Minecraft sentry Gun

[casakim]

I just finished building my sentry gun which has 6 dispensers but when I get hit, i always got a life and a half left. So I was thinking about making a fire arrow and does it do more damage or something? If not is there a way making dispensers do more damage than it's suppose to do?

[GRgaergaergaergerag]

hm... CSB, I don't know. fire arrows is a good idea, but this more damage thing...

[Soldier of God]

post some screenshots?

Use lava to make flaming arrows.

[Heartview]

Except flaming arrows dont do more damage. /fp

And I cant search it now as I dont have the right files, but I do believe that once an arrow is fired, it counts as an entity, kinda like TNT. You will want to take that into consideration if you plan on modding it.

I was going to suggest modding arrow damage.
If not then is your sentry gun going at maximum speed?
I'm pretty sure flaming arrows will set you on fire...Do they not?

Flames on arrows are nothing more than aesthetic. They add no damage, and no fire spread is there.

Um, maybe if youre in your house... Make a lava lamp, but without glass. Just let lava fall. And behind the sheet of falling lava make 2 or 3 sentry guns. And then place some step triggers, make your floor of wood triggers. Make one switch hidden that disables the trap, and make one fake that enables it that every wooden floor switch fires the dispensers. That is the perfect trap.

QQ Always thought they could spread fires to what they hit.

if your going to mod it inspect EntityArrow.java

theres it, you can change it timing out ect.
jsut have a look and change the orange values.

[GRgaergaergaergerag]

...or make more dispensers?

...or make more dispensers?

it wont have the same effect now will it?

[legocjman]

If you fire an arrow through a lava fall it supposedly makes a flaming arrow. I don't think it changes the damage though.
