[Feature] HP Bars for NPC

[Labmonkey]

[SERVERSIDE]
First we have to add a new packet
In mod Enumerations under

Code:

SCastSpell

put

Code:

SUpdateNpcHP

Now let us make the sub to send the packet

AT the bottom of modServerTcp put

Code:

Public Sub SendNpcHp(ByVal Map As Long, ByVal Index As Byte)
    'check if the npc is dead
    If MapNpc(Map, Index).Vital(Vitals.HP) = 0 Then
    Call SendDataToMap(Map, SUpdateNpcHP & SEP_CHAR & Index & SEP_CHAR & 0 & SEP_CHAR & 0 & END_CHAR)
    Else
    Call SendDataToMap(Map, SUpdateNpcHP & SEP_CHAR & Index & SEP_CHAR & MapNpc(Map, Index).Vital(Vitals.HP) & SEP_CHAR & Npc(MapNpc(Map, Index).Num).Stat(Stats.Strength) * Npc(MapNpc(Map, Index).Num).Stat(Stats.Defense) & END_CHAR)
    End If
End Sub

Now lets send the packet. In the attacknpc sub, under

Code:

' Reduce durability of weapon
    Call DamageEquipment(Attacker, Weapon)

put

Code:

'Lets update the hp of the npc incase it got hurt
    Call SendNpcHp(GetPlayerMap(Attacker), MapNpcNum)

[CLIENTSIDE]
We have to add the new packet to the client too.
In mod Enumerations under

Code:

SCastSpell

put

Code:

SUpdateNpcHP

We have to add a value to MapNpcRec called MaxHp
Find

Code:

Private Type MapNpcRec

under

Code:

AttackTimer As Long

put

Code:

MaxHp As Long

Now lets actually change the hp when we get the packet.
in modHandleData under

Code:

HandleSpellCast Parse

put

Code:

Case SUpdateNpcHP
            HandleUpdateNpcHP Parse

now at the bottom of modHandleData put this sub

Code:

' ::::::::::::::::::::::::::
' :: Update Npc Hp packet ::
' ::::::::::::::::::::::::::
Private Sub HandleUpdateNpcHP(ByRef Parse() As String)
    MapNpc(CByte(Parse(1))).Vital(Vitals.HP) = CLng(Parse(2))
End Sub

Now the last step, draw the hp bar. In sub BltNpc at the bottom put

Code:

If MapNpc(MapNpcNum).Vital(Vitals.HP) = 0 Then Exit Sub
        
        Call DDS_BackBuffer.SetFillColor(RGB(255, 0, 0))
        Call DDS_BackBuffer.DrawBox(X, Y + 32, X + 32, Y + 36)
        
        Call DDS_BackBuffer.SetFillColor(RGB(0, 255, 0))
        Call DDS_BackBuffer.DrawBox(X, Y + 32, X + ((MapNpc(MapNpcNum).Vital(Vitals.HP) / 100) / (MapNpc(MapNpcNum).MaxHp / 100) * 32), Y + 36)

I having a little trouble getting this over to MS4, solely because ive been programming for over 12 hours on it lol, can anyone give me a hand by letting me know how i can get an NPC max health, on the client side? or do I have to make another packet? any help would be absolutely fantastic.

What do you mean it sends the packet at the wrong time?

And the tutorial was written for an earlier version of ms, and i can guarantee for that version it worked fine.

All is needed is MP and SP bars.
