Sorry, but i can’t find the error:

the text “win” dosen’t appears in the output

Your runtime is at fault. You aren’t calling any function. Yiu just passed ‘hits’ table so nothing happens

#3

How can i do appear the text “win” in the output???

#4

Pass function to runtime performing raycast and then checking

#5

Can you write it, please???

#6

Esh…

[lua]

local circle
local sX
local sY
local eX
local eY

local function checkForHit(object, from_x, from_y, to_x, to_y)
local hits = physics.rayCast( from_x, from_y, to_x, to_y, “closest” )

if hits[1].object == object then
print (“You Win”)
end
end

Runtime:addEventListener( “enterFrame”, function() checkForHit(circle, sX, sY, eX, eY ) end)

[/lua]

Thanks!!! :smiley:

For future reference, if you could write a more meaningful title for the post.  ‘Helpppp!’ isn’t very searchable or when people do search they see the title and won’t look into the thread where useful information might be…

Thanks
