Background image. I'm stuck, need help

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((

Code: Select all
function myButton:draw()
local r, g, b, a = love.graphics.getColor() -- before you draw buttons, you should get old colors (and alpha)
volumeInPercent = soundVolume * 100
if p.text=="Sound" and volumeInPercent > 0 then
self.text = "Sound: " .. soundVolume
if soundVolume > 1.05 then
print("Sound: OFF")
else
self.text = "Sound: " .. volumeInPercent
print("Sound:" .. volumeInPercent)
end
end
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(r, g, b, a) -- and after you done, return old colours
love.graphics.print(self.text,self.x,self.y+2)
end

Thank you very much! It works
