Point and Click Sample Project

This is a simple game to demonstrate:
- the use of an inventory screen that uses Screen Language per KimiYoriBaka (see
http://lemmasoft.renai.us/forums/viewto ... =8&t=12849)
- the use of Screen Language to create a point and click style puzzle.
Each room gets its own screen that looks like this:
Code: Select all
screen outside_room:
on "hide" action Hide("displayTextScreen")
if iFirewood not in inventory and not fireplace_wood:
add "outside_wood.jpg"
imagebutton:
xpos 370
ypos 462
xanchor 0.5
yanchor 0.5
idle "empty.png"
hover "yellow.png"
action [Hide("displayTextScreen"),addItem(iFirewood)]
hovered Show("displayTextScreen", displayText = "Someone left some wood here.")
unhovered Hide("displayTextScreen")
else:
add "outside.jpg"
imagebutton:
xanchor 0.5
yanchor 0.5
xpos 650
ypos 322
idle "empty.png"
hover "yellow.png"
action Jump("kitchen")
hovered Show("displayTextScreen", displayText = "Go to Kitchen.")
unhovered Hide("displayTextScreen")
Something I did was change the whole background when someone picked something up. That's because I was being lazy and just using the 3d renders.
The fish was done differently:
Code: Select all
if iFish not in inventory:
add "herring.png" xpos 500 ypos 160 xanchor 0.5 yanchor 0.5
imagebutton:
xanchor 0.5
yanchor 0.5
xpos 500
ypos 160
idle "empty.png"
hover "yellow.png"
action [Hide("displayTextScreen"),addItem(iFish)]
hovered Show("displayTextScreen", displayText = "Someone left this fish out.")
unhovered Hide("displayTextScreen")
I could have just used the fish image for the imagebutton, but I wanted to stay consistent with the yellow circle.
Items are defined like this:
Item(name,imagename)
Example:
Code: Select all
iMatch = Item("Match","match.png")
iFirewood = Item("Firewood","wood.png")
iFish = Item("Fish","herring_item.png")
I made a couple of Screen Actions to help me out.
addItem: Action that adds the item to the player's inventory
addItem(item)
example:
Code: Select all
if iFish not in inventory:
imagebutton:
idle "herring.png"
hover "herring_hover.png"
action addItem(iFish)
: Action that will test to see if the selected item is a certain item, then change a variable, then optionally remove the item
testItem(item,variable, value, remove)
Code: Select all
imagebutton:
idle "empty.png"
hover "yellow.png"
action testItem(iFirewood,"fireplace_wood", True, True)
That test to see if the iFirewood item is selected. If it is, then fireplace_wood is set to True and the item is removed from inventory.
I think it is pretty self explanatory; but then again, I wrote it.
Now to see if it works on Android.

Download the attached file (PointandClickTest.zip) and unzip it into your Ren'py Files directory to see the code.

it's interesting that you posted this just as I was considering whether to post code for changing the mouse cursor at any time (which I just got working a couple days ago).
a few criticisms:
--it'd be better to put the text describing the objects at the bottom or top of the screen so that it doesn't get in the way of everything else.
--it's really not a good idea to have the player click arbitrary spots to change locations.

That would be cool.

I was debating whether the text would be better in the one location, or if near the cursor like a tooltip would be better.
About the changing location hotspots, I put those in at the last minute. Previously I was using menu items. In an actual game, would it be better to have exits in the graphic (such as the doors) just by themselves; or also have arrows that indicate movement?

depends on the game's atmosphere. in this case, either would work as long as the player doesn't have to search for them

The source code is included with the game for

Windows-XP-5.1.2600-SP3
Ren'Py 6.17.4.409
trial 0.0
It only happen when the spot is clicked without the selected item. (when it supposed to be ignored??)
I just want to know what is wrong and how to fix it but I'm so noob when it comes to coding ; u ;
also I'm using Ren'Py 6.17.4.409 (but planning to use the newer version; 6.18.3)

Unfortunately I am current in a chemotherapy induced brain fog and am unable to help.
Could someone else could look into this?

shortycake: Just tested it and it works for me on 6.18.3. Are you testing it on your own project or are you playing the sample game?
SusanTheCat: I hope you get well soon.

SusanTheCat: Oh, I'm so sorry for bothering you, I hope you'll get better soon.
DragoonHP: Hi. Thank you for replying to me. Yes, I'm testing it in my own project (new project) and in sample game it works perfectly fine. I tried to copy-paste them all into a new project and it works fine as long I don't edit much the script DX

It looks like you are forgetting something in the code. The error means that there is no variable named active_item.
Can you share the code if you don't mind? (Also, is there a line "$ active_state = None" under label start)

Hey Susan the Cat, I have just played your point and click, and it is such wonderful example I have been looking around for! Hope you are doing well and have recovered, or on your way to full recovery.
Thank you!

Very nice tutorial! I created a tutorial in case anyone had trouble understanding the ImageButton.
