This one is driving me crazy. Maybe I’ve mixed up something with the syntax.
Basically, I have a series of sprites I want to move using Runtime and :translate(), like this:
[code]for i = 1, people.numChildren do
local moveX, moveY
local speed = 2
local nextpoint = waypoint + 1 – waypoints are x/y info stored in a table.
– figure out where to move along X, if any
if people[i].x == waypoints[nextpoint].x then
moveX = 0
else if people[i].x > waypoints[nextpoint].x then
moveX = -speed
else if people[i].x < waypoints[nextpoint].x then
moveX = speed
end
– Increment waypoint if necessary
if moveX == 0 then
waypoint = waypoint + 1
else
people[i]:translate(moveX,0)
end
end
Runtime:addEventListener(“enterFrame”, theFunctionthatdoesthestuffabove)
[/code]
Seems clean. Works perfectly. But if I add a -1 to the for loop…
for i = 1, people.numChildren, -1 doThe first person moves to somewhere between 40 and 50 px, stops, and that’s it, the whole for loop is over as if I hit an assert. Even though the for loop is set to take place on enterFrame, the function is firing but the for loop is not.
Case in point, add a print statement immediately after the for loop:
for i = 1, shoppers.numChildren, -1 do
print("The reverse for loop is working!")
end
…and the print statement ceases exactly as the character does.
Am I using reverse loops the wrong way? [import]uid: 41884 topic_id: 24520 reply_id: 324520[/import]
