Invasion Mod 1.7.10/1.7.2/1.6.4 by unstoppableN

The nexus is the central block of the entire mod. Crafting a catalyst and putting it into the nexus’s item slot will begin to activate it. Once fully activated, it will begin to generate rift flux, a useful resource. There are two modes the nexus can be in:

Invasion Mode

Activated by inserting a regular Nexus Catalyst. Once tapped into a rift to this degree, disengaging is extremely unsafe. It cannot be deactivated. In fact, the block will become unbreakable during this state, though it can be damaged.

You get flux, but the other side of this is that mobs will begin to spawn a certain distance away, attracted to the nexus. Mobs will attack players and, given the chance, the nexus itself. If the nexus ever reaches 0%, the activation is broken and the invasion ends in a nasty way to all living things in the area, so be warned (To clarify, it doesn’t damage any blocks, just living things, and remains afterwards.) A nexus is pretty tough though, and its damage state is highly visible.

Continuous Mode
Activated by inserting a Stable Catalyst, the nexus generates flux much more slowly. Mobs sometimes can attack at night, so be prepared. You can tell by sunset whether the nexus will be attacked that night or not. Over time, the nexus gradually charges up. This results in faster flux generation but attacks by mobs become much stronger. Failing to keep the nexus safe will inevitably cause a partial discharge as the mobs overwhelm it, but successful defenses will allow the nexus to reach higher and higher power levels. The discharge in this state is not enough to harm the player, though. You can control the nexus in this state to some degree with damping agents, including shutting it down if needed, but it’s not instant.

To defend the nexus in continuous mode, you must deal with the mobs who have destabilised the rift and forced their way into the world. Killing enough of them to restabilise the rift will let the nexus safely draw more energy and help you secure the area.

You can also adjust the nexus range to suit your base. The range is roughly the area the nexus influences and the range at which mobs will spawn. By default it is about 60 blocks outward. An op can adjust it by using ?/invasion range [x] as a command. Or you can use a Nexus Adjuster. Don’t worry, the range is very visible on the nexus interface.


Here’s a quick overview of the nexus interface. A catalyst in the left slot will begin to activate the the nexus, progress being the red bar. This nexus is already active and locked in. The slot on the right is where rift flux is generated, along with its progress bar too. Wave number is the current intensity of the attack while nexus level is the the furthest wave this nexus has ever reached. It also tracks the total number of mobs’ demise since it was placed.

Making a nexus involves taking an obsidian block as a base and crafting it with three redstone and a phase crystal
Nexus

To make the important phase crystal needed, you will need one diamond and some redstone. Don’t worry, a nexus is good at generating resources back.
Phase Crystal

The nexus is not a requirement to get lots of invasion mobs spawning. It’s not enabled by default, but you can replace regular random mob spawns at night with as many invasion mobs as you like, and of what type. Mobs will only break blocks if they are actively chasing a player and can be set up to see variable distances. Otherwise, they burn in sunlight similarly to regular mobs. Standby in the future for more behaviours.

To enable this, find invasion_config.cfg’ in your minecraft config folder after running the mod once. You should open it in notepad and you can simply change values and save. For example, change enable-night-spawns from ‘false to true’.

-Mob spawn chance. This is the overall rate of custom mobs spawning.
-Maximum number of mobs existing at once. Minecraft’s default is 70 but you can override this.
-Sight range. This is how far they can see you, in number of blocks.
-Sense range. Similarly, this is how far away they can feel your presence and know you’re there.
-Maximum group size. This up to how many mobs might spawn together in one spot.

With spawn types unchanged, various types of zombies and spiders spawn in place of their basic counterparts. You can change this though, adding any other type of invasion mob and how often they spawn ? for example ALL skeletons with some pig engineers. This is easy to set up in the config file.

Rift Flux

This material is slowly generated by the nexus when it is active and can be used to craft things such as diamonds or infused swords currently. Armor and more items will come. You can also find glowing remnants on some attackers that you can craft together into rift flux.

One use is to craft them into diamonds, though it still takes significant effort given the rate of flux generation.

Rift Flux to various items

You could also use them to make one of several useful items, such as the infused sword.

Infused Sword

This adds a special on-use effect to a diamond sword. Hitting mobs charges it up, which happens quite quickly. When charged, activation by right-click will instantly heal you for 3 hearts. Or when you hold shift for 3 hunger. We’ve found this item really helps in a pinch and helps keep up with a lot mobs. You can also use it anywhere in minecraft.

Searing Bow

When you charge up this bow all the way to it’s end, it will shoot burning arrows to light your foes on fire.

Nexus Adjuster

The nexus adjusters enables players to change the nexus spawn range when the nexus is not active.

Material Probe

An upgrade of the adjuster, with a rick-click the material probe also lets you measure the strength of any block as far as invasion mobs are concerned. The probe also can recover traps without triggered them, so you can move or store them.

Traps
Empty Trap

Kind of an empty frame, you can turn these into different kinds of traps. They are always reusable and quite user-friendly, except the one case where you stand on one. The goal of using these is to help keep area control despite being outnumbered, especially in the case of having no buddy to cover your back. You can hear them go off and the rift trap even has an area stun against invasion mobs.

To use one, right-click somewhere on the ground to place it down. After a few seconds it will arm and can be triggered by things walking over it. After the payload is spent, the trap sits there empty. You can pick empty traps up as if they were items (they don’t dissapear or lag as they are not items). If you want to remove an untriggered trap, you can use a material probe to safely recover it, otherwise it will drop as an empty trap item if the block underneath is removed.

Flame Trap (folded)

Note that when crafting with buckets, you get the bucket back.
The flame trap, predictably, bursts into a 3×3 fireball when triggered. The fire stays around for a little while like a fire shield, but it tends to block players too.

Rift Trap (folded)

Rift traps are created by charging empty traps in a nexus. At the moment this is the only block that charges them, but other devices could be added (or different traps). These traps usually kill the mob that stands on it, but also does some damage to mobs in an area around it and stuns them for a few seconds. The stun only works on invasion mobs at the moment for technical reasons.
Don’t worry too much about the charging interfering with flux generation. They both go on at the same time, the current item in the output slot just blocks the other item, like in a furnace.

Strange Bone

Feeding this bone to a wolf you own will bind it to an active nexus if it is nearby (several blocks). Your wolf will then respawn at that nexus if it dies. A purple collar indicates the wolf it bound. It also gains some mob attacking behaviour when not sitting.

Nexus Items

Catalysts
These items are essentially the fuel for the nexus. It is a one-time cost to activate the nexus, putting it in its generating state. Then, other conditions take over.
? Nexus Catalyst: Activates invasion mode, generating more flux and causing lots of mobs to attack until you are overwhelmed
? Stable Catalyst: Activates continuous mode. Mobs often engage in night attacks. Difficulty and flux generation increases over time if you keep successfully defending.

Recipes create a mixture. Baking the mixture in a furnace produces the final catalyst.
Catalyst Mixture and Nexus Catalyst

Stable Mixture and Stable Catalyst

Damping Agents
These items currently help control the nexus in continuous mode
Damping Agent

This item prevents the nexus from increasing its power in continuous mode while it is in the slot. It is retrievable.

Strong Damping Agent

The stronger variant actually causes the nexus charge to dissipate quickly in continuous mode. It is, again, removable. If power reaches zero the nexus will deactivate safely.

These are the mobs that will try to kill you. The bulk of the attack forces right now are mostly traditional minecraft mobs, except with all-new behaviour and a purpose behind it. As mentioned, armor is still recommended. I’m working on more mobs and you can expect to see them in a future update.

Zombies
Tier 1

Almost a regular zombie, can claw through blocks and sometimes carries items

Tier 2

Much more durable than regular zombies and can carry better items. A (broken)sword, for example, gives a large attack boost but they lose the ability to destroy blocks.
Tar zombies are from swamps and are highly flammable (protip:kill it with fire!)

Spider
Tier 1

Scales walls with ease and is very fast
Tier 2

In addition to being fast, has amazing jumping ability and can pounce over distances
Tier 3

Do not get too close, he will grab you and throw you away.

Skeleton

Tries to support from range with its bow

Thrower

Beefy, boulder-throwing siege mob. Very dangerous when left alone.
Also has a destructive slam on an 8 second cooldown that can really hurt walls

Pig Engineer

Attemps to defeat terrain obstacles and prefers not to attack a player
Places blocks to try and get over moats of fire, lava or just any hazardous obstacle he can manage
Places ladders to create paths upwards and is the only mob that can tunnel directly upwards
Each pig engineer has building materials but can run out

Zombie Pigman

? Like in the nether, zombie pigmen are resistant to fire
? Can also destroy blocks after making its way through a fire hazard

Creeper
-Functions almost as normal creeper for now, will ad more features in the future.

Blocks have a certain strength against invasion mobs when it comes to digging through them. These can be different from the hardness of the material when a player tries to mine it, but it does determine how long it takes for a mob to dig through. Some blocks also get certain bonuses. Here are some of the block strengths, and the material probe item can tell you these values in-game.
