[4.5.9] Easy Creating a unique boss death animation (ModMetroidvania)

[TalkingCat]

In my game, I want to create an animation of the death of a boss different from the death of an ordinary monster. I hope it will be useful to someone, because I spent a lot of time on it. I apologize in advance for the grammar, English is not my native language. So let's get started.

1. After destroying the monster object, we add a screen type check to the hurtMonster_Platform Base.asm script. In my case, the screen type is 1.
2. Create a game object and call it BossDeath. In my case, he is number 8.

 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
            LDA screenType
            CMP #1                ;Checking the screen type
            BNE notAbossRoom
            
                ;;;;;;;;;;;;;;;;;;;;;;;;Creating an object in place of a destroyed monster
                LDA Object_y_hi,x
                STA tempB
                LDA Object_x_hi,x
                STA tempA
                LDA Object_screen,x
                STA tempC
                TXA
                PHA
                CreateObjectOnScreen tempA, tempB, #$08, #$00, tempC  ;;<-- the game object #08  or any other object item you want to drop
                PlaySound #sfx_boom2
                PLA
                TAX
                ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
            
        notAbossRoom:
        ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

3. In the object settings, we set the action as GoToWarp if we want the player to move to the victory screen after the animation ends.


I'm just starting to learn Newsmaker and Assembler. Suggestions for improving the code are only welcome)
My code hurtMonster_Platform Base.asm:

    TXA
    STA temp
    GetActionStep temp
    CMP #$07 ;; we will use action step 7 for hurt.
    BNE +doNotSkipHurtingThisObject ;; if he is hurt, he can't be hurt again.
        JMP +doSkipHurtingThisObject
+doNotSkipHurtingThisObject:
        ChangeActionStep temp, #$07
        LDA #$01 
        STA Object_action_timer,x
        DEC Object_health,x
        PlaySound #sfx_vector
        LDA Object_health,x
        BEQ +doNotSkipHurtingThisObject
            JMP +doSkipHurtingThisObject
+doNotSkipHurtingThisObject:
        
            LDA Object_x_hi,x
            CLC
            ADC #$05
            STA tempA
            LDA Object_screen,x
            ADC #$00
            STA tempD
            LDA Object_y_hi,x
             CLC
            ADC #$04
            STA tempB
            LDA Object_direction,x
            AND #%00000111
            STA tempC
            
            DestroyObject
            
            CreateObjectOnScreen tempA, tempB, #$0C, #$00, tempD
            
            PlaySound #sfx_boom
                                
      
        ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
            LDA screenType
            CMP #1                ;Checking the screen type
            BNE notAbossRoom
            
                ;;;;;;;;;;;;;;;;;;;;;;;;Creating an object in place of a destroyed monster
                LDA Object_y_hi,x
                STA tempB
                LDA Object_x_hi,x
                STA tempA
                LDA Object_screen,x
                STA tempC
                TXA
                PHA
                CreateObjectOnScreen tempA, tempB, #$08, #$00, tempC  ;;<-- the game object #08  or any other object item you want to drop
                PlaySound #sfx_boom2

        notAbossRoom:

            +notZeroCount
    +doSkipHurtingThisObject

Gave this a go. Using 4.5.9 metroidvania. Screen type one works great for Bosses! ,but nothing happens with regular monsters. I set the monster action step up and and object I wanted but no go.
