[solved / fixed] Drag & Drop Overlap and Snap Function

[m_from_space]

Hello,

I played around with the Drag & Drop feature of Ren'py.
https://www.renpy.org/dev-doc/html/drag_drop.html

Consider some kind of basketball situation with a (draggable) Drag called "drag_ball" that you can drag around, and there is also a (droppable) Drag called "drop_net" where you can drop the ball into.

Code: Select all

drag:
	child "ball" # the image of the ball
	drag_name "drag_ball"
	draggable True
	droppable False
	dragged obj_dragged
	
drag:
	child "net" # the image of the net
	drag_name "drop_net"
	draggable False
	droppable True

Now it is easy to just drop the ball into the net following the Ren'py documentation. And it is also possible to let the "ball" snap to the bottom of the screen - using the Drag.snap function - if it was not directly put into the net, I figured that one out.

Code: Select all

def obj_dragged(drags, drop):
	# the drag was not dropped onto a droppable drag
	if not drop:
		if drags[0].drag_name == "drag_ball":
			# let the ball snap to the bottom of the screen within 1.0 seconds
                	drags[0].snap(drags[0].x, 600, 1.0)
        # the drag was dropped onto a droppable drag
        else:
                if drop.drag_name == "drop_net":
                # we hit the net
                    return True
        return

But now I have some questions:

1) Is it possible to trigger that the ball overlaps the net while snapping to the bottom of the screen when the player did release it above the net? I actually want the ball to fall down and when it is overlapping the net, a function should trigger.

2) Is it possible to trigger when the Drag.snap() function ended its animation of 1 seconds before the script moves on? (This would be a workaround for question 1 if the ball is at a certain position.)

3) I really don't understand what the drop_allowable function is doing. Can you help me?

Thank you!

I solved this problem differently, so no need to answer here.
