PlayN & Tripleplay in the ETS Math Assessment Game Challenge

[Paul Gestwicki]

I thought some of you might like to know that my entry to the ETS Math Assessment Game Challenge, Equations Squared, is powered by PlayN and Tripleplay. 

This is the official challenge entry page, which includes a video, summary, links, and some screenshots:

You can also get directly to the game here:

Also, if anyone has any ideas about why tripleplay is acting up on IE9, let me know!

Thanks to all the developers for this fantastic technology stack!

Looks awesome! I have notes lying around for an RPG where battles are
resolved by playing equations against one another using a supply of
numbers, operators and special magic items (code named Digitopolis). I
decided that it was too niche and opted for my current project instead
which is a (very light) RPG where battles are resolved via a
Scrabble-like mechanic (code named Dictionopolis). But I always hoped
to get back to Digitopolis. I like that you combine the grid-building
nature of Scrabble with equations instead of words.

IE9 must implement Canvas.arcTo incorrectly (or differently from other
browsers anyway). TPUI buttons use a round rect background by default
and on HTML5 fillRoundRect is implemented thusly:

private void addRoundRectPath(float x, float y, float width, float
height, float radius) {
float midx = x + width/2, midy = y + height/2, maxx = x + width,
maxy = y + height;
ctx.beginPath();
ctx.moveTo(x, midy);
ctx.arcTo(x, y, midx, y, radius);
ctx.arcTo(maxx, y, maxx, midy, radius);
ctx.arcTo(maxx, maxy, midx, maxy, radius);
ctx.arcTo(x, maxy, x, midy, radius);
ctx.closePath();
}

You can switch to a square rect background when creating your stylesheet:

int bgColor = 0xFFCCCCCC, ulColor = 0xFFEEEEEE, brColor = 0xFFAAAAAA;
Background butBg = Background.bordered(bgColor, ulColor, 5).inset(5, 6, 2, 6);
Background butSelBg = Background.bordered(ulColor, bgColor,
5).inset(6, 5, 1, 7);
Stylesheet sheet = SimpleStyles.newSheetBuilder().
add(Button.class, Style.BACKGROUND.is(butBg)).
add(Button.class, Style.Mode.SELECTED, Style.BACKGROUND.is(butSelBg)).
create();

I'm pleased to share the news that my PlayN/Tripleplay-powered entry to the ETS Math Assessment Game Challenge has won the grand prize. Thanks again to all who contributed to these technologies!

Also, Michael, your arcTo fix is much appreciated, even though I did not upload the patch yet. I wanted to keep the build untouched during judging.
