Hi People! so iv been searching through everything to find how to give my melee attack 1 point of damge to an enemy and my projectile do 3! aaaand iv just made a solution!
this is in my metrovania game but im sure the process could be adapted and more than likely improved lol
anyways lets get into it.........
: note : im not using NPCs in my game so i will use the NPC monster flag for my melee attack
OK firstly i had to make 2 hurt monster scripts, i made mine monster_hurt and monster_hurt1.
Go ahead and make a duplicate of the monster hurt script in the common folder called monster_hurt1
then in your project settings add that script as monster_hurt1 and define it as SCR_HANDLE_MONSTER_HURT1
We the need to point to this in the banks. locate Bank1C and near the top you will fine the player hurt and monster hurt stuff. make it look like this to point to our new monster_hurt1 script when needed.
these can be then adjusted in the monster_hurt scripts in the COMMON folder to take however many hit points for the monsters you desire with your weapons. most moster scripts will have the necessary requirements to do this i think.
the code needed to adjust damge taken is below
if you want to take 3 damage then use 3 of those lines together.
this will override the health in the monster details if u have the health set at 3 which i do. but the melee will still take 3 hits to kill the monster
Next step is to set up object collisions to point to both scripts. so locate your doHandleObjectCollisions and find this code, mine starts at line 81 but look for the start of weapon collisions
you need to make 2 versions of this section so do that first with a commented out line between them so you know which is which.
at the top of that we have our object flags. LDA #%10000000 is the NPC flag that iv re named to melee in the project settings
and LDA #% 00001000 is the projectile/player weapon flag so make sur eyou have checked what flag you are using and then the corresponding bytes on the scripts need to be changed accordingly.
heres my finished version of the object collisions below.
the labels are the pointers to which routine is for what attack - melee and notmelee, projectile and notprojectile. The doHandleHurtMonster and doHandleHurtMonster1 point to which script you use for what health for each attack!
and thats it.... i think
feels good to give back to the community haha
thanks to everyone whos helped me so far
