Set Vehicle Max Speed

[nwmafia]

I want a script to be able to set the max speed of a vehicle based on it model number. (example of model number for Bufallo = 402).

I want this script to be based on km/h. If you know where I can find a script like this, it would be appreciated. If not, if someone could teach me how to script this, it would be ideal as well. Thanks.

You can either use onClientRender and check if vehicle's speed goes higher than the maximum you want ( should use a table for these things, if it's multiple vehicles ) and set it to the maximum until the player lets velocity go down ( I think this is not efficient - it might lag - and it's harder ) or use handling.

[nwmafia]

I don't want to keep track of their speed, I want to set the limit of speed a vehicle can go, let's say the Buffalo goes 180km/h, I want to limit to 140km/h.

[Anderl]

And what did I just say?

[nwmafia]

I was asking how to make such script, since I don't know how...

[Castillo]

I'm not sure, but maybe you can use the handling functions:

setVehicleHandling 

[myonlake]

I'm not sure, but maybe you can use the handling functions:

setVehicleHandling 

That's alright, but I think this is better since he wants to change all the Buffalos handling

setModelHandling

I was asking how to make such script, since I don't know how...

And I said how to do it, you just need to search for the right functions. It ain't hard.

The code that Wiki showed me, doesn't work..

That wouldn't work, because "onResourceStart" has no player argument.

It still won't work because there's no source neither there is a "carModel" variable.

[myonlake]

That's the same code as nwmafia's. I don't see any outstanding difference there.

[Blaawee]

so what is the right to do ?

[myonlake]

To be honest, I don't know why the model handling switch didn't work... probably it did and nwmafia is blind or then MTA is bugged and should be reported in the Bug Tracker. I think you should try using setVehicleHandling instead for now, that works perfectly at least.

[nwmafia]

The handling did not work, just to make sure it didn't work, I changed the velocity and acceleration to 2000 ... But anyways, clearly no one can help me.

[TAPL]

The code work if you create the vehicle after using the code NOT before.

This means, if you use the code and set the maxVelocity to 100, any new created vehicle will have maxVelocity = 100 if you again set maxVelocity to 200 any new created vehicle will have maxVelocity = 200 but the previous vehicle will stay at maxVelocity = 100.

So this code does't change the current created vehicle but the newer.
