Hi there pros!
I am in the first stage of my game and have started out with the control of movement and change of sprite sequences - depending on the direction the character is moving.
A touch on the screen makes the character fly, and a drag makes him move to that direction. And if you drag to the opposite, he turns and flies at the other direction. This involves three animations.
So, we start with the first codeblock where I check to see in what direction the player wants the character to fly.
local function getSpriteSeq(event)
SPRITE\_STATE = event.sprite.sequence
end
Runtime:addEventListener("touch", moveforward)
local function moveforward( event)
--\> Save startposition when dragging
if(event.phase=="began") then
x0 = event.x
end
--\> Check what direction we are going for...
if(event.phase=="moved") then
if not (player==nil) then
if(x0 \< event.x) then
--\> Flying forward
player:applyLinearImpulse(.02, 0, player.x, player.y)
if(SPRITE\_STATE=="fly\_left") then
display.getCurrentStage():setFocus(nil)
player:prepare("turn\_right")
player:play()
end
else
--\> Flying backward
player:applyLinearImpulse(-.02, 0, player.x, player.y)
if(SPRITE\_STATE=="fly\_right") then
display.getCurrentStage():setFocus(nil)
player:prepare("turn\_left")
player:play()
end
end
end
end
display.getCurrentStage():setFocus( nil )
end
So first thing i do is to check what sprite sequence we are dealing with. I added “getSpriteSeq” as a listener to the player sprite.In that function I collect the current animation name. I then added a listener for touch input to check in what direction the user want the animations to go. If going backward, I start to play the “Turn back” sequence. And vice-versa if the player wants to go forward. These animations are short and turns the animation around.
Then I have this listener that checks if the “turn” animation is done. If so - the play the regular fly animation.
local function spriteListener( event )
if(SPRITE\_STATE=="turn\_left") then
if(event.sprite.currentFrame==20) then
--\> The turn left animation is done, now play the fly left.
player:prepare("fly\_left")
player:play()
end
end
if(SPRITE\_STATE=="turn\_right") then
if(event.sprite.currentFrame==20) then
--\>The turn right animation is done, now play fly right.
player:prepare("fly\_right")
player:play()
end
end
end So my question is basically, is this the correct way to handle the animations sequences - or is there a better way? Is this bad programing or could it work for a sharp release?
