Train stuff

[Captain Cody]

I have created a train script, but for other people on the server, the carts appear on different tracks. For the driver they appear on a single track. How would I fix this "If even possible"

     
function startScript () 
Train = createVehicle ( 538, 2765.2949, 508.41016, 9.864749 ) 
Cart = createVehicle ( 570, 2765.2949, 538.41016, 9.864749 ) 
Cart2 = createVehicle ( 570, 2765.2949, 590.41016, 9.864749 ) 
Cart3 = createVehicle ( 590, 2765.2949, 620.41016, 9.864749 ) 
setTrainDirection(Train, true) 
setTrainDerailable(Train, false) 
setTrainDerailable(Cart, false) 
setTrainDerailable(Cart2, false) 
setTrainDerailable(Cart3, false) 
setTimer ( checkdistance, 100, 0) 
setTimer ( checkdistance2, 100, 0) 
setTimer ( checkdistance3, 100, 0) 
end 
  
function checkdistance () 
vehicle1x, vehicle1y, vehicle1z = getElementPosition ( Train ) 
vehicle2x, vehicle2y, vehicle2z = getElementPosition ( Cart ) 
local distance = getDistanceBetweenPoints2D ( vehicle1x, vehicle1y, vehicle2x, vehicle2y ) 
local speedT2 = getTrainSpeed ( Train ) 
if distance > 19 then 
setTrainSpeed(Cart, speedT2+0.01) 
else 
if distance < 19 then 
setTrainSpeed(Cart, speedT2-0.0105) 
else 
if distance < 18 then 
setTrainSpeed(Cart, speedT2-0.015) 
end 
end 
end 
end 
  
function checkdistance2 () 
vehiclegx, vehiclegy, vehiclegz = getElementPosition ( Cart2 ) 
local distancea = getDistanceBetweenPoints2D ( vehicle1x, vehicle1y, vehiclegx, vehiclegy ) 
local speedT2 = getTrainSpeed ( Train ) 
if distancea > 40 then 
setTrainSpeed(Cart2, speedT2+0.01) 
else 
if distancea < 40 then 
setTrainSpeed(Cart2, speedT2-0.0105) 
if distancea < 39 then 
setTrainSpeed(Cart2, speedT2-0.015) 
end 
end 
end 
end 
  
function checkdistance3 () 
vehiclefx, vehiclefy, vehiclefz = getElementPosition ( Cart3 ) 
local distancea = getDistanceBetweenPoints2D ( vehicle1x, vehicle1y, vehiclefx, vehiclefy ) 
local speedT2 = getTrainSpeed ( Train ) 
if distancea > 61 then 
setTrainSpeed(Cart3, speedT2+0.01) 
else 
if distancea < 61 then 
setTrainSpeed(Cart3, speedT2-0.0105) 
if distancea < 60 then 
setTrainSpeed(Cart3, speedT2-0.015) 
end 
end 
end 
end 
  
function traincruise (playersource) 
theSpeed = getTrainSpeed(Train) 
trainTrack = getTrainTrack(Train) 
local thespeeda = getTrainSpeed(Train) 
outputChatBox ( "Train set to cruise at :" ..thespeeda.." MS", playersource ) 
TrainTimer = setTimer ( setSpeed, 300, 0) 
end 
  
function setSpeed () 
setTrainSpeed (Train, theSpeed) 
end 
  
function cancelcruise () 
killTimer (TrainTimer) 
outputChatBox ( "Train cruise disabled.", playersource ) 
end 
  
  
addCommandHandler ( "traincstop", cancelcruise ) 
addCommandHandler ( "trainc", traincruise ) 
addEventHandler ("onResourceStart", getResourceRootElement(getThisResource()), startScript)

Any one have any ideas on how to fix this?

[IIYAMA]

wait for 1.6... or use 1.6 beta.

1.6 will enable functions to control that.

I have the same problem with: https://forum.multitheftauto.com/viewtopic.php?f ... ain+script

[Captain Cody]

Ah ok thanks.

1.6 will only provide these two functions currently:

bool setTrainTrack(vehicle train, int track) 
bool getTrainTrack(vehicle train, int track) 

Although you can control which track to spawn in you can't control where on the track your train will spawn currently. Take the two main tracks as an example if you are in San Fierro and switch the tracks from there you'll end up at a random location on the other track. These two resources provide sample code to illustrate the issue as well as temporary solutions to them: GTWtrain and GTWvehicles.

What you can do is to position all cars you want to attach to your engine after your engine before attaching them by using math.sin and math.cos and the distance 20. This seems to work for up to 15 cars, more than that could still cause them to end up in different tracks. You can also prevent the cars from streaming out, which you would need to do anyway for trains longer than 8 cars as streamed out train elements tends to end up in a different track.

Well if you stay near the train there is no issue, the only issue is when someone leaves the train it steams out client side "I'm assuming", when they go back to the train for them some carts are on different tracks but for the person who is at the train all the carts are on the same tracks.
