Change Image with Change Attribute?

perfectanswer

Hello,

to save a big amount of rules, my idea is to change my images not with the ChangeImage behavior, but instead of this I will use the Change Attribute behavior like this:

Change Attribute:>self.image = MyImageName_1.png
But...
How I can change the number?
The number ad the end of the image name is a attribute (GUINumber(int))
So the Name looks like MyImageName_GuiNumber.png I see the before a while ago here in the forum or on youtube, but I can't find anymore. Anyone know the syntax for this?? Thanks in advance Bernd

Hi Bernd

The syntax for this would be:

self.image = MyImageName_..GUINumber(int)..".png"

The double dot is really useful for concatanating attributes with text, etc.

Maybe just in case of a problem, don't use the underscore (_), so it'd be a bit cleaner:

self.image = MyImageName..GUINumber(int)..".png"

Hi Gyroscope,

many thanks for helping me out.
Works great, the underscore don't stop the show. If I ran in trouble with this I can rename the files and change the filenames in the xml, but.. just for the case.
Anyway, THIS is a great way to shrink the rules to a minimum.
Thanks again Giro!

I just saw this post and I think it would help me with my game, but I don't get it.
I have 20 images, named 00.PNG to 20.PNG.
If I want to change the actor's image to the next number, what should I do with my rule?
What I don't understand is when you said: "The number ad the end of the image name is a attribute (GUINumber(int))"
What is a GUINumber?
When I try to go to the next image I'm getting only a white square. If I could understand the the GUINumber thing I think I can get it. Currenty I am doing it with change image behiavior. Thanks!

I am bumping this, just looking for more information on how to change the self image attribute. I know it's explained in this post but I can't manage to make it work. Any help is welcomed.
Thanks.

easiest way: name images 0 through 8 or whatever (No text…only numbers)

then changeAttribute: self.image TO: self.Image+1

for several imageAnimations: make names of the image of the sequence in double digits: … 10 through 19; 20-29; etc.

Thanks so much MotherHoose, from now I will start any image sequence with the number 10.
It's working and I saved 19 rules.

MotherHoose

glad @GhostShipApps you got the progression!

why are you saving those 19 rules? toss them out! 8-|

forgot to tell you to have the image changes enclosed in a
Rule: when (All)
Attribute: self.Image ≥ 0
Attribute: self.Image ≤ 9
--then do the changeAttributes

don't want the computer to keep on adding and then display a 20.png image.

Previously, for every new image I needed I had a change image rule into the actor. I couldn't use animation because the image displayed depends on the position of the actor. Now I just change the self image.
thanks again

would be great if there was a template for this! I'm having issues with it.

Heh figured this out and used timers with it control the animation. I think I just misinterpreted some of the things u said. Thanks!
