Drag & Drop minigame

[Mira1976]

Need some help/advice , I would like implement to our game "simple" minigame which consist of paper or photograph or map shattered to pieces and player have to put it together. I made basic set up like this :

Code: Select all

init python:
    def drag_placed(drags, drop):
        if not drop:
            return

        store.draggable = drags[0].drag_name
        store.droppable = drop.drag_name

        return True

define p = Character ("Petr")
label start ():

    scene pozadi

    p "Hmmmm, nějaké smetí"
    p "Co kdybych si s tím trochu pohrál ?"
    call screen mapa

return
label mapa ():
screen mapa:
    draggroup:
        drag:
            drag_name "mapa1"
            xpos 300
            ypos 500
            child "mapa1.png"
            draggable True
            droppable False
            dragged drag_placed
            drag_raise True
        drag:
            drag_name "mapa2"
            xpos 100
            ypos 500
            child "mapa2.png"
            draggable True
            droppable False
            dragged drag_placed
            drag_raise True
        drag:
            drag_name "mapa3"
            xpos 200
            ypos 500
            child "mapa3.png"
            draggable True
            droppable False
            dragged drag_placed
            drag_raise True


return
call  pokr
label pokr():

p" dfsdfsfsdfsdfsdfsdfsdf"
return

but there is lot of problems, it works but i dont know how to escpae or leave the screen with pieces and especialy how to check the pieces are in right places, how to check, player made it right.
Im sure im not first trying this type of puzzle, but i cant find solution, or i dont know how to ask google propperly.

To check if the pieces are in the right place you have to create a drag for every spot where a puzzle piece can land and give it a drag_name.

Code: Select all

# a puzzle piece
drag:
    drag_name "piece1"
    dragged obj_dragged
    draggable True
    droppable False

# a spot for a piece
drag:
    drag_name "spot1"
    draggable False
    droppable True

When you drag a piece and drop it on a puzzle spot, then first obj_dragged is called for that piece. Now you just have to check if the correct piece was dropped onto it. You will leave the screen when you return something other than None.

Code: Select all

def obj_dragged(drags, drop):
    if not drop:
        renpy.notify("You dropped it outside of the possible places.")
        # leave the screen
        return True
    # something was dropped onto spot1
    if drop.drag_name == "spot1"
        if drags[0].drag_name == "piece1":
            renpy.notify("Correct piece!")
        else:
            renpy.notify("Wrong piece!")
    # this doesn't leave the screen
    return

[m_from_space]

P.S. You can snap the puzzle piece into the very correct position if it was dropped onto the right spot:

Code: Select all

if drags[0].drag_name == "piece1":
    # xpos, ypos, time for animation
    drags[0].snap(100, 100, 3.0)
    renpy.notify("Correct piece!")
else:
    renpy.notify("Wrong piece!")

Does it mean i have to create something like grid for those shatters ?

Looks like a jigsaw puzzle

Thanks, jigsaw i have already seen, but those frameworks looks too complicated for me, third link looks usefull, thanks for help.

[Mira1976]

Now i´m totaly lost.....After seeing this lines of codes and examples i have no idea where all that if statements and returns goes...
Try to make it easier only with two possible spots and one moveable object, but it is mess ...

Code: Select all

init python:
    def drag_puzzle(drags, drop):

        if not drop:
            return True

        if drags[0].drag_name=="ctverec" and drop.drag_name=="ctverec_drag"

        return True
    else:
        return
        store.draggable = drags[0].drag_name
        store.droppable = drop.drag_name

        return

define p = Character ("Petr")
label start ():

    scene pozadi

    p "Hmmmm, nějaké smetí"
    p "Co kdybych si s tím trochu pohrál ?"
    call screen mapa

return
label mapa ():
screen mapa:
    draggroup:
        drag:
            drag_name "ctverec"
            xpos 300
            ypos 500
            child "ctverec_drag.png"
            draggable True
            droppable False
            dragged drag_puzzle
            drag_raise True
        drag:
            drag_name "kruh"
            xpos 100
            ypos 500
            child "kruh.png"
            draggable False
            droppable True
            dragged drag_puzzle
            drag_raise True
        drag:
            drag_name "ctverec"
            xpos 200
            ypos 500
            child "ctverec.png"
            draggable False
            droppable True
            dragged drag_puzzle
            drag_raise True
return

got this error, but im sure all that stuff is wrong...

Code: Select all

I'm sorry, but errors were detected in your script. Please correct the
errors listed below, and try again.


File "game/script.rpy", line 8: invalid syntax
        if drags[0].drag_name == "ctverec" and drop.drag_name == "ctverec_drag"

...Try to make it easier only with two possible spots and one moveable object, but it is mess ...

In screen 'mapa' the droppable object (the last one) should have drag_name 'ctverec_drag'.

In drag_puzzle function:
- if drags[0].drag_name=="ctverec" and drop.drag_name=="ctverec_drag" line should ends with the colon and next line (return) should be extra indented,

- in else block remove the first return otherwise values of 'draggable' and 'droppable' variables won't be stored (those lines won't be executed).

[Alex]

Now i´m totaly lost.....After seeing this lines of codes and examples i have no idea where all that if statements and returns goes...

If you call 'mapa' screen then 'return True' in 'drag_puzzle' function will end player's interactions with this screen (return from called screen) and 'return' will let player continue interactions with this screen, 'cause goal of interactions is not achieved yet.

[Mira1976]

Wow, it works. Some mistakes are still in code, I mean something about positions of objects, but i have no error messages. Great thanks for your effort.

[Mira1976]

Now it looks like

Code: Select all

init python:
    def drag_puzzle(drags, drop):
        if not drop:
            return
        store.draggable = drags[0].drag_name
        store.droppable = drop.drag_name

        if drop.drag_name == "ctverec":
           if drags[0].drag_name == "ctverec_drag":
              drags[0].snap(600, 500, 1.0)
              renpy.notify ("correct")
           else:
              renpy.notify ("wrong")



define p = Character ("Petr")
label start ():

    scene pozadi

    p "Hmmmm, nějaké smetí"
    p "Co kdybych si s tím trochu pohrál ?"
    call screen mapa

return

            child "ctverec_drag.png"
            draggable True
            droppable False
            dragged drag_puzzle
            drag_raise True
        drag:
            drag_name "kruh"
            xpos 100
            ypos 500
            child "kruh.png"
            draggable False
            droppable True
            dragged drag_puzzle
            drag_raise True
        drag:

            drag_raise True
return
label pokr:
    p "dfsdfsfsdfsdfsdfsdfsdf"

palyer can move with object "ctverec_drag" and when place it to spot "ctverec" he get notify correct.(ctverec means square)
Some problems is still there. I dont know how to imlpemet this all to game, how to continue, where to call another screen or label ?
And can instead of renpy.notify my character comment what is going on ? Like " Yes i placed it right" ?
And im affraid i will not be able use this way for more pieces/shatters...

Ok im feeling like you have thought: " Jesus i have to write it for this idiot form A to Z "....
and i appreciate it and if i will not be able to finish what i want to make with this example, then i dont finish it ever.
Thank you very much.
