Hey I'm just starting off in love working my way around lua

I'm very familiar when it comes to design scripting and creating games in other engines without a problem. I'm trying to figure out how to create a sprite/object to use as my player. a point the right direction would help me out a lot.

The simplest way would be to make a table (think of it as an object, in this case), let's call it "player", which stores the player's position, graphic, health, and whatnot.

Code: Select all

player.x = 100
player.y = 200
player.image = love.graphics.newImage("player.png")
player.health = 100

And then draw the player in your love.draw() function:

Code: Select all

function love.draw()
	love.graphics.draw( player.image, player.x, player.y, 0, 1, 1, 0, 0) )
end

And there you go - a player with a position, a graphic, and a health value. Add some code to love.update(dt) to make it move around, and you're off to a fine start.

ok cool now I got a movable little smiley face. how about animated sprites and please don't tell me gif images. I'm saying like either using 1 image like a tileset of images for the character with all their animations in it. if it's supported. or how to use multiple external images to create my animation.

I have theory for how it would work with multiple images.

something like

Code: Select all

EndFrame=10
Frame =0
Player.image = love.graphics.newImage("Face"+Frame+".png")

function love.update(dt)
Frame = Frame+1
if Frame > EndFrame Then
Frame =0
end
}

function love.draw()
	love.graphics.draw( Player.image, Player.x, Player.y, 3.14, 1, 1, 0, 0) 
end

and then have each frame of the animation like Face0.png, Face1.png and so on.

would that work or is there a better method?
don't mind my syntax I'm still learning Lua.

Lots of syntax errors indeed.

If I would write the exact thing you were trying to do, I would to it this way:

Code: Select all

function love.load()
    EndFrame=10
    Frame = 1
    Images = {}
    for i=1,EndFrame do
        Images[i] = love.graphics.newImage("Face"..i..".png") -- + doesn't work on strings
    end
    Player = {x = 300, y = 200}
end

function love.update(dt)
    Frame = Frame % EndFrame + 1
end

function love.draw()
   love.graphics.draw(Images[Frame], Player.x, Player.y, 3.14, 1, 1, 0, 0)
end

Disclaimer: completely untested, blablabla

oh ok so I did sort of have an idea how it would work. yes putting it in a array would make more since.

so adding variables to strings is kinda like php syntax.
