Scripting Tutorial 2 - MTA Snow

[ijsf]

NOTICE: THIS TUTORIAL MAY BE OUTDATED! PLEASE READ: http://forum.mtasa.com/viewtopic.php?f=91&t=22270

Following last week's scripting tutorials on user created portals, we've just published a new tutorial covering MTA Snow.

The tutorial shows you how to create special entities, how to make them look and fall like snow.. with some imagination of course.

Head over to the Tutorials section to see!

[Sprinter]

Don't know if it's just me but I can't see all of the script text.
Screenie:



I'm using FF btw.

You should probably use a newline for comments, like it was last time. I'm sure it will be fixed soon.

Nice tutorial by the way. Not quite what I expected, but it shows once again the power of Lua and MTA.

.edit.
The link to the complete script results in a 404.

Don't know if it's just me but I can't see all of the script text....

I use opera and when I get sucha problem I go to Tools/Preferences/Web Pages/Fit to width.... i dont know which browser u use, but try something like that

[Talco]

Good tutorial, but...
the link for the complete script dont work (not found) http://www.mtasa.com/downloads/script2.lua

i think this tutorial was to show the object manipulation which you will have also seen with the hay bails in the xmas vid

Talco is right, downloading the scripts give me a "404 - Not Found" error.

Also, for viewing the comments: you cannot see them, but they are copied when you select the whole page .

Lol will this work?:

[lua]addCommandHandler ( "teleport", "tele_TeleCommand" )

function tele_TeleCommand ( player, commandname, x, y, z )
outputChatBox ( getClientName ( player ) .. " was teleported." ) --Thx eAi for telling me about the space
setElementPosition ( player, x, y, z )
end[/lua] Probably not but at least I tried to make something.

Also about the outputChatBox function, can i make the text I put in the chatbox purple or red (or wutever color)?

[eAi]

Yes, that looks like it'll work, except you'll want a space before 'was', i.e. " was teleported".

As for colors, yes, you can use them, just by adding the RGB value as arguments. The full definition for outputChatBox is:

[lua]bool outputChatBox ( string text, [ element visibleTo=getRootElement(), int r=255, int g=255, int b=255 ] )[/lua]

[Y_Less]

How much bandwidth does this thing use as repeatedly setting a load of entities positions for loads of players can't be great. Also, wouldn't:

if not px or not py or not pz then
snowing = false
return

stop the snow if the player was on one of the axis? I.e. stood right in the middle of the world where X and Y would be 0.0, thus evaluating to false?

[iam2noob4u]

unless lua knows/sees the diffrence between 0 and 0.0000000 i think you're right. besides, if my teleport 'script' (rather to be called a very small code) will work with the first release, you could try it, and teleport to any position with either x, y, or z as 0

also the correct usage of outputChatBox would be:

[lua]outputChatBox ( getClientName ( player ) .. " was teleported." , 255 , 43 , 43)[/lua]

right?

btw sorry for asking so much time that could be spend on development

[lil Toady]

color is not required, if it's not set, mta uses default color

here:

Line number On/Off | Expand/Contract | Select all

bool outputChatBox ( string text, [ element visibleTo=getRootElement(), int r=255, int g=255, int b=255 ] )

all the stuff in [] brackets is not required

[iam2noob4u]

i meant: "if i use colors, this is the right way to use it"

i should have been clearer.

[Brophy]

[lua]-- outputChatBox ( "What you wanna say", visibleto, r, g, b )

-- Example

root = getRootElement ()
outputChatBox ( "Sniff me!", root, 255, 80, 60 ) [/lua]

Sorry i know its not a 'script' question, but what music was that?

No, it would only be false if one of the values were either false or nil.
