Alarms/Wait function? (SOLVED)

[Gmanicus]

Greetings everyone!

I’m wondering if there is an alarm function built in to Defold that I can call to wait for (x) seconds before moving on in the function. What I’m looking to do is display a caret for a second, hide it for a second, and then rinse and repeat.

This sounds like something you could do with a repeating timer. There are plenty of threads on the forum regarding it

Here is one using Native Extensions
https://forum.defold.com/t/defold-timer-the-native-timer-extension/6581/9

Here is one using a lua module

Execute a function on a repeating timer (SOLVED)

I have seen and used the timer module provided by britzl (thanks for that btw). Is there a similar module or modification that will make it repeatable? I have a particular moment function that I would like to put on repeat about every 2-5 seconds. Thanks.

Here is one of people discussing delaying a function call with go.animate as a workaround

Delay functions?

Hi @peterH! I see two things: You renamed “delay” to “wait”, but are still calling “delay(…)” The “hide(5)” calls the function immediately and returns the result of that function (which is nil). It’s not a reference to the function. If you compare it to @britzl’s example, you see that he passes in the function references, not the return values of the functions. I’m not sure what a good way of passing extra values would be in this case. Do you have a specific use case you are tryin…

@britzl also have a couple of modules on his repo
This one in the gem bag that is ludobits

and this one among his gists

If you want blinking animation, you may do something like this:

local CUSTOM_EASING = vector {
	0, 0, 0, 0, 0, 0, 0, 0,
	1, 1, 1, 1, 1, 1, 1, 1,
}
local WHITE = vmath.vector4(1, 1, 1, 1),
local TRANSPARENT_WHITE = vmath.vector4(1, 1, 1, 0)
...
self.caret = gui.get_node("...")
...
local function start_blinking()
	gui.set_color(self.caret, WHITE)
	gui.animate(self.caret, gui.PROP_COLOR, TRANSPARENT_WHITE, CUSTOM_EASING, 1, 0, nil, gui.PLAYBACK_LOOP_FORWARD)
end
local function stop_blinking()
	gui.cancel_animation(self.caret, gui.PROP_COLOR)
	gui.set_color(self.caret, TRANSPARENT_WHITE)
end

@dmitriy Thanks. I already implemented the Native Timer Extension from Mattias’s reply.

@Gmanicus

I already implemented the Native Timer Extension from Mattias’s reply.

Cool! Let me know if you run into any issues. The extension isn’t really battle tested in a proper project yet!

[Gmanicus]

@britzl So, fixed a problem and then this one showed up. Am I doing this wrong? I followed what I understood from your example.

Paste the whole script?

Remember that native extension support currently only exists for iOS, OSX and Android. Windows, Linux and HTML5 will be available before mid-May if everything goes according to plan.

[Gmanicus]

Ah, that would be the problem. I’m working on Windows support currently, but I thought I read somewhere that it ran on all of those. I’ll have to find another extension. Thanks.

Just to be 100% clear, he means that all Native Extensions only work on iOS, OSX, and Android right now. You can’t compile an extension for Windows, Linux, or HTML5. If you want to run it on Windows and don’t want to wait for a month or so you’ll need to use one of the other methods Mattias Hedberg linked.
