Switch (time reverse)

[alexgross]

Hi everyone!
Please tell me how can i make a countdown switch by clicking a checkbox, i.e. I made a tree of nodes: text (added a time code modifier) ​​-> timespeed -> transform. For time speed, I set -1 or 1 to change the counting direction (thanks for the hint @mrjholt), in the Transform node in the tab, the user made a checkbox (time reverse).
I tried to create an expression in the time speed node, but there is no way to add an expression by pressing the right mouse button.

1. is it possible to make a check box that would change the direction of the time code?
2. can you know another option?

Thanks)

Code: Select all

{
	Tools = ordered() {
		Text3 = TextPlus {
			NameSet = true,
			Inputs = {
				GlobalOut = Input { Value = 149, },
				Width = Input { Value = 1920, },
				Height = Input { Value = 1080, },
				["Gamut.SLogVersion"] = Input { Value = FuID { "SLog2" }, },
				StyledText = Input {
					SourceOp = "TimeCode1_1",
					Source = "Time",
				},
				Font = Input { Value = "Open Sans", },
				Style = Input { Value = "Regular", },
				Size = Input { Value = 0.0949, },
				VerticalJustificationNew = Input { Value = 3, },
				HorizontalJustificationNew = Input { Value = 3, },
				ManualFontKerningPlacement = Input {
					Value = StyledText {
						Array = {
						},
						Value = ""
					},
				},
			},
			ViewInfo = OperatorInfo { Pos = { 880, 82.5 } },
		},
		TimeCode1_1 = TimeCode {
			CtrlWZoom = false,
			Inputs = {
				DropFrame = Input { Value = 0, },
			},
		},
		TimeSpeed1_1 = TimeSpeed {
			Inputs = {
				Input = Input {
					SourceOp = "Text3",
					Source = "Output",
				},
			},
			ViewInfo = OperatorInfo { Pos = { 880, 115.5 } },
		},
		Transform1_2_12 = Transform {
			Inputs = {
				Input = Input {
					SourceOp = "TimeSpeed1_1",
					Source = "Output",
				},
			},
			ViewInfo = OperatorInfo { Pos = { 880, 148.5 } },
			UserControls = ordered() {
				TimeRevers = {
					LINKS_Name = "TimeRevers",
					LINKID_DataType = "Number",
					INPID_InputControl = "CheckboxControl",
					INP_Integer = false,
					CBC_TriState = false,
				}
			}
		}
	}
}

You'll need to use the Edit Controls dialog to add the Animatable property to the Speed control.



However, there's a reason that TimeSpeed is not usually animatable. If you try to set a keyframe on it, you won't get a sequence that reverses direction at the time the keyframe is set. It will instead behave as though the control had always had that value. In other words, if you have a sequence from frames 1 - 10, running forward to frame 3, then the Reverse switch is thrown, your frame count will be 1, 2, 3, 7, 6, 5, 4.

The answer was, as always, very simple. with the help of the disolve node, it was possible to implement what I needed.
