Add animation playback preview to scene import settings #76367

Chaosus · 2023-04-23T12:15:39Z

This QoL enhancement will add the option to preview animations in the import settings window (to preview animations without performing extra actions such placing the models to a scene):

Not sure how hard it would be to implement, but could you add an option to show the bones when rendering an animation?

I am considering to import all my animations from seperate gltf files, so I wouldn't have a mesh for preview purposes during the import.

I compared #76367 and #76381, both have good and not good points.

#76367 has a seek bar. It is good that you can check the playback position with it. However, the negative is that the loop option is not linked to the import option for the preview. Since users may complain after importing that it is not in the same state as the preview, they should be linked.

#76381 does not have a seek bar, but it is preferable that the loop option for preview be linked to the import option. However, I recommend #76367 for animation because #76367 is more valuable for QOL since it has a seek bar.

BTW, the light settings for preview in #76381 are useful. So it is better to omit the animation feature and brush up #76381 for the preview environment option.

@TokageItLab I've updated this PR, and now when you click on animation in the list - it will auto-switch the loop button to enabled state (when loop mode is enabled in the animation) and will use play_backward if ping-pong is enabled at the animation end.

I don't think I need to add something more complex like default lightning or bone rendering (which is done by #76818)

TokageItLab · 2023-05-25T11:26:15Z

@Chaosus I understand that those are not necessary for this PR. But I think they can be implemented separately from this PR.

Below are the current problems with this PR:

The loop button in the GUI seems to do nothing, so please get rid of it. Or make sure it is correctly linked to the import option.

Also, for ping-pong, it should play to the end, then reverse, and then play forward when it gets to the beginning again. Please refer to the behavior of AnimationPlayer or #76381 for more example on this.

I am also concerned about the presence of gaps at the beginning and end of the seek bar. I don't know if it is a drawing issue or if it is not actually processing the animation, but can it be remedied?

sorry, the light settings video sample got mixed up with #76140 but they're a different PR

OK, I deleted it, it was working - but only after you press the play button manually.

Also, for ping-pong, it should play to the end, then reverse, and then play forward when it gets to the beginning again.

It's already being working, as you said. Isn't it?

I am also concerned about the presence of gaps at the beginning and end of the seek bar.

Not sure if I understand how to fix this...

No. It is always looped in the backward.

Chaosus · 2023-06-12T16:14:39Z

No. It is always looped in the backward.

OK, Fixed, now. Check again.

TokageItLab · 2023-06-12T17:41:32Z

I have confirmed that it has been fixed.

The remaining problem is that when you change the loop mode, you will need to update the ImportScene or animation for the preview. The current behavior does not update the loop settings until you open the PostImporter again after changing the loop mode and reimport.

Chaosus · 2023-06-13T05:37:06Z

@TokageItLab I think I fixed this, check again.

editor/import/scene_import_settings.cpp

+	switch (loop_mode) {
+		case Animation::LOOP_NONE: {
+			animation_play_button->set_icon(get_theme_icon(SNAME("MainPlay"), SNAME("EditorIcons")));
+			animation_slider->set_value_no_signal(1.0);
+			set_process(false);
+		} break;
+		case Animation::LOOP_LINEAR: {
+			animation_player->play(p_name);
+		} break;
+		case Animation::LOOP_PINGPONG: {
+			if (animation_pingpong) {
+				animation_player->play(p_name);
+			} else {
+				animation_player->play_backwards(p_name);
+			}
+			animation_pingpong = !animation_pingpong;
+		} break;
+		default: {
+		} break;
+	}


It seems a bit redundant to have to write the processing for looping outside of the AnimationPlayer, but I think this is the only way to do it for now. I will consider providing a better API in a future refactoring planned as godotengine/godot-proposals#5972.

I like the design. Did not technical review.
