I don't think ANY luaplayer YET supports unzipping, That could be a feature 4 luaplayerHM in the future

[eldiablov]

As if it isnt bloated enough :/

:ROFL: true. I didn't ask though. I think Zip support is pretty useless.
I don't see myself ever needing to use it.

My question: Could i connect to a website. And download a file On that website, using the correct url.
eg http://www.watever.com/file.lua
And then could i download the new script to replace(overwrite) the new 1??

Or wait for PGELua

[dan369]

How Long until PGE??
I haven't seen IWN on in a while.

[TurtlesPwn]

Sooner than you probably think

Hey fellas,
well um I'm not sure if i can post here since I'm not really a "developer" but here goes.

I'm learning LUA and I have seen a few tutorials around via google and I stumbled upon the "Ultimate QJ Guide" which had a few tutorials but not what I am looking for.

Anyways, is there a tutorial on sprite animation? If not could someone just tell me the basics of sprite animation and i could fill in the rest.

It does not matter if its on multi images or sprite sheets

thanks in advance

Take a look here. :)

Thanks for the link Moose I appreciate it.
Its too bad I don't know how to use C, I will try and convert it but I am not sure if I will get this to work haha.

basically have a timer and have it display a different image at a certain time interval.

[TurtlesPwn]

No.
Have an integer counter, not a timer, counting, and display each image for an interval of that counter's range of counting, and then when it passes the last frame's range, reset to 0 and start over.

TurtlesPwn got to it.

I don't think that will work. I am trying to make it so when my character moves it animates with the movement. Could I use an if then statement saying that when it moves, lets say 2 pixels over to resume, wait 1, then pause?

HUH?? you want ur character 2 move just 2 pixels. then pause??
May i ask why??
Though its simple, using animLib or timers 4 animation.

[wicked_fable]

Okay, my post that I erased had to do with your problem. So apparently I did not need to erase ti.

Depending on what you want to do, there are different methods for animation. In your case, you want to make the character move and animate at the same time so it looks like he is walking. The simplest way to do this would be to have two frames for each movement. That is a walking and standing frame for going North, South, East, and West.

Now, if you have this, good, but if you have more than just two frames for each direction i suggestion you cut it down to just two for now that way you can learn the basics. I will not be posting any code that way you can figure out how to code it yourself and therefore understand it better but I will give you the concept.

When you make the character move you want it to change its frame to a walking frame then when it moves again it should change back to a standing frame. These two frames combined make it look like its legs are actually moving and walking. So, in order to do this, you should basically make it so that when your sprite walks it displays frame 1. If it walks again and frame 1 is showing it should display frame 2. In this way it will alternate between frame 1 and frame 2 so that it looks like it is walking.

I highly recommend you try to figure out the code for yourself as it will igve you a better learning experience than if you had someone show you exactly how it works.

THe best advice, You also get a sense of achievement lol

Heh, yup. I spent a few days working on this alone before I finally got it just right and boy did it feel so cool to see a little man walking across the screen.

[tre_flip]

ok i am working an old code which i used to simply move a sprite around ill PM you wicked, with my sample code

[corytheidiot1]

I need help with getting luaplayerhm7 to download a txt file from my site. And depending upon what information is in that txt file I need it to be able to download a zip file from my site. They will both be stored in the root of my site, e.g. www.mysite.com/(files i need here). A bit of code i could use would help greatly.

hey guys i cant text my script but i think this will work for sprite animation

if pad:left() and Player1[1].x > 0 and Player == Player[1]
then Player1[1].x = Player1[1].x - 2 and screen:blit(Player[1].x,Player[1].y,player2)
end

[dan369]

Nope, ur saying if left is pressed and the player's X is over 0 and the Player == Player[1] --- i'm persuming this is a table then move the player. then blit the Image every time left is pressed which is not needed.
-=Double Post Merge =-
All u need 4 VERY SIMPLE animation is a variable and a function theres a clue 4 u.
Sry bout the double post.

[tre_flip]

its not finished but i will add more to it making it basicaly alternate between player1 and player2
and yes that was a table

BUT
will it work? idc if its not needed it works right?

[dan369]

It don't think it will work.
example:

timer = 0

function moveL()
timer = timer + 1

if timer == 2 then
change img
elseif timer == 4 then 
change img
      end
end

[tre_flip]

It don't think it will work.
example:

timer = 0

function moveL()
timer = timer + 1

if timer == 2 then
change img
elseif timer == 4 then 
change img
      end
end

alright ill check out your thing but dont you definitely need a command to reset the timer back to 0?

[dan369]

yep, but i didnt want to give the code on a plate 2 u.
U can do that urself.

[tre_flip]

haha i thought you were trying to test me

[dan369]

I shows basic Logic. U've passed Test 1 LOL
also don't re-use that variable more than 4 times. Otherwise..........,,.. the animation messes up.

[tre_flip]

dont re use the timer reset variable 4 times?

[dan369]

Forgot That. Have a drifferent timer 4 each animation, e.g timer2 = 0, timer3 = 0 etc.
