I tried adding this code from the OP in 2 player platformer after IsPlayerLethalInvincible and it didn't account for monster health (which I set to 2).

if you made a modification that doesn't work. Please share your modified script. Else there is no way we can tell you where is your error.

HandleObjectCollisions_DC.asm
starting at lines 232:

playerWasNotHurtDuringCollision:
;; dale_coop: player in X ?
LDA Object_vulnerability,x
AND #%01000000 ;; is he lethal invincible?
BNE isLethalInvincible
JMP notLethalInvincible
isLethalInvincible:

LDA Object_y_hi,x
STA temp1
CreateObject temp, temp1, #OBJ_MONSTER_DEATH, #$00, currentNametable ;; create "splat"
LDX tempxx

notMunsterDeath:
;;; ordinarily we'll want to destroy the instance.
DeactivateCurrentObject
;; incrase score, you killed a monster
PlaySound #SND_MONSTER_DEATH




That's what it looks like. It doesn't account for the monster's health it's just an instant kill. Thank you for your help.

Could you share the entire script? I'll check why it doesn't work in your script.

Small off topic, when you write/copy/paste script on the forum, use the [ code ] tag, around your code. It will make it easier to read (and easier to copy/paste)

Re: Jump On Hurts (modified jump on kills script)

Post by dale_coop » Tue Jan 14, 2020 4:25 pm

But this one is not the "HandleObjectCollisions withJumpOnKills" asm script... as the original post of this topic.
Yours it the normal HandleObjectCollisions the one where you CAN NOT jump on monsters (not implemented in that script).

Try assigning the HandleObjectCollisions_DCwithJumpOnKills.asm script (in the "ModuleScripts\MainScripts\SimplePlatformer" folder) to the "Handle Object Collisions" element in your "Project Settings > Script Settings", and try again the modification...
if yoru modification doesn't work, share again your new modified script. I'll take a look.
