Combining text and function

wonderiuy

I need to have an actor display a random image, ie:
I have
image1.png
image2.png
image3.png

so i presume to have a change attribure
self.image = image+random(1,3)+.png
or
self.image = "image"+random(1,3)+".png"

but nothing of above works.
Which is the correct forumula?

Because of the way GS handles its assets (you can rename Attributes and Actors on the fly and all your Behaviors and Rules will reflect the new changes - as a programmer, IMO, this is hot!) but, because of that, you have to create separate Rules to apply changes.

If Attribute is 1, Change Image to 1
If Attribute is 2, Change Image to 2
If Attribute is 3, Change Image to 3

I'm hoping there's going to be a Switch/Case function implemented soon.

Maybe this is old news, but here's one way to accomplish programmatic image reference.

Let's say you have 5 images named display1.png, display2.png, display3.png, etc.
- Create a text attribute ImgName, set this to "display" (no quotes)
- Create a text attribute ImgType, set this to ".png" (no quotes)
- Create an empty text attribute ImgPath
- Create an empty integer attribute ImgNum

To assign a random image to an actor while running your game:
- set the value of ImgNum to your random number: game.ImgNum = random(1,5)
- set the value of ImgPath to game.ImgName..game.ImgNum..game.ImgType (note the double dots)
- set the self.Image of your actor to game.ImgPath

You actor should now be able to randomly display any imported image.
