1. How do I set the colour of a rectangle to a specific colour, but have text be a different colour.
Code: Select all
function love.draw()
love.graphics.rectangle("fill", 200, 200, 200, 200)
love.graphics.setColor(100,100,100)
love.graphics.print("Test", 500, 500)
end
The above code shows them both as grey. I want just the test to be grey.
2. In the code in question one, I put this line outside the love.draw() function.
Code: Select all
fontsize = love.graphics.newFont(24)
Why wasn't it size 24 font?
3. Must I define the position of a button and check if the cursor is in that area to register if it's clicked? Or is there a better way? If not, what's the best way to manage the method I suggested.
4. What are the most important things to learn in the love API to make a game, so I can learn them first.
5. I was told not to use love.timer.sleep, how else should I stop the program? Should I use love.timer.sleep? Should I have to even stop the program?
Thanks in advance!

1.
Code: Select all
function love.draw()
love.graphics.setColor(0, 0, 0)
love.graphics.rectangle("fill", 200, 200, 200, 200)
love.graphics.setColor(100,100,100)
love.graphics.print("Test", 500, 500)
end
All you had to do was set the color twice.
2. You also have to set the fontsize not just make it. Like so
3. Like menu buttons? Then I would do it like this, using your rectangle in 1.
Code: Select all
function love.mousepresse(x, y, button)
if x > 200 and x < 400 and y > 200 and y < 400 then
-- Whatever you need to do here
end
end
4. I don't believe there is any specific api but I would suggest going through all the tutorials then making a game.
5. To Stop the program as in close it you would use
wherever you need to quit the game.
Hope that answered all your questions.

That really helped, I have two last questions.
Say I create a button using the example in one. How can I define it, so I can edit it?
Code: Select all
button = love.graphics.rectangle("fill",200,200)
button.x = 300
I doubt the above code would work, but it is a example. How would I do something like this?
Lastly, how can I manage special function for each button? Such as for when a certain button has the mouse hovered over it, or if it's clicked. How should I manage specific functions that are specific to certain buttons?

If you wanted to edit it you would probably want to have the button's coordinates in a table like this.
Code: Select all
button = {
x = 200,
y = 200,
width = 200,
height = 200
}
function love.draw()
love.graphics.rectangle("line", button.x, button.y, button.width, button.height)
end
Then if you wanted the button to move when you pressed it you would do something like this.
Code: Select all
function love.mousepressed(x, y, button)
if x > button.x and x < button.x + button.width and y > button.y and y < button.y + button.height then
if button.x == 200 then
button.x = 300
elseif button.x == 300 then
button.x = 200
end
end
end
If you click it it moves.
If you wanted to manage specific things for specific buttons, you would use if and elseif like in above. You just have to keep using elseif for each seperate button. For when a mouse is hovering over it then something like this.
Code: Select all
function love.update()
local x = love.mouse.getX()
local y = love.mouse.getY()
if x > button.x and x < button.x + button.width and y > button.y and y < button.y + button.height then
if button.x == 200 then
button.x = 300
elseif button.x == 300 then
button.x = 200
end
end
end
If you have any other questions feel free to ask.

Those are all really good and well explained. I would also recommend unzipping your favorite love games and looking at the code inside to see if you can learn anything.
