How to simulate a button press in code?

alspacka

In my project settings/input map, I have an action called "LD1", which is mapped to the z key on the keyboard. How do I simulate that button being pressed, and then released, in code? Thanks!

func _input(event): if event.is_action_pressed("LD1"): print("z key pressed") elif event.is_action_released("LD1"): print("z key released")

You can simulate a button press/release from code using Input.action_press and Input.action_release. (I think. I haven’t actually either function before)

I marked this as an answer, but it actually didn't work. I tried this bit of code, which worked from one script but not from the one I want. Trying to figure out why:

var a = InputEventAction.new() a.action = "LD1" a.pressed = true Input.parse_input_event(a)

I think you just need to do this Input.action_press(“LD1”), but I’ll have to check tomorrow. I have never used either function before, so it will be a good chance to learn how it works (as there are times when its useful to press/release actions from code)

Edit: Sorry, I likely will not have time today. I’ll try to look at it soon!

Alright, I have a bit of working code, using Godot 3.0.2 on Windows (10):

if (Input.is_action_just_pressed("ui_select")): Input.action_press("Test_action") if (Input.is_action_just_released("ui_select")): Input.action_release("Test_action") "------------------------------------------------------------" " I have no idea why I chose T and D... D for delete, and T for text?" if (Input.is_action_pressed("Test_action")): self.text += "T"; if (Input.is_action_just_released("Test_action")): self.text += "D"

Note: I attached this to a label, which is where self.text comes from. The one thing I did note is you have to use Input.action_release or the action will never cease to be released (and T will be continually added).

Hmm, I'm not sure. I've had mixed success with making InputEvent objects when I was working on remapping stuff (though that was back in Godot 3 alpha 1). That is a interesting way of doing it though! I would not have thought about trying something like that for simulating input events from code :smile:

Thanks for the response @TwistedTwigleg, that looks like it will work. I figured out why the one code snippet was working in one script and not another, and it was completely, and embarrassingly, unrelated to my question. When I pressed the play button, I was running my default root node rather than the root node in the new scenetree that I was working in! I didn't realize that was the way GE works.
