-orb-'s Wiremod Tutorials

[Little Green Man]

Thank you SOOOOOOOOOOOOO much for these tutorials, especcially for the normal and expression gate versions of the automated turret. I seriously didn't get Trickys one as i had an old version of wiremod (have now updated) which didn't work the same as his. Anyway, I think these are the best video tutorials on here. TY.

Tutorial about Expression Gates rocks!

-orb-, maybe you know how the satellite dish works? The best I got is aiming the transferrer to the satellite dish and getting a green light from the transferer, but nothing else. I don't see any options to wire it. I don't know what is it good for lol.[/b]

I got the same opinion about the tutorial and the satellite dish!
I just thought about a lot of complicated things i use in php, that i cant use in expression gate before i saw your tutorial!

oh yeah what is the formula needed to make it aim at the head not the feet?

Thanks for the support again guys!

K: Thanks for the support Syranide. Definitely make it so you can have like 200 chars or something. Trust me, this isn't just speculation, I've already had expressions where I had to split things up into two lines since it was too long.

Er, no idea how to use the satellite dish guys. I'm way behind you on that one, I've never even used the data transferrer, or the other thing in that category. It seems pretty pointless to me. I don't really know what the purpose is. Maybe if I knew, I'd know why you guys use it.

Formula to make it aim at the head:

Okay, first off you need to make the beacon sensor output distance.

We're going to use trigonometry to determine the angle difference based on the distance.

So next thing you need to do is find out how far it is from someone's head to the ground. Don't use an NPC or someone else, because your head camera isn't perfectly placed in your head (generally). Instead, spawn a prop at head level in front of you and use the measuring stick (if you have it installed) or a ranger to find the distance to the ground. Save this distance.

Let's assume the height is 50 (even though it likely isn't). This is the vertical change we need to make.

So we have our triangle of change:



So the trigonometric formula would be that the sin(the angle we need to compensate for) = (Height/Distance)

or

Angle diff = inversesin(50/Distance)

However, I don't know how to do inverse sine with the expression gate, so you'd either have to ask Syranide (the creator of the Expression gate) what the syntax is for inverse sine or you'd have ot create a separate inverse sine math gate and do this outside of the expression gate.

Sorry for making it sound so complex, it's really just a math formula with trig to find the difference in the angle that we have to compensate for. Maybe if Syranide tells us how to do inverse sine I'll make a tutorial on making it shoot for the head.

sorry they are a bit vague in name im gonna make a tut explaining each one which then orb will inevitably bring out a better al excompassing one for a sattellite and ground dish array.

you know it.

BTW I found inverse sine on the documentation. Inverse sine is the same as Arc Sine (asin). So I can just use asin(numbers)

I'll make a tutorial sometime soon. I just got a job as a PC Technician at Circuit City, so I might not be online as much. Wait, what am I saying? I usually wake up at 3 in the afternoon... now i'll just start waking up earlier. I'll prolly be online just as much... lol.

Nice tutorials -orb-

I made an easier way to add height to an angle using the beacon sensor, this just takes a distance and an elevation input, then it uses trig functions to add the height of the target and returns the new elevation value. It can an be easily implemented into your turret contraptions and they won't shoot at the players' feet anymore.
I&#39;ve just made it (it took me about 5 minutes and a little brains) and <strike>I still have to test it, but i&#39;m 90% sure it works.</strike> I tested it and it works

N@Us3r's Sensor Elevation Fixer
I@Distance Elevation
O@FixedElevation
#Change the value of the next variable as it best fits you
HEIGHT = 30
#Don't change the following unless you know what you're doing;)
!Distance -> FixedElevation = 0, end;
FixedElevation = atan(sin(Elevation)+HEIGHT/Distance, cos(Elevation))

Change the HEIGHT value if you need. A tip: don&#39;t make your contraptions aim for the head of the players, or they will be able to easy avoid being shot by crouching. If you&#39;re getting trouble with this or you just don&#39;t understand how it works feel free to ask me.

Hope this helps

EDIT: Just realized (by looking at the documentation again) that the function was called atan and not arctan. I fixed it
EDIT 2: Tested: it works

That&#39;s close to what I did. I used arc tangent. Yours is actually way more complicated than mine.

I already made a tutorial on it, it&#39;ll be online by tomorrow, it&#39;s uploading to revver now.
