Hey pls help me i want make button because i make platformer
İ want make if buttontouch=true then charx +=5
One way to do it is to type this into ChatGPT:
Give me a super simple Codea program that draws a button that says button and above it a circle and every time you tap the button the circle moves 5 pixels right.
And it will give you something like this:
function setup()
x = WIDTH / 2
end
function draw()
background(40)
fill(255)
ellipse(x, HEIGHT / 2 + 100, 50)
fill(100, 150, 255)
rect(WIDTH / 2 - 75, 100, 150, 60)
fill(255)
fontSize(24)
text("button", WIDTH / 2, 130)
end
function touched(touch)
if touch.state == ENDED then
if touch.x > WIDTH / 2 - 75 and touch.x < WIDTH / 2 + 75
and touch.y > 100 and touch.y < 160 then
x = x + 5
end
end
end
Also here is a VERY simple platformer kit to get you started. You tap wherever you want to make a platform and it fills in green.
--# Main
function setup()
viewer.mode = FULLSCREEN
world = World()
player = Player()
end
function draw()
background(40)
pushMatrix()
translate(WIDTH / 2 - player.pos.x, HEIGHT / 2 - player.pos.y)
world:draw()
player:draw()
popMatrix()
player:drawControls()
end
function touched(touch)
player:touched(touch)
world:touched(touch)
end
--# World
World = class()
function World:init()
self.size = 40
self.cells = {}
self.floorY = math.floor(HEIGHT / 3 / self.size)
for x = -10, 20 do
self:setCell(x, self.floorY, true)
end
end
function World:key(x, y)
return x .. "," .. y
end
function World:setCell(x, y, value)
self.cells[self:key(x, y)] = value
end
function World:getCell(x, y)
return self.cells[self:key(x, y)] == true
end
function World:draw()
local left = math.floor(
