Neon Carball DirectX Scripts

[MAB]

I saw amazing things at a server called Neon Carball ( mtasa://176.9.73.171:13337 ).

The scripter is inactive so i couldn't ask him how did he made the mini map and the reply thing.

So please, enter that server and take a look and if you know how it was maden, please, share.

To make a minimap like that you'll need to convert their 3D space onto a 2D plane, if you do some Google searches I'm sure you'll find quite a bit of information on how to accomplish this.

As for the replay, I wrote something similar for testing purposes a while ago. Basically, what you need to do is store the position and rotation of the vehicle in a table. You then loop through this table.

You can check out my testing script if you want, do note however that I wrote this a long time ago and never finished it. Nor do I intend to.

Also, this was merely written for testing purposes. As such, this code has not been refactored and is not optimized in any way shape or form.

How to use:

1. Start the resource.

2. Start race, and pick whatever map you want.

3. The recording starts once the race state is changed to "running".

4. It records for 15 seconds.

5. Use the command /startreplay to start the replay. (Go back to the starting position first)

i need to learn how not to use other scripters resources and i don't understanf your script

[TAPL]

I guess Dealman just wasted his time trying to help you. Seriously you should consider rereading what Dealman wrote and carefully.

[Dealman]

I wouldn't necessarily call it wasting my time, I'm sure other readers might find it useful.

@Amir:

If you truly wanna learn not to use other people's scripts, you should start searching for information. Programming and scripting isn't much other than trial and error, really.

For example, you need to plan ahead before you start scripting. Use both these forums, the MTA Wiki and Google for inspiration, even if the tutorial you're looking at is written for C++ or whatever language - you can always adapt it for Lua.

For example to make a replay system think of it like this;

1. You need to capture the behaviour of a vehicle;

1a) You'll want to save the position of the vehicle

1b) You'll want to save the rotation of the vehicle

1c) You'll want to save the velocity of the vehicle (may not be necessary)

Okay so you know this so far - position, rotation and velocity. A quick glance at the MTA Wiki and you'll find these functions do exactly what you want;

getElementPosition 
getElementRotation 
getElementVelocity 

2. Now that you have the necessary functions to record the behaviour of a vehicle; how do we go about doing this?

2a) Timers. Would a timer be a logical choice? No, because it has a minimum interval of 50ms - which may result in a choppy replay.

2b) What would the best option be for smooth and accurate capture? Obviously, onClientRender comes to mind since at 60 FPS you'll be executing the code every ~16ms.

So now you know when to capture these values, but where do we store all the values? Obviously inside of a table - you can either use one table or like I did, a separate table for every value(position, rotation and velocity).

How do we store values inside of a table? If we didn't know this, we'd head onto Google and search for "lua insert value table" or something similar - immediately we'd find that this is what we want;

table.insert(theTable, theValue) 

----

This is the kind of way you have to go about doing things. You might also want to write it down, sort of like brainstorming. You'd be surprised how many professional programmers do brainstorming before they go ahead and find a solution that fits their needs.
