Please post your comments about tutorial 8 scripts below. Thanks. 8)

The two seperate scripts for the ion cannon and nuke are posted below respectively. All of these two script's creation/commenting/video recording was done by me. So if you have any questions I'll be more than happy to answer them for you. ENJOY!

Tutorial 8a: Ion Cannon

:!: :!: :!: :!: :!: :!: :!: :!: :!: :!: :!: :!: :!: :!: :!: :!: :!: :!: :!: :!:

Start defining varibles, including a players array

root = getRootElement () 
players = {} 
  
outputChatBox ( "Ion cannon by Ransom" ) 
ion_rotx = 0 
ion_loops = 0 
ion_explosionTimer = 0 
ion_cannonActivated = false 
ion_cancelActivation = false 
ion_beamSize = 5 
ion_beamFlareSize = 5 
players = getElementsByType ( "player" )

Give all players on the server access to the weapons

addEventHandler ( "onResourceStart", root, "ResourceStartIonCannon" ) 
function ResourceStartIonCannon ( name, root ) 
if name ~= getThisResource() then return end 
    for k,v in players do 
    -- for all players in the "players" array 
    bindKey ( v, "f", "down", "placeIonCannonBeacon" ) 
    -- bind the key f for triggering the ion cannon 
    end 
end 
  
addEventHandler ( "onPlayerJoin", root, "ionPlayerJoin" ) 
function ionPlayerJoin () 
    bindKey ( source, "f", "down", "placeIonCannonBeacon" ) 
    --if a player joins after the resource loaded, bind their f key to trigger the ion cannon also 
end

When the ion cannon key (f) is pressed, show the mouse cursor that will allow the triggering of the onPlayerClick function

function placeIonCannonBeacon ( player, key, state ) 
    if ( ion_cannonActivated == false ) and ( ion_cancelActivation == false ) and ( nuke_cancelActivation == false ) 
    and ( nuke_cannonActivated == false ) then

Woot. First to reply. Finally! Anyways, would this be possible to do without click. Say, you goto Area 52 and click on a spot on map or something. if you get what I mean.

Well theres many different ways you can trigger something to occur with Lua. For a future version, yes I was hoping to be able to click on a map, get player details, and confirm a launch to their location. Could maybe cycle through a players list, type players name... thousands of possibilites. Its sometimes hard to have a concrete answer though. It depends on your ability to manipulate the functions MTA has provided to get what you desire. Such things like Aeron makes (A.I. sam site rockets, hay climb tower) seem impossible at first, but it can be done.

Although the MTA team has provided the functions and events, they are amazed themselves sometimes by how we coordinate them with scripting and come up with impressive results such as the imitation of WMDs in this video. eai was particularly pleased with this one as well since he is also a big C&C fan. I hope to perhaps make a mode to use these weapons in a team game or something for the future. We'll see depending on my time. I'd probably produce it this summer if anything.

Very cool! Best tutorial subject so far :D I have 1 question can you make a explosion like this shape?

nukebc3.jpg

Yes, that was the shape I was going for. If you read the code you'll see I did it in this way because I'm strecthing explosions to the GTA limit pretty much. You could make it more expansive but the completion time would be slower since you can only do so many explosions at once. I'll try to make a splash pool of explosions on the ground radius before I start the cloud but it may look too slow or glitchy. If I do, it should resemble your picture pretty well. The width of the middle part could be imitated more if you expand the radius of explosions as the nuke goes upward. Even if I can't make a better explosion cloud, when the flash goes off for the nuke explosion, I'll be defining an instant kill radius anyhow. Its not completed yet, but the visuals are pretty accurate already.

Also note for this same reason that the two weapons can NOT be launched at the same time. Many explosions would occur sporadically between them and ruin the visuals. The exact explosion limit you ask? From my testing and timing of these weapons as I recall the max stretch was 60 explosions at once (from the explosion to the time the smoke animation clears which takes considerably longer).

Can you make a Scud Storm to? like in C&C Generals

like this:

Generals-GLA-ScudStorm.jpg

Yep. Matter of fact it would just be a matter of adding more missile objects and more timings (for seperate missiles/explosions to create seperate heights). It would require you to define certain explosion locations so the impact of each appears to explode. Plus, if you wouldn't want them to keep the same shape you'd use random varibles between two numbers much like I did for the explosion cloud for my nuke. It would be considerably harder to script because it would be long unless you were advanced enough to use looping really well to overwrite varibles and such.

I have made "ion cannon" in sa-mp, but it's far not that realistic. Thanks for this tutorial.

Before this?! :shock:

I just thought of an idea. It must be possible to make some kind of DBZ game-mode with this :lol:. That in combination with Low Grav could work. Just make the ION blast smaller and come out of the player's hand. Maybe I should learn scripting and put all these tutorials to good use :P

Yeah. I has made advanced mode, which mixes CS, UT and some other teamplay games. I have made lots of maps, voting for the next map, cs_, de_, dd_, es_, as_, tdm_ and ctf_ modes and a HUGE shop with all the weapons and some extra items. And ion cannon was one of them. :roll:

The proof is in the pudding, but since BrophY ate all the pudding, a screenshot will suffice.

I actually made a script a while back where you could jump real high, glide on air, teleport around and shoot fireballs using key combinations (think hadooken).
