question about lua source navigation

I'm just learning lua and I use vim to navigate some lua projects. I  use ctags to generate tags using a map:

map <F12>  <Esc>:!ctags -R .<CR>

but it rarely helps. When I want to jump to some function definition, it always errs. Then I checked the generated tag and it seems fine. So my question is just is there a better way to navigate lua project?(esp. jumping to function definition?)
