Hi guys
The script indicates that the animation should happen when the player is close to the item (trap floor),
however the animation only occurs when the player is away from the item.
It's something I can not explain, the script is executed, the sound is heard, the prompt appears, but the animation is not executed until the player away from the item, (>100).

+ Code Snippet

function trap_floor_init(e)
end 

function trap_floor_main(e)
	SetAnimation(0)
	--PlayerDist = GetPlayerDistance(e)
if GetPlayerFlatDistance(e) <= 100 and GetAnimationFrame(e) == 0 then  
	--SetAnimation(0)
	PlayAnimation(e)
	PlaySound(e,0)
	Prompt("Frame = " ..GetAnimationFrame(e) .." plrDist = " ..round(GetPlayerFlatDistance(e),1)) 
end	
end --main

function GetPlayerFlatDistance(e)
  tPlayerDX = (g_Entity[e]['x'] - g_PlayerPosX)
  tPlayerDZ = (g_Entity[e]['z'] - g_PlayerPosZ)
  return math.sqrt(math.abs(tPlayerDX^2)+math.abs(tPlayerDZ^2))
end

function round(num, idp)
  local mult = 10^(idp or 0)
  return math.floor(num * mult + 0.5) / mult
end

Note: I've tried all the commented lines, and it does not make the difference.
Using "GetAnimationFrame(e) == 0", because the idea is start hurting player, when frame count reaches >=58.
I've all the complete script, anyway I decide to short it, just for isolate the issue.

any ideas?

Thanks in advance.

@3com good question. I have similar issues with all my animated characters - when you approach the sound plays and only when you step away from character does the animation play - as opposed to sound and animation simultaneously. I thought it was just me (I struggle with scripts) but was happy to let it ride for now as I am far from publishing. Will be looking at this closely.

I thought that it could have been because i use an animation call in the init stage and then in the main, when player dist = whatever, change animation to what ever and play audio. I understand that yours is not a character but it would appear that our issue is similar.

+ Code Snippet

function anim_1_init(e)
SetAnimationFrames(---,----) ---animation character will spawn doing
 LoopAnimation(e)
end

function anim_1_main(e)

PlayerDist = GetPlayerDistance(e)
 if PlayerDist < 150 then
 SetAnimationFrames(---,----) ------different animation call
   LoopAnimation(e)
  if g_Entity[e]['activated']==0 then
   SetActivated(e,1)
   PlaySound(e,1)
  
  end 
 end

PlayAnimation and PlaySound both constantly call so you need to set a toggle.
if g_Entity[e]['animating'] == 0 then
Would be the usual choice as it automatically resets back to 0 when its finished playing (you need to set it to 1 or whatever you like during the play though)

Thanks a lot smallg!

Now it works.
Often forguet that in a game, the code are constantly looping.

trap_floor.lua

+ Code Snippet

local damage = {}

function trap_floor_init(e)
	damage[e] = 50
end 

function trap_floor_main(e)
	SetAnimation(0)
	PlayerDist = GetPlayerDistance(e)
if PlayerDist <= 100  and g_Entity[e]['animating'] == 0 then 
	g_Entity[e]['animating'] = 1
	PlayAnimation(e)
	PlaySound(e,0)
	HurtPlayer(e,damage[e])
end	
end --main
