Hello, I'm learning developement with Love2D and i've a problem with animation. (I'm french then i'm sorry for my English)
i want lunch an animation when i pressed a button of my mouse ("1") but i need stay pressed to view completely my animation. I expect is simple problem but i've already try 2 ou 3 tutorial to understand but... I don't.

I'm trying do a simple TDS, i've programme all function i want but i'm trying implent animation to have a better game !

I send you my code !

Thank's to you ! (I'm here if u need more information !)

Code: Select all

--! file: player.lua

Player = Object:extend()

function Player:new()
    self.x = 300
    self.y = 100
    self.speed = 500
    self.width = 149
    self.height = 182

    self.state = "idle"
    self.move = false
    self.shot = false

    self:loadAssets()
end

function Player:loadAssets()
    self.animation = {timer = 0, rate = 0.1}
 
    self.animation.run = {total = 6, current = 1, img = {}}
    for i=1, self.animation.run.total do
       self.animation.run.img[i] = love.graphics.newImage("assets/Walk_gun/Walk_gun_00"..i..".png")
    end

    self.animation.idle = {total = 1, current = 1, img = {}}
    for i=1, self.animation.idle.total do
       self.animation.idle.img[i] = love.graphics.newImage("assets/Walk_gun/Walk_gun_00"..i..".png")
    end

    self.animation.shot = {total = 5, current = 1, img = {}}
    for i=1, self.animation.shot.total do
       self.animation.shot.img[i] = love.graphics.newImage("assets/Gun_shot/Gun_shot00"..i..".png")
    end
 
    self.animation.draw = self.animation.run.img[1]
    self.animation.width = self.animation.draw:getWidth()
    self.animation.height = self.animation.draw:getHeight()
 end

    dx, dy = mouse_x - self.x, mouse_y - self.y
    -- calcul de l'angle
    angle = math.atan2(dy, dx) - 1.57
    
    
end

    elseif self.shot then
       self.state = "shot"
    else

    end
 end

function Player:animate(dt)

    self.animation.timer = self.animation.timer + dt
    if self.animation.timer > self.animation.rate then
       self.animation.timer = 0
       self:setNewFrame()
    end
end

function Player:setNewFrame()
    local anim = self.animation[self.state]
    if anim.current < anim.total then
       anim.current = anim.current + 1
    else
       anim.current = 1
    end
    self.animation.draw = anim.img[anim.current]
end

function Player:draw()

    love.graphics.draw(self.animation.draw, self.x, self.y, angle, 0.5, 0.5, self.animation.width / 2, self.animation.height / 2)
    love.graphics.print(self.width, 10, 10)
    love.graphics.print(self.height, 10, 30)
    love.graphics.print(angle, 10, 50)

end

The problem might be the quotes around "1". Use love.mouse.isDown(1) instead of love.mouse.isDown("1").

Also, if you want people with other keyboards to be able to use your game, use love.keyboard.isScancodeDown instead of love.keyboard.isDown, specifying WASD instead of ZQSD. That way it will work the same no matter the language of the keyboard.
