Another build<\/a>, this one came almost an hour and a half after the last one. This one now shows the controls so I don’t have to go and write that here every time \ud83d\ude1b It also has limited ammo – you get one shot from the pickup.<\/p>\n

Something cool I used for this is a bit of code I had lying there, not sure that it would come to use: Layout.<\/p>\n

This is Layout:<\/p>\n

<\/span>package fireball.gfx.util;<\/p>\n

import flash.display.DisplayObject;<\/p>\n

class Layout
\n {<\/p>\n

public static inline function sTopbTop(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(px);
\n }<\/p>\n

public static inline function sTopbCenter(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(px-ti.height*0.5);
\n }<\/p>\n

public static inline function sTopbBottom(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(px-ti.height);
\n }<\/p>\n

public static inline function sCenterbTop(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(Game.YRES*0.5+px);
\n }<\/p>\n

public static inline function sCenterbCenterY(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(Game.YRES*0.5+px-ti.height*0.5);
\n }<\/p>\n

\n {

\n }<\/p>\n

public static inline function sBottombTop(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(Game.YRES-px);
\n }<\/p>\n

public static inline function sBottombCenter(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(Game.YRES-px-ti.height*0.5);
\n }<\/p>\n

public static inline function sBottombBottom(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(Game.YRES-px-ti.height);
\n }<\/p>\n

public static inline function sLeftbLeft(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(px);
\n }<\/p>\n

public static inline function sLeftbCenter(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(px-ti.width*0.5);
\n }<\/p>\n

public static inline function sLeftbRight(ti : DisplayObject, px : Float) : Int

\n {
\n return Std.int(Game.XRES*0.5+px-ti.width*0.5);
\n }<\/p>\n

public static inline function sCenterbRight(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(Game.XRES*0.5+px-ti.width);
\n }<\/p>\n

public static inline function sRightbLeft(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(Game.XRES-px);
\n }<\/p>\n

public static inline function sRightbCenter(ti : DisplayObject, px : Float) : Int
\n {
\n return Std.int(Game.XRES-px-ti.width*0.5);

\n }<\/p>\n

Very simple, but highly useful. On all the functions that take an x and y coordinate, I can pass in Layout functions to transform them.<\/p>\n

However, I have a flaw in how I’m doing font rendering that is going to limit the utility of Layout for this game. The flaw is – Flash does not autosize TextFields at the moment of instantiation, as far as I can tell. Not only that, but I don’t use TextFields directly; I render them to bitmaps, because I want to cache that data. Hence to get around these flaws I’m oversizing the surfaces I draw the text to with a bad heuristic(32px height and width per character).<\/p>\n

I think that in the future I may switch to a solution based on the Polygonal library’s font rendering solution<\/a>. Although it’s a little bit cumbersome(compilation process vs. drop in a ttf), a little bit less Flash-friendly, this will give me good data to work from, and the basic render speed is faster too.<\/p>","time":"April 24th, 2010 8:35 am","title":"Pincer \u2013 HUD and ammo"}
