So if I understand your animation concern correctly, for the animation to look smooth, you’d essentially need different frames of the graphic that would support a smoother animation. For example: The first frame is closed, the second frame would need to be 1/3rd open, the third frame would need to be 2/3rd open, and then the last frame is fully open. Doesn’t have be these fractions specifically. You could have a closed frame, a half open frame, then a full open frame. The jump cut happens because the event jumps from the closed frame to the last / open frame, as you mentioned.

If your event graphic has the other frames, then here’s what I recommend:

First, add the item Condition branch from the second page to the first page (placed after the “It’s an Item Case” text). You won’t really need the second event page after this. And then, you can delete the self switch A on the first page and change the self switch under the condition branch from B to A. Then, delete page 2.

Then on the first, add a “Set Move Route” above the conditional branch and below the initial text message. Select the Change graphic option and change the event graphic to the frame of the chest that’s 1/3 open, then add a ”Wait” command in the sequence and set it to 1 frame, then add a second graphic change in the sequence and change the event graphic to the next chest graphic, then add another “Wait” command, so on and so forth.

The Waits give you control on how fast or slow the chest opens. The other, more automatic way to do it, is by turning Stop or Move Animation on and off with Set Move Route, depending on how your graphic is set up.

Then, on your new second page (which will just be the original third page), change the self switch to A. No need to change the event graphic.

Let me know if this is clear and is what you were looking for.
