when the buff2.0 is used , the jetfighter's blood should not be deducted
[Description] I have encountered a bug in my shooter game where the jetfighter's health score is incorrectly deducted when using Buff 2.0. According to the game's design, when the Buff 2.0 is used, it should only affect the enemy's health score and not reduce the jetfighter's health. However, when I activate the Buff 2.0, the jetfighter's health score is also reduced, resulting in an unintended decrease in the jetfighter's health. [Steps to Reproduce] 1. Launch the shooter game. 2. Acquire and activate the Buff 2.0 power-up. 3. Observe the jetfighter's health score when colliding with enemies or obstacles. [Actual Result] When using the Buff 2.0, both the enemy's health score and the jetfighter's health score are reduced upon collision with enemies or obstacles. This behavior is inconsistent with the intended functionality of the Buff 2.0, which should only affect the enemy's health score. [Expected Result] The expected behavior when using the Buff 2.0 is as follows: 1. The Buff 2.0 power-up should only affect the enemy's health score when colliding with them. 2. The jetfighter's health score should remain unaffected and not be deducted when using the Buff 2.0. 3. The Buff 2.0 should provide an advantage by allowing the player to eliminate enemies and reduce their health score without compromising the jetfighter's health.
