Re: Manual Questions

You can do either (or even both at the same time). It depends on what  
exactly you want to do, there are a lot of combinations.

If you want to display the "congratulations" box on a screen of its  
own, you can make it a separate slide. If you want to display it on  
top of a panorama, make it a slide with transparency (scaled to fit  
the screen) or a panel (kept at screen resolution) and display it as  
an overlay. If you want to display it on top of one particular slide,  
you can make it a patch on that slide node.

If you are satisfied with Pipmak's text rendering and don't need any  
fancy effects on the text, or want to be able to change the text  
easily, you can use image:drawtext. Otherwise, you draw the text  
yourself in a graphics program and incorporate the result as an image.

Here's a working example of a slide with a background picture and a  
patch containing drawn text (using a built-in image and font for  
demonstration, you will want to use your own image and perhaps your  
own font):

--------
slide "../resources/missing.png"

patch {
   x = 0, y = 50,
   image = pipmak.newimage(128, 20):color(1, .5, 0):drawtext(64, 0,  
"congratulations", "../resources/Vera.ttf", 16, pipmak.center)
}
--------

You could also draw the text directly on the background image:

--------
local img = pipmak.newimage("../resources/missing.png")

img:color(1, .5, 0):drawtext(64, 50, "congratulations", "../resources/
Vera.ttf", 16, pipmak.center)

slide (img)
--------

Or even create the whole background image programmatically:

--------
slide (pipmak.newimage(640, 480):color(1, .8, .5):fill(150, 200, 340,  
80):color(.4, .2, 0):drawtext(320, 210, "congratulations", "../
resources/VeraBd.ttf", 24, pipmak.center))
--------

Does that help? I admit that this is all a bit complicated and low-
level, that's why Andrea has created a more user-friendly text display  
system on top of it that will be integrated into the next version of  
Pipmak: http://thread.gmane.org/gmane.games.devel.pipmak.user/454

No. You need to keep track of that yourself if you need it, by adding  
an onenternode handler to every node that takes the node number and  
appends it to some list in the state table, or something. You could  
put that into its own file and include it in all the nodes using  
pipmak.dofile() to avoid duplication.


What you want is "pipmak.print", not "print.pipmak". The function  
that's stored under the name "print" in the table "pipmak". What  
you're trying here is to get the entry named "pipmak" in the global  
variable "print", which doesn't work because "print" is not a table  
but a function (one that prints to standard output, which is of  
limited use in Pipmak).
