一个代码示例中都找不到它们的问题。在这一点上,我完全失去了想法,请帮忙。谢谢。
