Godot in dock "Graph"

JazzClam

A while ago, I was watching some devlog and the developer showed a sort of "Graph" in the dock where there was an X and Y value, an integer would be used for the X value and there was a line for the Y value, depending on what the X value was, it would change the Y value accordingly. I'm trying to make a system wherein the health of an enemy would impact that enemy's damage. I've spent hours scrolling through videos and searching pages upon pages of documentation, but i can't seem to find anything like it. Is this some sort of plugin?

Thanks, JazzClam

(It seems i'm supposed to ask this as a question)

Are you talking about visual script? You can make a visual script when you create a new script file. However, to answer your question, that functionality, changing x and y values, could be easily done in GDScript or any language really. Just create getters and setters (setget) that will update one variable when another is updated. Or make the damage a function that gets calculated based on health.

I'm not sure, I've tried setget but i'm having trouble implementing it for piecewise functions, where say, health between 100 and 50 lowers the damage at a slower rate than health between 300 and 100. I'm sure it was in the dock though.

Here's the graph, or at least I think. It's in a Miziziziz episode. Thouest Thee episode 5, 3:57. They're called curves in the documentation.

I haven't tested this so not sure if it would work but have you tried something like export(Curve) var my_curve?

JazzClam

Yeah, so if it doesn't work I can explore alternate means, but with a quick glance it seems really helpful for my purposes. The documentation is nicely fleshed out fortunately.

Try this:

extends Node2D

export var curve_data : Curve

func _ready():
	print(get_value(0.2))
	print(get_value(0.5))
	print(get_value(0.8))
	
func get_value(input):
	return curve_data.interpolate(input)

Then you can adjust the curve in the inspector.
