SCRIPT DOESN’T EXECUTE AS INTENDED USING GUI.ANIMATE()
No errors today to use in the heading.
This is going to be something stupid, I know it.
I’ve written a game object to display instructions and controls at the beginning of every level via a series of sprites and animations. It may be skipped as well as accessed through the pause menu.
It doesn’t work. It pauses the game while nothing happens until you pause and unpause it yourself.
There is a sequencing I’ve had in mind when designing it:
-
proxy_manager loads the level
- all game objects initiate
-
level_manager sends a "pause" message to everything and a "start" message to the intro gui (called starter_gui)
- the
starter_gui runs through 5 animation functions and a countdown timer or until being skipped and sends a resume message to the level_manager
- the game proceeds as intended
Using debugging pprint() functions, the desired log ought to look a bit like:

Normally I’d currate the code to be readable on the blog, but honestly I have no idea what messes up, and I’ve been banging my head at this for a few days so…

while we’re at it, the level_manager also fails to reset positions of game objects in the function reset_positions(self) and I do not understand why. Is there any limitations or quirks on manipulating other objects’ positions?
function reset_positions(self)
for i, t in pairs(self.positions) do
go.set_position(t, self.objects[i])
end
print("Reset all objects' positions in P0N6")
end
If anyone has the time, will and ability to check the code for why it doesn’t work (other than poor coding practices and ‘it’s bad’) I would greatly appreciate. This is I thikn the last task I want to complete before moving on to building new world collections and mini-games.
