v1.0.3 Update - Performance Optimization

Intro

Update Notes

Overview

• In the last version, a performance optimization mechanism was updated: When the number of projectiles on screen reaches a certain amount, newly generated projectiles of all types will be merged.
  
• However, its effectiveness was limited. The optimization was unstable, and it affected visual performance and game feel even when the game was not lagging.
  
• Therefore, in this update, it has been reworked into a series of new optimization mechanisms. This aims to significantly reduce performance costs in the late game without affecting normal gameplay.
  
• For convenience, these new optimization mechanisms will be referred to as "New Mechanisms" below.
  
• Relaxed the on-screen projectile threshold for triggering the New Mechanisms from 300 to 900. Also, real-time frame rates are now considered; low frame rates will automatically trigger the mechanisms.
  

Blast Wave Optimization

• Refactored the range detection logic for blast waves, significantly reducing their performance costs in various situations.
  
• Now, when triggering the New Mechanisms, or when blast effect is hidden in settings, Blast logic calculations will be simplified (instead of updating calculations every frame as the animation expands, all calculations are completed in the first frame based on the maximum animation range).
  

Invincibility Optimization

• Invincibility frames are one of the major causes of late-game lag.
  
• By default, players gain brief invincibility after colliding with enemies to allow for reaction time. During this time, colliding with enemies deals no damage to players and does not destroy enemies, but knocks them back. However, at low frame rates, invincibility causes serious performance issues. Massive enemy stacking and knockbacks create extremely high physics calculation loads. If the Challenge Gravity is also enabled, repeatedly pushing and pulling enemies generates terrible performance costs.
  
• So adjustments have been made.
  
• Now, when triggering the New Mechanisms, colliding with enemies no longer triggers invincibility.
  
• Reworked Challenge Gravity: Added effect, upon colliding with enemy, no longer gain invincibility. The gravity effect now has an internal cooldown of 0.1 seconds. Score Multiplier increased from x115% to x125%.
  

Mines Optimization

• At the stage where the New Mechanisms are triggered, there are usually thousands of mines on the field, and thousands of grenades are fired via the upgrade Chain Blast, so adjustments have been made to mines.
  
• Now, when triggering the New Mechanisms, spawning mines will also be merged.
  
• A series of detailed adjustments ensure balance and gameplay are unaffected:
  
• If the upgrade Mine Fusion is owned, a fused large mine is spawned directly, skipping intermediate evolution calculations;
  
• otherwise, a normal mine with multiplied damage is spawned. Triggering the upgrade Recycled Mines with it will restore multiplied energy, and the upgrade Chain Blast will fire a single grenade with multiplied damage.
