Unable to raise stats or substract energy

[LiquidDarkness]

I've been searching everywhere, using most of nerdy vocabulary I know and came up with nothing. Like stated above, I can't raise stats but nor can I deduct energy when doing action. I thought I've followed the documents and every advice I found on the forum, but still:

Code: Select all

I'm sorry, but an uncaught exception occurred.

And the code looks like that:

Code: Select all

label park:

screen park

menu park_activities:
    "What would you like to do here?"
    "Go jogging! (-25 energy)":
        "That was some intense jogging session! Your strenght has increased by 5!"
        $us_strenght += 5
        $player_energy=-25
        jump park
    "Read some book (-25 energy)":
        "Reading is always profitable for the brain! Your knowledge has increased by 5!"
        $us_knowledge += 5
        $player_energy-=25
        jump park
    "Pick up the polluting trash! (-25 energy)":
        "You spend some time on cleaning the park! Your goodness has increased by 5!"
        $us_good += 5
        $player_energy-=25
        jump park
    "Nothing":
        jump tokyo_city

This stops me from doing literrally anything and I'm a total noob, as you can see, so please, go easy on me and explaaaain what do I do wrooong? （；へ：）

In case that's needed, here goes a part with the stats definition.

Code: Select all

define player_energy = "Energy"
define player_energy_min = 0
define player_energy_max = 100
if player_energy = 0:
    "You need to go to sleep, you have no energy left!"

default us_beauty = 5
default us_good = 7
default us_knowledge = 3
default us_strenght = 4
default us_beauty_max = 1000
default us_good_max = 1000
default us_knowledge_max = 1000
default us_strenght_max = 1000

Your error is pointed out in the traceback:
$player_energy=-25
This is the wrong way around.
The jogging action is where you slipped up. Change it to this (like your others)
$player_energy -= 25

[Remix]

define player_energy = "Energy"
...
ok, so player_energy is a string (unicode)
...
$ player_energy -= 25
...
unicode string minus 25 ... hmmm, error perhaps?

[LiquidDarkness]

Thank you for such a prompt reply! (　＾∇＾)

I still encounter the same error, though.

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/park.rpy", line 15, in script
    $player_energy -= 25
  File "game/park.rpy", line 15, in <module>
    $player_energy -= 25
TypeError: unsupported operand type(s) for -=: 'unicode' and 'int'

Is there any possibility that I have made a mistake somewhere else?

[HansBr]

Is player_energy still a string?
You can examine your variables before you make a menu choice with <shift>-D
Should be a number, not a string like "Energy".

[Imperf3kt]

As noticed by Remix, you have defined 'player_energy' as a string, but later edit it as if it were an integer.

To put it simpler, you have written:
Energy -25 where 'Energy' = 100
Instead of
100-25
And it is confusing Ren'Py. You cannot subtract 25 from 'Energy' because 'Energy' is a word, not a number.

Change your default player_energy to a numerical value.

[LiquidDarkness]

Ok, so I don't get the error screen anymore, which is good. (　＾∇＾)

But.
The energy level is supposed to get lower with the activities and it does not, neither do the stat raise.

[HansBr]

How do you determine that these variables do not change? Do you have them displayed anywhere?
Maybe it's just the display code that is constant.
Or do you check them in any other way?

[LiquidDarkness]

I gave the player a 100 energy points and each activity was supposed to take 25 energy points away, so after choosing any four times I should see an information that I've ran out of energy. And about the stats- I found a thread on the cookbook part of the forum about displaying stats in the easiest way, and that's the code:

Code: Select all

default stat_1 = us_good
default stat_2 = us_beauty
default stat_3 = us_strenght
default stat_4 = us_knowledge

screen control:
    frame:
        xalign 0.02
        yalign 0.02
        textbutton "Stat Box" action If(renpy.get_screen("stat_box"), Hide("stat_box"), Show("stat_box"))

screen stat_box:
    frame:
        align (0.5,0.5)
        vbox:
            text "Goodness: [stat_1]"
            text "Beauty: [stat_2]"
            text "Strenght: [stat_3]"
            text "Knowledge: [stat_4]"

My problem might seem ridiculous to the more advanced programmers, I'm aware of that, but the only reason I started the subject is because I couldn't find the answer elsewhere.

[LiquidDarkness]

I now know how to raise them stats, hurray. But the energy thingy remains a mystery to me.

[Imperf3kt]

Without limiting the energy to 0, you can continue to subtract from energy until you are well into the negatives.

A simple way to avoid this: (add to your menu choices)

Code: Select all

    if player_energy =>25: # may be >=
        $ player_energy -= 25
        # your action here
    else:
        "Damn, I'm beat. I haven't got the energy to do that right now."

[HansBr]

In your initial code snipped it seems to me you check the energy at the beginning of your code, then never again.
Try checking before you change, as Imperf3kt told, or if you want to check less often at an appropriate more central place. For example at the beginning or end of your park_activities block.

[LiquidDarkness]

Ok, so I've done that:

Code: Select all

    "What would you like to do here?"
    "Go jogging! (-25 energy)":
        if player_energy =>25: # may be >=
        $ player_energy -= 25
        "That was some intense jogging session! Your strenght has increased by 5!"
        $stat_3 += 5
        $player_energy -= 25
        jump park
    else:
        "Damn, I'm beat. I haven't got the energy to do that right now."
        jump park

and this happens:

Code: Select all

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


File "game/park.rpy", line 8: if statement expects a non-empty block.
    if player_energy =>25: 
                           ^

File "game/park.rpy", line 14: expected menuitem
    else:
    ^

[Imperf3kt]

You have some indentation mismatches.
Try this:

Code: Select all

    "What would you like to do here?"
    "Go jogging! (-25 energy)":
        if player_energy =>25:
            "That was some intense jogging session! Your strenght has increased by 5!"
            $stat_3 += 5
            $player_energy -= 25
            jump park
        else:
            "Damn, I'm beat. I haven't got the energy to do that right now."
            jump park
