I am working on a animated tank,
First i am going to try is make the Tracks spin go forward.
This is what i got so far, but the tracks animate and turns but not going forward. any help with this.

+ Code Snippet


-- LUA Script - precede every function and global member with lowercase name of script + '_main'
-- Door Prompts 'Closed' can be opened


function tank_init(e)
end
	 
function tank_main(e)
 PlayerDX = g_Entity[e]['x'] - g_PlayerPosX;
 PlayerDY = g_Entity[e]['y'] - g_PlayerPosY;
 PlayerDZ = g_Entity[e]['z'] - g_PlayerPosZ;
 PlayerDist = math.sqrt(math.abs(PlayerDX*PlayerDX)+math.abs(PlayerDY*PlayerDY)+math.abs(PlayerDZ*PlayerDZ));


  SetAnimation(0);
  SetAnimationSpeed(e,100)
  
  
  if g_Entity[e]['animating'] == 0 then
  PlayAnimation(e);
  LoopAnimation(e);
  g_Entity[e]['animating'] = 1
  end
  MoveForward(e,150);
  RotateY(e,10);
    
 end

Are you using some trigger to run script?
You are calculating PlayerDist, but you are not using it, ie: If PlayerDist<100 then....
Non expert scripter, but till one coming, ago ttime I had writted this one for move jeep, but I'm working with StartTimer(e).

+ Code Snippet

-- LUA Script - precede every function and global member with lowercase name of script + '_main'
-- jeep

function jeep_init(e)
  GravityOff(e)
  CollisionOn(e)
  StartTimer(e)	
end

function jeep_main(e)
  
  PlayerDX = g_Entity[e]['x'] - g_PlayerPosX;
  PlayerDY = g_Entity[e]['y'] - g_PlayerPosY;
  PlayerDZ = g_Entity[e]['z'] - g_PlayerPosZ;
  PlayerDist = math.sqrt(math.abs(PlayerDX^2)+math.abs(PlayerDY^2)+math.abs(PlayerDZ^2));
 
  GravityOff(e)
  CollisionOn(e)
  ntimer=GetTimer(e)
  Prompt(ntimer)

if ntimer <= 65000  then
  MoveBackward(e, 100) 	 
else
  IsInmobile = 1
end

if ntimer > 90000 and ntimer <= 180000 then 
  IsInmobile = 0
  MoveBackward(e, 100) 
else
  IsInmobile = 1
end
end

so, you can control when move/stop animated tank. Although mine is not rigged (animated), since jeep model is not mine.

I found out that if i set collision off in the fpe file, then the moveforward command works, and the tank goes forward.. Bu not when i set collision on.
I tried mode 1, 2,3 etc etc. but it get stuck on the ground.

Maybe you has to play with collision off/on via script, in order to fit yours needs.

well i got it moving forward, with collision off, but how do i made it stop. my code is in a loop.
i don't know much of coding , so i have been trying for a couple of hours now, but i don't get it.
any help Please...
The code i've got so far:

+ Code Snippet

-- LUA Script - precede every function and global member with lowercase name of script + '_main'
-- Door Prompts 'Closed' can be opened


function tank_init(e)
end
	 
function tank_main(e)

 PlayerDY = g_Entity[e]['y'] - g_PlayerPosY;
 PlayerDZ = g_Entity[e]['z'] - g_PlayerPosZ;
 PlayerDist = math.sqrt(math.abs(PlayerDX*PlayerDX)+math.abs(PlayerDY*PlayerDY)+math.abs(PlayerDZ*PlayerDZ));

 steps=MoveForward(e)
  SetAnimation(0);
  SetAnimationSpeed(e,125)
  steps=(-75)
  
  --RotateY(e,0);
 
  
  IsInmobile = 0
  
  if g_Entity[e]['animating'] == 0 then
  PlayAnimation(e);
  
  g_Entity[e]['animating'] = 1
  LoopAnimation(e);
  

  end
  MoveForward(e,steps);
  

    
    
 end

Thanks

depends why you want it to stop
what are you trying to make the tank do? or is this only to test the animation?

you will need to give the moveforward command a condition

something like
if GetPlayerDistance(e) > 500 then
RotateToPlayer(e)
MoveForward(e,100)
end

note you seem like you need to add
Fixnewy = 180
in your fpe file if the tank is facing the wrong direction

Hello smallg,
What i want is to test all my anims and try to make a tank more alive.
Follow a path and when the player is in range rotate at player and shoot. etc
I have anim frames from 0-360 both tracks turning. 361 to 720 right track, 721 to 1080 left track.

I changed the code a bit and now it is following the player the only thing is that the animtion plays when the player is in range, and when i walk away the animation stops.
It should be the other way around.
Here is my code.

+ Code Snippet

-- LUA Script - precede every function and global member with lowercase name of script + '_main'
-- Door Prompts 'Closed' can be opened


function tank_init(e)
end
	 
function tank_main(e)
 PlayerDX = g_Entity[e]['x'] - g_PlayerPosX;
 PlayerDY = g_Entity[e]['y'] - g_PlayerPosY;
 PlayerDZ = g_Entity[e]['z'] - g_PlayerPosZ;
 PlayerDist = math.sqrt(math.abs(PlayerDX*PlayerDX)+math.abs(PlayerDY*PlayerDY)+math.abs(PlayerDZ*PlayerDZ));

 
  SetAnimation(0);
  
  SetAnimationSpeed(e,125)
 
  
  --RotateY(e,0);
  
  if GetPlayerDistance(e) > 500 then
 RotateToPlayer(e)
 MoveForward(e,100) 
  PlayAnimation(e);
  
   
 if GetPlayerDistance(e) <= 500 then
 StopAnimation(e)
    --end
	
	
  
  --if g_Entity[e]['animating'] == 0 then
  --
  
  --g_Entity[e]['animating'] = 1
  --PlayAnimation(e);
  
  --end
  end
  
 end


    
    
 end

many Thanks
Harry

You didn't close the first if distance statement before the next 1, edit; that second statement is never true while inside the first - it'll never be greater than 500 AND less than 500

Also try using loopanimation instead of playanimation

+ Code Snippet

function tank_init(e)
end
      
function tank_main(e)
 
  SetAnimation(0);
  SetAnimationSpeed(e,125)
   
  if GetPlayerDistance(e) > 500 then
 RotateToPlayerSlowly(e,1)
 MoveForward(e,100)
  LoopAnimation(e);
   
 elseif GetPlayerDistance(e) <= 500 then
 StopAnimation(e)
  end
 
 end

try that

Ive got the basic working. if it follows then the tracks animate and stops.

Is it possible to let the tank follow waypoints?
And how do i set that up?

I fear that currently only the characters follow a waypoint.

For this reason I used the time instead of a waypoint in the above script.
I used the river as a waypoint, and measured the time it took the raft to reach a bend, then I used this measure to rotate the raft conveniently and so on, until the end of the river. Although this is not a very nice way, but it is achievable.

as 3com said you can make your tank a character and then it will follow waypoints with a script that includes the following code

EntObjNo = g_Entity[e]['obj']

if ai_soldier_state[e] == "patrol" then
  if ai_soldier_pathindex[e] == -1 then
   ai_soldier_pathindex[e] = -2
   CharacterControlArmed(e)
   PathIndex = -1
   PathPointIndex = -1
   pClosest = 99999
   for pa = 1, AIGetTotalPaths(), 1 do
    for po = 1 , AIGetPathCountPoints(pa), 1 do
     pDX = g_Entity[e]['x'] - AIPathGetPointX(pa,po)
     pDZ = g_Entity[e]['z'] - AIPathGetPointZ(pa,po)
     pDist = math.sqrt(math.abs(pDX*pDX)+math.abs(pDZ*pDZ))
     if pDist < pClosest and pDist < 200 then
      pClosest = pDist
      PathIndex = pa
	  PathPointIndex = po
     end
    end -- po
   end -- pa
   if PathIndex > -1 then
    ai_soldier_pathindex[e] = PathIndex
	ai_path_point_index[e] = PathPointIndex
	ModulateSpeed(e,1.0)
	SetCharacterToWalk(e)
	ai_path_point_direction[e] = 1
	ai_path_point_max[e] = AIGetPathCountPoints(ai_soldier_pathindex[e])
   end   
  end
  if ai_soldier_pathindex[e] > -1 then 
   ai_patrol_x[e] = AIPathGetPointX(ai_soldier_pathindex[e],ai_path_point_index[e])
   ai_patrol_z[e] = AIPathGetPointZ(ai_soldier_pathindex[e],ai_path_point_index[e])
   AIEntityGoToPosition(EntObjNo,ai_patrol_x[e],ai_patrol_z[e])
   tDistX = g_Entity[e]['x'] - ai_patrol_x[e]
   tDistZ = g_Entity[e]['z'] - ai_patrol_z[e]
   DistFromPath = math.sqrt(math.abs(tDistX*tDistX)+math.abs(tDistZ*tDistZ))	
   if DistFromPath < 50 then
	if ai_path_point_direction[e] == 1 then
	 ai_path_point_index[e] = ai_path_point_index[e] + 1
	 if ( ai_path_point_index[e] > ai_path_point_max[e] ) then
	  ai_path_point_index[e] = ai_path_point_max[e] - 1
	  ai_path_point_direction[e] = 0
	 end
	else
	 ai_path_point_index[e] = ai_path_point_index[e] - 1
	 if ( ai_path_point_index[e] < 1 ) then
	  ai_path_point_index[e] = 2
	  ai_path_point_direction[e] = 1
	 end		
	end
   end
  end

haha nice, that was the initial idea for my script but i changed it after a few minor issues with the camera control (no easy way to control the camera angle being the main issue), looks good there though
