Changelog / Revision History

V1.5.20180201

Big feature updates!

• Game "mostly" now works on mobile devices. Touch-based events for helicopter control, UI for helicopter weapons and inventory / ordering. Tested on iPhone X. Others should work reasonably-well. Hopefully.

• Inventory order queueing! 🎉 (Finally.) e.g., 3 tanks in a row. Queueing deducts funds immediately. No added UI or cancel ability (yet.)

• Battlefield view is now bigger on screen. Stats UI is dead, long live stats.

• Performance improvements. tl;dr: JavaScript tweaks, putting most all sprites onto the GPU. Replaced most common animated .GIF backgrounds with 3d-transform, GPU-accelerated CSS animation-driven sprites. 😅

Sound

• No sound for any Safari (desktop or mobile) for now, including version 11.0. Multiple sounds kill performance on desktop, and "auto-play" is effectively blocked on mobile. https://bugs.webkit.org/show_bug.cgi?id=116145

• New + improved helicopter machine gun sounds. 9 different samples, played at random.

• New sound effects: "bomb hatch" (helicopter bomb release), tank gunfire, bunker chain/balloon repair, helicopter gunfire hit.

• "Medals clanking" sound for bunker chain/balloon repair. (BY-NC 3.0.) https://freesound.org/people/Gareth_H/sounds/365799/

• New tank gunfire sound: "Tank Fire Mixed.wav" by Cyberkineticfilms/freesound.org (CC0, "No Rights Reserved". 🙇)

• Hat tip: "Bolo" "tank self hit" sound effect, Copyright (C) Steuart Cheshire 1993. My favourite Mac game of all time. ❤️

UX / UI

• "Radar jammed" TV static-like overlay with transform sprite.

• Slightly faster helicopter bombing rate - more responsive.

• Chain refactor. Use fixed height, animate via transform, fall with gravity when balloon and/or bunker are lost.

• Balloons are yellow-ish on radar, and now transform-rotated to elliptical shapes. Bunkers / base color and border tweaks, friendly vs. enemy now look different.

• Inventory and helicopter ammo, etc., become greyed out when unaffordable / unavailable.

• Target / "tracking" animation on Smart Missile targets.

• Smart Missiles can now re-target on the next frame after the original target dies. If a new target can not be immediately acquired, the Smart Missile dies as previously.

• Radar items, clouds and some other sprites move more smoothly simply by dropping parseInt().

• "C" / rubber chicken use causes UI to switch to rubber chicken mode.

• Possible bugfix: If paused and enemy order timer fires, re-start timer. This probably fixes enemy inventory building sometimes breaking.

• Jam radar all the time on hard + extreme game types.

Miscellany

• Note re: Firefox will-change memory consumption warning that might show in console.

• URL feature flags: noTranslate3d and noRadarGPU. frameRate=[60|*] for testing of requestAnimationFrame() timing. camelCase others. Let Opera (now webkit-based) have transforms.

• +makeTransformSprite(), a sort of sub-sprite for CSS transform-based animations (GPU-accelerated animated .GIF alternatives.)

z-index: -1 can be harmful for performance / compositing.

• iPhone X notch handling based on orientation and whatnot.
