DRAGRI enables you to specify whether a drag path is effective or not according to the specific scene for each frame.
For example, assume that two actions such as "Open the dishwasher door (action 1)" and "Pull out the basket from the inside (action 2)" are to be added as follows:
![]() |
![]() |
Open the door (action 1). | Pull out the basket from the inside (action 2). |
Unless the effective section is set, both drag paths for opening the door and for pulling out the basket from the inside are displayed at the same time.
This means that the basket can be pulled out from the inside even before the door is opened. This is not realistic.
To avoid this, you must ensure that the drag path for pulling out the basket is not displayed until the door is fully opened.
Conversely, when the basket is pulled out from the inside, you must disable the drag path for opening and closing the door.
The effective section for a drag path is set in the timeline window. A green band is displayed on the drag path layer. A frame with a green band indicates that a drag path is effective in the frame.
Let's use the above dishwasher as an example to explain how to set the effective section for a drag path.
This is the first frame. Only the drag path for opening the door is displayed, although door_open has a green band, pull_basket has no green band.
In other words, in this frame, only door_open is effective, and pull_basket is ineffective and thus the drag path will not be displayed.
The door starts to be opened. In this frame, only door_open is effective, and pull_basket remains ineffective.
The door has been opened. In this frame, both door_open and pull_basket have a green band.
At this time, both drag paths are effective.
In this frame, the door can be closed and the basket can be pulled out from the inside.
This is the first frame where the basket is pulled out. In this frame, both pull_basket and door_open still have a green band.
Both drag paths are displayed.
The basket is pulled out. In this frame, a green band disappears from open_door.
open_door becomes ineffective and the corresponding drag path will not be displayed.
The basket has been pulled out. In this frame, only pull_basket is effective.
Dragging the mouse right on a green band splits the effective section and moves the starting point of the effective section to the right.
If the current frame is outside the effective section (white area), the drag path becomes ineffective and the drag path will not be displayed nor operated on.
Dragging the mouse outside the effective section (white area) adds a new effective section.
Dragging the mouse at the starting point or the end point of the effective section can extend or reduce the effective section.
As has been explained above, dragging the mouse at the starting point or the end point of the effective section can reduce the section. If the width of the band becomes 0 or negative, the effective section is deleted.
To delete an effective section with a width of 1, drag the mouse right to extend the width and then drag the mouse back to the left.
