how to catch exception,error in Gideros

louis

I try to use pcall(function()end) and assertion(fucntion() end) in lua code, but program still crashed.
my question is how to catch exception in app ,if has I catch error,app can still work,not print stack trace on console and app crashed.

I think you need to give more information. For example here is a simple example code snippet:

local function crash() a[1] = 10 end   local status, err = pcall(crash)   print(status, err)

btw, does your program crash or give lua error?

sorry ,my fault.

local function crash() assert(nil,"crash error") end   local status, err = pcall(crash)   print(status, err)

@louis,
I think the whole idea of assert is to crash if the condition was not met, assert cannot be masked even if used with pcall.
