I am using function waitClick
How I can handle exception when image is not present?
I want to know when image is not present, so I run another code.

if (not existsClick("target.png")) then
....
end

Just use existsClick() if (not existsClick("target.png")) then .... end Friend, I must use waitClick function, so I will know if code will find this image. For example in pseudocode: try waitClick("image.png") catch exception: -- image not found! Running another function! end
Some other code, that is running after image is found, or after exception is handled.
Is there any way to catch exceptions in ankulua?

Just use existsClick() if (not existsClick("target.png")) then .... end Can I run existsClick with timer, for example 5 seconds? existsClick("target.png",5) then ... end ? I am asking, because I can't find documentation that I can read. |

Thank you friend. Is there also goto function? I want fast go to start of the program. I know that using goto is not a good practice, but it will save me time.  |

No. goto is not supported.

Ankulua, I think the poster of this thread actually has a point- I have code which is like this If exists("a.png") then Dragdrop("a.png", location) End However during the time taken to find if a exists, it disappears from screen leading to the script ending, and me being very cross at my code. Any advice? Edit: found out way to fix from Lua docs, posting link and example below to help other users  |

Function battle()
Click("test.png") --Badly coded on purpose, no test.png on screen, so returns error
End
if not(pcall(battle)) then
Toast("error occured- ignoring")
--If an error occured during battle function
end

I tried to use pcall, but I failed, and I thought that pcall not exists in akulua. What means: Toast("error occured- ignoring") What Toast displays? |

I tried to use pcall, but I failed, and I thought that pcall not exists in akulua. What means: Toast("error occured- ignoring") What Toast displays? Pcall works in ankulua. It calls a function in protected mode (see example). Toast displays a notification to the user which displays for about 1 second |
