How to use a Movie Clip

Fish · March 2014

I have the following code...

local mc = MovieClip.new{
{1,10,highScoreTex,
{
x = {0, config.left + config.halfWidth - highScoreTex:getWidth()/2, "linear"}
}
}
}

This moves the text from the left to the center of the screen but it does it really fast.
So to slow it down i changed it to this...

local mc = MovieClip.new{
{1,50,highScoreTex,
{
x = {0, config.left + config.halfWidth - highScoreTex:getWidth()/2, "linear"}
}
}
}

But the text never makes it to the center of the screen and stops early. How would i slow down the animation but have it reach the same destination?

@Fish do you do anything else with MovieClip? like setting stop frames, etc?

Fish · March 2014

That's all the code i have for the movie clip, nothing else. Do i need stop frames?

hmm, thats just interesting, will do some tests,
but how far it is till center and from which frame (adding up from 10 to 50) does it start to happen?

Fish · March 2014

if i set it to 10 it goes all the way to the center, 50 it goes 3/4 way to the center, 100 1/2 way to the center. I don't understand what you mean by which frame does it start to happen.

@Fish,
where are your config settings coming from? config.halfWidth, etc

secondly, is your project settings and your simulator running at the same resolution? Are you sure that your settings are not for 320x480 and running at 640x960 or vice-versa.

Lastly,
I am not sure why for setting the Y axis (Vertical) you are using left, and width, you should be using top and height.

the config.halfWidth and stuff are defined in another lua file, they just define generic points on the device like config.left is the pixel all the way to the left, config.halfWidth is the middle pixel on the x axis.

I just tried running both at the same resolution (480,800) but the results are the same.

I'm not changing the Y axis, I'm changing the x position of the object.

@Fish,
ahhh, sorry at first glance it reads like {0, left + width} so it seemed like you are manipulating the Y axis and the X is 0.

what was I thinking, you are using a movie clip...

_W = application:getDeviceWidth()
_L = 10
 
local highScore = TextField.new(nil,"High Score")
highScore:setPosition(10,50)
stage:addChild(highScore)
 
local mc = MovieClip.new
	{
		{1, 50, highScore,
			{
				x = {0, _L + (_W - highScore:getWidth())/2, "linear"}
			}
		}
	}

Here, try to adjust this to your liking, this centers the text.

Huh it works now... I dont know what changed but thanks guys

. Maybe i just suck at lua, I think i just need to get used to scripting :P

Sorry scratch that. It sometimes works and it some times doesn't. After retesting a bunch it just stopped working. I'm really confused now.

@Fish and if you change application:getDeviceWidth() to application:getContentWidth() does it help?

Because it all depends on the project settings you have
