Question about Mari0 programming

[MissingNo98]

Hi. I now have lua(löve) in school and i wanted to make a sidescoller game. But i don't know how to make it actually sidescolling. Perhaps i could put a camera to an objekt or sth. like this but i don't know how to do this. Would be cool if someone answers.

PS.: I hope Mari0 SE will come out soon : )

You simply offset all drawing operations by the amount of pixels that you want the screen to be scrolled.
If you're lazy, you could use love.graphics.translate.

thx

[MissingNo98]

thx. And how did u make the collision?

[MissingNo98]

Pehaps with just coordinates but i'm not sure if it can be made easier.

And another question: How is the best method of making a circle following my mouse? I tried it but it isn't very pretty.

function love.load()
kreisX = love.mouse.getX()
kreisY = love.mouse.getY()
end

function love.draw()
love.graphics.setColor(255,255,0)
love.graphics.circle("fill",kreisX,kreisY,15,15)
end

function love.update(dt)
if kreisX < love.mouse.getX() then
kreisX = kreisX + speed
else
if kreisX > love.mouse.getX() then
kreisX = kreisX - speed
end
end
if kreisY < love.mouse.getY() then
kreisY = kreisY + speed
else
if kreisY > love.mouse.getY() then
kreisY = kreisY - speed
end
end
end

Code: Select all

function love.load()
    kreisX = love.mouse.getX()
    kreisY = love.mouse.getY()
end

function love.draw()
    love.graphics.setColor(255,255,0)
    love.graphics.circle("fill",kreisX,kreisY,15,15)
end

function love.update(dt)
    kreisX = love.mouse.getX()
    kreisY = love.mouse.getY()
end

Or even just

Code: Select all

function love.draw()
    love.graphics.setColor(255,255,0)
    love.graphics.circle("fill",love.mouse.getX(),love.mouse.getY(),15,15)
end

Thx but the circle should come after the mouse not BE the mouse.

[Maurice]

Then look into smoothing.

Thx but the circle should come after the mouse not BE the mouse.

you can use simple trigonometry to make it move towards the mouse. but you don't really want to do that as a beginner

No, this is the perfect thing to do as a beginner.
