OP4JS Alpha aka SmartMobileStudio is in the wild
We’ve now sent “Smart Mobile Studio” Alpha version to 50 testers.
Did you miss the beta invite?
Visit www.SmartMobileStudio.com [2] to participate.
SmartMobileStudio leverages DWScript’s JavaScript CodeGen.
My first test app with the alpha was a clock, check it in your iOS or Android Browser [3] or in the Android market [4]. Source is included in the alpha. Will be beautified it later on 🙂
I’ve been playing on another one, head over to YouTube to see a small video [5], you can also get the apk [6] (47 kB), but beware it’s basic, ugly, and definitely early alpha, but it’s coded in Pascal!
Below is a snippet of the source code (using DWS inline implementations for illustration and compactness purposes, most of OP4JS is written in the more classic interface/implementation style), it’s a snip of the root class of the mini-engine of the game (yes, virtual methods are supported):
type
TEntity = class
X, Y : Float;
function Progress : Boolean; virtual;
begin
// does nothing by default
end;
constructor Create(aX, aY : Float);
begin
X := aX;
Y := aY;
end;
function Dist2(entity : TEntity) : Float;
begin
Result := Sqr(X-entity.X)+Sqr(Y-entity.Y);
end;
end;
Other recent changes to the DWScript SVN
- Added sample/simple IndyWebServer demo, implements basic “pascal server pages” and demonstrates how to use DWS in a multi-threaded environment. Makes use of RTTI Environment class to expose WebRequest & WebResponse. Expect more details in a future post.
- TTerminatorThread has been replaced by TGuardianThread, which can “guard” multiple executions
- Dotted unit names are now supported
- Random no longer uses the Delphi RTL but XorShift [7]
- unit name symbols are now included in the Symbol Dictionary
- include references are now included in the Symbol Dictionary
- TdwsSuggestions can now optionally suggest reserved words (begin, procedure, etc.)
- fixes for Inc() & Dec() when operating on references with side-effects.
- improved several error messages related to parameter passing.
- other misc. fixes and optimizations, more unit tests.
