Background image. I'm stuck, need help

Post by Lexeres »

I have functions:

Code: Select all

function love.draw()

    for n, myButton in ipairs (buttons) do
        myButton:draw()
    end
    
end

Function code of  myButton:draw() :

    function myButton:draw()
        
        if self.isHover then
        love.graphics.setColor(self.HoverColor)
            if  currentStateMouse == true then
                love.graphics.setColor(self.chooseColor)
            end
            else 
                love.graphics.setColor(self.color)
            end
            
            love.graphics.rectangle("fill", self.x, self.y, self.width, self.height)
            love.graphics.setColor(0,0,0)
            love.graphics.print(self.text,self.x,self.y+2)
            
        end
    
    return myButton
end

function myButton:update(dt)

        mouse = {}
        mouse.x,mouse.y = love.mouse.getPosition()  

        currentStateMouse = love.mouse.isDown(1)

        self.isHover = mouse.x >= self.x and mouse.x <= (self.x + self.width) and
                                    mouse.y >= self.y and mouse.y <= (self.y + self.height)
                                    
        if self.isHover and currentStateMouse == true
                        and self.oldStateButton == false
                then   
                                
                    print("It's a button - ", p.text)
                    love.graphics.setColor(self.chooseColor)

                    if p.text=="Exit" then -- выход из игры по кнопке
                        love.quit()
                    end   

                    if p.text=="New Game" then -- Начало игры
                        print("LOADING...")
                        love.game()
                    end 

                    if p.text=="Options" then -- Настройки
                        print("Settings")
                        
                    end 
        end 
        self.oldStateButton = currentStateMouse   
    end
In love.Load I added backgroundofMenu = love.graphics.newImage("/graphics/123.bmp").
When I add code love.graphics.draw(backgroundofMenu,0,0) in "love.draw()" before cycle - image shows only first frame. If I add love.graphics.draw(backgroundofMenu,0,0) in update-function - Nothing happens.
If I add in myButton:draw() before all the code - all menu buttons are no longer displayed except exit.

How can I add the background image?

this should work:

Code: Select all

function love.draw()
  love.graphics.draw(backgroundofMenu,0,0)
  for n, myButton in ipairs (buttons) do
    myButton:draw()
  end
end
though your code is riddled with globals that i'm assuming you wanted to create as instance variables.
also do use code tags next time

I wrote what "When I add code love.graphics.draw(backgroundofMenu,0,0) in "love.draw()" before cycle - image shows only first frame."

Then you're doing something else wrong; upload your project or show more code... this is just a guess since i can't know, but you might be redefining love.draw elsewhere.

Added attach, my test project.
I think what cycle of buttons somehow overlaps my background picture, but i dont know how to fix it :(

Code: Select all

function love.draw()

    love.graphics.setColor(1, 1, 1, 1) -- you forget somewhere to change colours

    love.graphics.draw(mainMenuPicture) --IT DOESN'T WORK______________________________!!!!!!!!!!!!!!

    love.audio.setVolume(soundVolume)
    love.audio.play(mainManuMp3)

    love.graphics.setFont(sizeFont)

    for n, myButton in ipairs (buttons) do
        myButton:draw()
    end
    
    if love.keyboard.isDown("q") then 
    love.quit()
    end

end
So, i kinda have hard times reading this code, but i guess problem somewhere in buttons draw function
Probably, buttons draw function overwrite colours for "is hover" effect, but don't reset it to default one

look at MainMenu.lua, all the colors set here:
...
color = p.color or {0.5,0.5,0.5,1},
HoverColor = p.HoverColor or {0.8,0.8,0.8,1},
chooseColor = p.chooseColor or {1,1,1,1},
...

I know what the problem is in Draw and cycle, but how to fix - i don't have any ideas((

Thank you very much! It works :D
