Event Target

Solar2D General Questions/Discussion

Hi People.

I am using some functions and each function have a (local t = event.target), but i have a function that i need to use the target of other function, it is possible to do? [import]uid: 26056 topic_id: 23216 reply_id: 323216[/import]

Can you assign the target of another function to a different variable to make this simple?

Eg, rather than t use t2 (just an example) and then refer to t and t2 in the function as needed? [import]uid: 52491 topic_id: 23216 reply_id: 92953[/import]

Hi peach, i am using somer like it:

local one = function()  
local t = event.target  
--code...  
end  
  
addEventListener(...)  
  
-- and now, on this function i need to use the target of the   
--function one and if a do this code on the function two (again   
--local t = event.target) it will detect the object that event   
--listener refer for the function two, and i need the objects   
--(targets) of the function one  
  
local two = function()  
local t = event.target  
--code...  
end  
  
addEventListener(...)

Can you show me a really simple exemple? because i am not understading the part of “refer t and t2 in the function” :confused:

You could pre-declare some variables at the top of the lua file which you could use to store each functions event.target.

For example…

--Declare two new variables here..  
local funcOneTarget  
local funcTwoTarget  
local one = function()  
 local t = event.target  
 --Then set the variable we made here..  
 funcOneTarget = t  
 --code...  
end  
   
addEventListener(...)  
local two = function()  
 local t = event.target  
 funcTwoTarget = t  
 --code...  
end  
   
addEventListener(...)

Then you should be able to access them outside the functions. Is that what you had in mind? [import]uid: 69826 topic_id: 23216 reply_id: 92992[/import]

Bare in mind a small detail though. On TandG’s example, if for example the “one” listener runs first, the target for the second listener is yet undefined. [import]uid: 61899 topic_id: 23216 reply_id: 92997[/import]

Thats a good point, i probably should have mentioned that. Thanks clueless. [import]uid: 69826 topic_id: 23216 reply_id: 93002[/import]
