Official PyGG2 Development thread

[Orpheon]

Anyone want to point me towards something they want done? I'm learning python, but I'm not far enough into the mindset to just start doing things.

Umm, well...

-You can improve anything you see in the code which is buggy (collision code for example)
-You could try making other classes and a class-select screen
-You could try making weapons (Scattergun+Shot object)
-You could try making menus, atm it jumps right into the game
-You could try to make a map background separate from the foreground, and maybe do the wallmask loading from a string like it's in gg2.
-You could try making health and HUDs
-You could try to make a game mode, probably ctf first.
-You could go learn how Twisted works for later, because we'll probably be using that for the networking.

Only suggestions though.

Against all odds, it works. We have a collision response code.
(even though it's a bit buggy at times)

Code:

def objectCheckCollision(character):

# Check if an object has hit the wallmask:

hasCollided = False

character.rect.centerx = character.x-character.xRectOffset
character.rect.centery = character.y-character.yRectOffset

clip = character.rect.clip(character.root.map.rect)

#find where clip's top-left point is in both rectangles
x1 = clip.left - character.root.map.rect.left
y1 = clip.top  - character.root.map.rect.top
 
#cycle through clip's area of the hitmasks
for x in range(clip.width):
for y in range(clip.height):
#returns True if neither pixel is blank
if character.root.map.mask.get_at((x1+x, y1+y)) == 1:
hasCollided = True

if hasCollided:
return True
else:
return False



def characterHitObstacle(character):


# THIS IS THE NEW VERSION; STILL WITH x/y


    newX = character.x
    newY = character.y

    hspeed = character.hspeed
    vspeed = character.vspeed

    length = lengthdir(hspeed, vspeed)

    if length == 0:# You haven't moved; if this happens something went wrong

        print "You haven't moved, yet managed to collide with something."
        return False


    # hs and vs is the normalized vector of hspeed and vspeed.
    hs = character.hspeed/length
    vs = character.vspeed/length

    while True:
        if not objectCheckCollision(character):
            break

        character.x -= hs
        character.y -= vs

# return True

    # This is the left-over velocity.
    hs = hspeed
    vs = vspeed

# The character got pushed out, but now we need to let him move in the directions he's allowed to move.


    character.x += sign(hs)

    if not objectCheckCollision(character) and abs(hs) > 0:

        # There's still room to move on the left/right

        i = 1
        while i <= abs(hs) and not objectCheckCollision(character):

            character.x += sign(hs)
            i += 1
    else:

        # Stop horizontal movement
        character.hspeed = 0
        character.hs = 0


    if objectCheckCollision(character):
        character.x -= sign(hs)

    character.y += sign(vs)

    if not objectCheckCollision(character) and abs(vs) > 0:

        # There's still room to move on the left/right


        i = 1
        while i <= abs(vs) and not objectCheckCollision(character):

            character.y += sign(vs)
            i += 1

    else:
        # Stop vertical movement
        character.vspeed = 0
        character.vs = 0

    if objectCheckCollision(character):
        character.y -= sign(vs)

    return True

Cool.

Now STOP USING TABS DAMNIT. Set your editor to replace tabs with 4 spaces :/

Uhh...I did that.

Code:

Tab Width: 4
Insert spaces instead of the tabs: On

No you didn't, the code you pasted there has tabs not spaces

[Orpheon]

No you didn't, the code you pasted there has tabs not spaces

I still changed the options.

[notajf]

No you didn't, the code you pasted there has tabs not spaces

I still changed the options.

well, fix your code. maybe you confused tab width and tabs to spaces

[Orpheon]

No you didn't, the code you pasted there has tabs not spaces

I still changed the options.

well, fix your code. maybe you confused tab width and tabs to spaces

Or maybe you just read portions of code that I wrote before. :/

Look at the collision response.

well fix the old code, inconsistency is the issue here

Hey today was my first day of Programming class and we're going to learn Python a lot throughout the year

We learned loops, strings, Boolean objects (mostly did Pythonkara), functions/def?

I have a question, how do you know how how much indenting to do? Thats the only hard part so far.

I hope in 5 months or so to know enough to help you guys out with this.

How much indenting?

Official is half a tab, or 4(?) spaces.
Normally you can configure your IDE/Text editor to do it when you hit tab.


And for one lesson you already learned a lot. Keep going.

[notajf]

Identing is simple, you increase after a colon, and decrease at the end of the block.

PyGG2 v0.1.5;

-Fixed a few minor bugs of the collision code
-Added a weapon class, a scattergun class and a scattergun sprite
-Added a function "point_direction" (this took a while)
-Made a character turn to face the mouse

[Psychopath]

-Made a character turn to face the mouse

Don't forget that certain animations will require exceptions to that such as the eating and stabbing animations (and taunt animations if you want to prevent people from spinning around while taunting).

Exceptions can easily be added later. And yes, I want to be able to change direction while taunting.

Also, I'd be really happy if someone could make the gun point to the mouse.
I made the function point_direction, the problem is the rotating sprite of course grows, but this isn't compensated by the draw positions.

Could someone please do this?

[HUNT3R]

Code:

while not kara.treeFront():
  kara.move()
  break
while kara.treeFront():
  kara.putLeaf() and kara.move()
       

That's my code. I'll define it later.

The problem is when I execute it, the "ladybug" moves 1 space and stops. I want it to move forward when tree not in front and put leaf if tree in front.

later I'm going to try to turn right if tree in front.

Do you see any problems with this code guys? :/ I had a few problems with the "break" so I just increased the indent until it didn't give me a syntax error.

What is a syntax error anyway?

[notajf]

A syntax error means bad syntax: like grammar or puncutation.

[Orpheon]

"break" means "exit the while loop". Your code won't work like that.

Try:

Code:

while True:
    while no kara.treeFront():
        kara.move()

    kara.turnRight()
