shadow my understanding of tables is they give information about the chacacter(s), like health, weapons, ect...correct me if i'm wrong yaustar

[Shadowblind]

hmmm... would a standard table be

green = Color.new(19, 20, 21)
red = Color.new(22, 23, 24)
orange = Color.new(25, 26, 27)
yellow = Color.new(28, 29, 30)

yo dtothabreezy screen:blit(player.x,player.y,playerimage) what exactly does that do?

[dtothabreezy]

player .x is where your charcter is relative to x of the psp like a graph its the one that goes out y is the one that goes up if you were to minus or plus x it would give the illosion of movment ahhh you get it

playerimage is what i use so it will blit all of the images i want in what way i want like if i would want playerimage to be him walking when you press right it would say playerimage=walk or something like that in my new animation system it runs off functions but i still keep that as a defualt to make it easier

i don't think so, i mean i'm just lookin at the tuts at evilmana i used a different site before(shoulda use evilmana ) but i think thats just creating colour for the script to use, tables are used to store information about the character, like health, weapons, ammo, ect.

[dtothabreezy]

you could do something like that but you would be going out of your way to make that becuz most pepole just put those in at the top yall r the fastest posters ive seen in my life

o and so u know the colors when you put them in are like

the c in the color.new most be capatalized
color=Color.new(red,green,blue)
just remeber that so like to make green youd
green=Color.new(0,255,0) 255 is the most you can put in
dont worry itll come quickly after a while youll get yoused to it

[BL4Z3D247]

lol i know i do post fast

[BL4Z3D247]

shadow heres a table:

green = Color.new(0, 255, 0)
Enemy = { }
Enemy[1] = { type = "gargoyle", health = 100 }
Enemy[2] = { type = "vampire", health = 100 }
Enemy[3] = { type = "goomba", health = 100 }
Enemy[4] = { type = "ghost", health = 100 }
Enemy[5] = { type = "zombie", health = 100 }

Player = { }
Player[1] = { weapon = "sword", health = 100 }
Player[2] = { weapon = "knife", health = 100 }

while true do
pad = Controls.read()

screen:clear()

screenrint(5,10,"Player 1 Health: " .. Player[1].health,green)
screenrint(5,20,"Player 1 Weapon: " .. Player[1].weapon,green)

screenrint(250,10,"Enemy Health: " .. Enemy[1].health,green)
screenrint(250,20,"Enemy Type: " .. Enemy[1].type,green)

if pad:cross() then
Enemy[1].health = Enemy[1].health - 5
end

screen.waitVblankStart()
screen.flip()
end

oldpad = Controls.read()

if pad:cross() and oldpad:cross() ~= pad:cross() then

oldpad = pad

if pad:cross() and oldpad:cross() ~= pad:cross() and Enemy[1].health > 0 then

...thats right off of evilmana, i think this is concidered the tabels(arrays)

[yaustar]

I have a shot at explaining the concept of a table.
Think of a variable as a storage box. The box can be empty (nil) or it can have something in it. Eg, value, image, text etc.

Now a table is a stack of these boxes and you can refer to them as Box 1, Box 2 etc. You can remove or insert boxes into/out of this stack and you can refer the stack of boxes as a group under one name.

That's the concept, the syntax in Lua can be cofusing so I let the Wiki deal with that.
http://lua-users.org/wiki/TablesTutorial

Note that tables are also refered to as arrays in places.

Enemy = { }
Enemy[1] = { type = "gargoyle", health = 100 }
Enemy[2] = { type = "vampire", health = 100 }
Enemy[3] = { type = "goomba", health = 100 }
Enemy[4] = { type = "ghost", health = 100 }
Enemy[5] = { type = "zombie", health = 100 }

What you have done here is created a table called 'Enemy' and for each entry/storage box in 'Enemy' created another table that has two entries; 'type' and 'health'.

fg-54 is having this problem: He has script.lua and script.cmd in the same file, when he runs script.cmd it says no lua file in the directory. Whats wrong?

BTW, can you make a simple game using a table? Thats what evilmana wants me to do...

Therefore, I can open your code and see how its placed.
