First of all I totally dig Codea. Been using it for less than a year with amazing results. Huge chunks of my code are take from the examples you guys have shared with the community here, couldn’t have got this far without you guys sharing so Thank you.
I am trying to create a turn based game in the vein of Advance Wars or Tabletop games.
In my game scene I move my “Actors” by tweening them between a list of points but I haven’t been able to implement rotating my actor yet. What I am trying to do (in the rotLeft() function) is Tween from my current position to the same position but at a different angle but it isn’t working.
Do you guys have any suggestions on how i can accomplish this? Here is my Actor class.
-- Actor
Actor = class()
function Actor:init(x, y, size, id, cellx, celly)
self.angle = 0
self.x = x
self.y = y
self.id = id
self.size = size
self.ctrlType = 0
self.scale = 1.0
self.ap = 4
self.clipSize = 4
self.bullVel = 60
self.offset=1
self.startTouch = false
self.showMove = false
self.move = false
self.inactive = 0
self.canMove = 1
self.moving = 2
self.fireing = 3
self.state = self.inactive
self.north = 0
self.east = 1
self.south = 2
self.west = 3
self.dir = self.north
self.moves = {}
self.tab1 = {}
self.buttons = {}
self.bullets = {}
self.grid = {}
self.curBullet = self.clipSize
self.selected = 0
self:reload()
self.index = vec2(cellx or 0, celly or 0)
self.last = vec2(x,y)
tweenObject = vec3(x,y,self.rotation)
end
function Actor:reset()
self.tab1 = {} -- table for points
self.moves ={}
self.offset=1
self.dx=0
self.dy=0
self.showMove = false
self.move = false
self.startTouch = false
self.buttons = {}
end
function Actor:reload()
for i=1,self.clipSize do
local prog = Projectile()
table.insert(self.bullets,prog)
end
end
function Actor:fire()
local bull = self.bullets[self.curBullet]
bull:fire(self.bullVel, self.angle, self.x, self.y, 20)
sound(SOUND_SHOOT, 17108)
self.curBullet = self.curBullet - 1
if self.curBullet < 1 then
self.curBullet = self.clipSize
end
end
function Actor:toggleShowMoves(grid)
if self.showMove then
self.grid = grid
self:makeButtons(self.ap)
else
end
end
function Actor:draw()
dir = self.dir
state = self.state
local a; local b
local line=line
for z=self.offset+1,#self.tab1 do
pushStyle()
stroke(255)
strokeWidth(3)
line(self.tab1[z-1].x,self.tab1[z-1].y,self.tab1[z].x,self.tab1[z].y)
popStyle()
end
for z=self.offset+1,#self.moves-1 do
pushStyle()
stroke(0, 255, 0, 255)
strokeWidth(3)
line(self.moves[z-1].x,self.moves[z-1].y,self.moves[z].x,self.moves[z].y)
popStyle()
end
if self.move then -- try to move at constant speed
a=math.sqrt(self.dx*self.dx+self.dy*self.dy)
b=5/a
end
pushMatrix()
rotate(self.angle)
scale(self.scale)
batch:sprite("cmane",self.x,self.y)
if self.selected > 0 then
pushStyle()
tint(64, 255, 0, 255)
batch:sprite("mselect",self.x,self.y)
popStyle()
end
if self.show then
pushStyle()
tint(253, 0, 255, 255)
batch:sprite("jammed",self.x-20,self.y+20)
popStyle()
end
if self.startTouch then
pushStyle()
tint(255, 0, 0, 255)
batch:sprite("jammed",self.x-20,self.y+20)
popStyle()
end
if self.showMove then
pushStyle()
tint(64, 255, 0, 255)
batch:sprite("overwatch",self.x+20,self.y+20)
popStyle()
end
popMatrix()
self:takeMove()
self:drawList(self.bullets)
if self.ctrlType == 0 then
if self.showMove then
if self.selected > 0 then
self:drawList(self.buttons)
else
self.showMove = false
end
end
end
end
function Actor:rotLeft()
self:tweenSelfStep(0,self, {rotate = 270})
end
