Warping screen? [RESOLVED]

[Evil_Bartek]

This is my main.lua so far...

Code: Select all

function love.load()
    char = {posx = 40,posy = 160,width = 40, length = 40, health = 100}
end

function love.draw()
    love.graphics.rectangle("fill",char.posx,char.posy,char.width,char.length)
end

-- Don't change this, I like it that way ~Evil_Bartek 

function love.update(dt)
    if love.keyboard.isDown("right") then
        char.posx = char.posx + 0.4
	elseif love.keyboard.isDown("left") then
        char.posx = char.posx - 0.4 
    end
end

Just some noob code i wrote, you can see what it does...

How can i make it so when hes out of screen in a horizontal position. Like if he went out of the right or left side of the screen, how can i make him appear on the other side?

EDIT: I did make a conf.lua but thats not needed here...

you can do something like this:

Code: Select all

function love.update(dt)
    if love.keyboard.isDown("right") then
        char.posx = char.posx + 0.4
   elseif love.keyboard.isDown("left") then
        char.posx = char.posx - 0.4 
    end


	local width = love.graphics.getWidth()
	local height = love.graphics.getHeight()
	
	if char.posx <= 0 then -- if the character "x" is equal less than "0" meaning it's outside the left side of the screen
	char.posx = width - char.width -- set the character "x" to the width of the screen minus the character width, so he appears on the right side

	elseif char.posx >= width - char.width then
	char.posx = width - width
	end
	

end

basically "love.graphics.getWidth, and getHeight" will grab the width and height of the screen. Using this you can just use some simple "if" statements to teleport the player if they go beyond the sides of the screen.

so this code is saying "if the characters "x" is less than the screen's x, then that means the character is going past the left side of the screen", and "if the characters "x" is MORE than the screen width then the character is going past the right side of the screen"

then you're just setting a new character.x, and character.y depending on what's happening.

It works but it's kinda fishy.

It looks like its teleporting.
Can you make its so that if you go out of screen on the right it will only teleport if the left edge touches it?
Is that possible?

I FIXED IT SO ITS BETTER:

Code: Select all

function love.load()
    require "conf.lua"
    char = {posx = 40,posy = 160,width = 40, length = 40, health = 100}
end

function love.draw()
    love.graphics.rectangle("fill",char.posx,char.posy,char.width,char.length)
end

function love.update(dt)
    if love.keyboard.isDown("right") then
        char.posx = char.posx + 0.4
	elseif love.keyboard.isDown("left") then
        char.posx = char.posx - 0.4 
    end
	

   local width = love.graphics.getWidth()
   local lol = width + 40
   local height = love.graphics.getHeight()
   
   if char.posx <= -40 then
   char.posx = width - char.width
   elseif char.posx >= lol - char.width then
   char.posx = width - width
   end
end

Thatk you for the general template anyway, i improved your karma.

By "warp" I assumed you meant teleport. Also yeah, you can just do the same thing as I did with the opposite side. Just "- character.w".

Great!

EVEN BETTER:

Code: Select all

function love.load()
    require "conf.lua"
    char = {posx = 40,posy = 160,width = 40, length = 40, health = 100}
end

function love.draw()
    love.graphics.rectangle("fill",char.posx,char.posy,char.width,char.length)
end

function love.update(dt)
    if love.keyboard.isDown("right") then
        char.posx = char.posx + 0.4
	elseif love.keyboard.isDown("left") then
        char.posx = char.posx - 0.4 
    end
	

   local width = love.graphics.getWidth()
   local height = love.graphics.getHeight()
   
   if char.posx <= -40 then
   char.posx = (width + 35) - char.width
   elseif char.posx >= (width + char.width) - char.width then
   char.posx = (width - 35) - width
   end
end

Its ass smooth as it could be...

EVEN BETTER:

function love.load()
    require "conf.lua"
    char = {posx = 40,posy = 160,width = 40, length = 40, health = 100}
end

function love.draw()
    love.graphics.rectangle("fill",char.posx,char.posy,char.width,char.length)
end

function love.update(dt)
    if love.keyboard.isDown("right") then
        char.posx = char.posx + 0.4
	elseif love.keyboard.isDown("left") then
        char.posx = char.posx - 0.4 
    end
	

   local width = love.graphics.getWidth()
   local height = love.graphics.getHeight()
   
   if char.posx <= -40 then
   char.posx = (width + 35) - char.width
   elseif char.posx >= (width + char.width) - char.width then
   char.posx = (width - 35) - width
   end
end

No i made it as smooth!

Don't double post, and definitely don't triple post.

[osgeld]

whats it matter in his own thread, its not like there is 15 threads in the forum covering the same topic (which is what I have always considered to be double posting), and you are just derealing the thing anyway ... 2 evils do not make bacon
