Help me, I want to find both A and B then click C

Is this correct?

----- created by AnkuLua snap and play script ------
immersive = true
setImmersiveMode(immersive)
genVersion = "8.8.0-pro2"
setAutoGameArea = true
pcall (autoGameArea, setAutoGameArea)
scriptDimension = 720
Settings:setScriptDimension(true, scriptDimension)
Settings:setCompareDimension(true, scriptDimension)
local index = 1
touchList = {}
waitList = {}

while (true) do
   if (exists("targetA.png") and exists("targetB.png")) then
       local loc = exists("targetC.png", 0)
       if (loc) then
           for i = 1, 10 do
               touchDown(loc)
wait(0.09)
               touchUp(loc)
           end
       end
   end
end



You should share the screenshots and the images.

while (true) do
if (exists("1.png") and exists("2.png")) then
local loc = click(Location(524, 1186))
if (loc) then
for i = 1, 50 do
touchDown(loc)
wait(0.01)
touchUp(loc)
end
end
end
end

From the above scripts that you gave me, It's work now.
And I want its to click at the marked location, so I'd change the scripts to these "local loc = click(Location(524, 1186))" but it's error.
Did I do something wrong? Which API to use with this? Thank you.
