PS VITA / PSTV Project Void v0.1.0 (first alpha)

2017/09/03 : v0.1.0 (first alpha release)

• AIs now use both missiles and standard blaster shots.
• AIs will completely stop if their generator is destroyed, and will use inertia if the engine recalibration is not possible.
• Disable canons and thrusters when the generator is destroyed.
• Make the recalibration button only available when a recalibration is possible.
• Add a volume balance control for each sound data for balancing the sounds.
• Integrate sounds for blaster shot, missile shot, blaster impact, missile explosion, module explosion, and thrusters.
• Add a spatialized sound system to the sound player to handle 3d sounds correctly (pan and doppler effect depending the speed).
• Replace forces by impulses to stop beeing framerate dependant.
• Add canon gauges to the HUD and change the HUD disposition.
• Prevent the engine recalibration to cut all engines when the recalibration is impossible.
• Optimize a bit the asteroid fragment shader.
• Add a batch renderering system for asteroids (this shifted the high CPU consumption to the GPU without any gain of FPS...).
• Fix a weird bug on vita's flare rendering where the flare could sometime blink randomly (no idea what really happened...).
• Add a draw order for sprite rendering, to force the rendering order instead of using the center position depth (used for HUD elements always to be in foreground).
• Add frustrum culling for the particle emitters (per sprite).

- Add some real IA behavior :
- patrol system,
- enemy detection,
- enemy engaging,
- attack vector and target tracking,
- obstacle avoidance given the distance and the mass of the object.
- Improve IA avoidance with the ships and moving objects.
- Fix a bug with the initial values of the debug menu options' preset (default values were not displayed correctly).
- Use batched raycasts for projectile collision detection instead of calculating collisions geometrically (faster as hell).
- Use the exact contact point for the explosion FX source.
- Fix a mystical bug with batched raycasts that were making raycasts return random crap after some asteroids exited the physical world.
- Fix multiple issues with the new projectile raycast batched system.
- Add the new auto lock features and the new HUD system.
- Remove the old free move reticle preset from the debug menu and all options related that are not used anymore.
- Fix some double shockwave explosion fx possibility on high framerates.
- Smooth the avoidance of the AI that was too sharp (now using the same max strafe force as the player).
- Make the auto lock progressive on lock acquired/lost and also resumable.
- Increase the AI detection range and the length of the attack vector.
- Slightly increase the collision radius of the asteroids to better fit with the visual.
- Fix the orientation of axis aligned sprites with non identity local orientation matrix.
- Make the hit FX in the hit target referential.
- Change the hit FX to make lighter and brighter (and smaller).
- Make a cleaner collision handler where the AI can catch proxy/triggers/projectiles collision events.
- Toggle manual/autolock shoot mode with square button.
- Add damages to the projectiles that can destroy any part of the ships.
- Make engine and canon modules destructible as well (for now disabled).
- Make a cheap red color fader proportional to the amount of damage taken.
- Stop the barrel roll for AI while turning.
- Enable the inertia (no inertia dampeners) permanently on the AI if at least one thruster is broken.
- Make destroyed modules physically/visualy destroyed.
- Consider canon and engine below 50% of their HP disabled.
- Add a slow regen for non destroyed modules.
- Add an explosion FX when a module is destroyed.
- Make AIs switch target when the current target is destroyed.
- Make the rotation of the ships proportional to the remaining enabled engines power
(so that a ship with all engines destroyed cannot turn anymore).
- Fix some mistake in the calculation of the torque dampening that could lead to some angular velocity divergence.
- Add an auto target system for the player when no target is selected, if any enemy enters inside the autolock area.
- Make the shoot position displayed and the autolock assist auto target the different modules alive
in a specific order (Engines > Canons > Others).
- Add an additional enemy AI, and an allied AI.
- Fix a wrong friendly fire of the allied AI on the player.
- Use different colors for the target selector and the crosshair depending the target's faction
(white for neutral, red for enemy and blue for allied).
- Change the sphere's color of the ship modules to turn to red with a factor proportionally inverse to the remaining HPs.
- Leave back only 1 AI for framerate purpose.
- Deselect the target if out of display range.
- Remove the pick and drag objects option from the game.
- Hide the HUD when in pause mode.
- [TEMP] Mirror the AI ship relative position from our ship when really far from us.
- Add a stun duration on the AI when one of its module is destroyed, to make it lose control of its ship as a real player would do.

- Double modules' max HP for a longer fight duration.
- Prevent AI stun lock.
- Change the default color of the ships.
- Put the red color of the damaged module on the emissive channel.
- Allow to spawn more AIs (enemy and ally) from the debug menu (need to press reset button to be effective).

- Fix a wrong duplication of the light when resetting the scene.
- Fix the physic damping that was framerate dependant.
- Use real thruster properties for ship's acceleration and strafe.
