Random Zombie Speeds?

[Deko]

Is there a mod or a way to tweak to make zombies move on random speeds if the player has been seen. So there could be all kind walking and running and sprinting in spawn list?

[ErrorNull]

check out the file entityclass.xml and the code within each zombie usually has a parameter that randomizes the speed. i forgot the actual name and not at my computer atm... but this speed randomizer value is presented as a range like -0.08 to 0.2, and added to the zombie's base speed. this randomized value is a narrow range, so you don't see drastic variations in zombie speed.

 

so I'd figure you can do a bigger range like -0.5 to 0.5 and you'll see a larger variation of speeds.

 

btw, the typical zombie speeds are like 0.2 which is close to walking and 0.8 is a brisk jog. feral sprinting zombies are at speeds around 1.3.

From the zombieTemplateMale

 

    <property name="MoveSpeed" value="0.08"/> <!-- Just shambling around -->
    <property name="MoveSpeedAggro" value="0.2, 1.25"/> <!-- Chasing a target min/max (like day or night)-->
    <property name="MoveSpeedRand" value="-.2, .25"/> <!-- Rand added to min aggro speed -->
    <property name="MoveSpeedPanic" value="0.55"/>

 

It looks like the randomizer just affects Aggro speed (based on the comments)

 

From zombieFatCop

 

    <property name="MoveSpeedAggro" value="0.2, 1.2"/>

 

So it doesn't look like they are modifying the base speed, just the aggro speed (there might be examples but I looked at 5-6 of them and they only modified aggro speed).

the comments are a bit confusing. "MoveSpeed" is the speed of the zombie when it doesn't see you. for "MoveSpeedAggro", the first value is the speed of the zombies when they notice and chasing you, and the 2nd number is the speed when they're feral or it turns night time. i regularly change that first number quite often for my various enZombies to customize the speed at which the zombies chase you.

 

i think that the MoveSpeedRand is the random value between -0.2 and 0.25 (or whichever you change it to) that is added to that first number of MoveSpeedAggro. so this was the the number i was thinking about that can be changed to something like say -0.2 and 0.75 to give a larger random speed effect for when zombies chase you.

Good to know.  I just started modding recently so I have learned a lot, but there is a lot that I still have to figure out.

 

So you could also randomize it even more if you add MoveSpeedAggro to each entity with different ranges (if you are inclined) - so one group of zombies are more varied at a lower level while others are varied at a higher level.

 

What is MoveSpeedPanic for (if you know)?  I don't think the zombies panic  🙂

[ErrorNull]

so how it works is that zombieTemplateMale is the entity that all other zombies inherit their default attributes value from. for example, among the many other properties, zombieTemplateMale defines the following:

 

<!-- when zombie does not see you -->
<property name="MoveSpeed" value="0.08"/> 

<!-- 1st number: when zombie sees you, 2nd number: when zombie is feral or is night time -->
<property name="MoveSpeedAggro" value="0.2, 1.25"/> 

<!-- a random number between -0.2 and 0.25 is added to the "1st number" of MoveSpeedAggro" above -->
<property name="MoveSpeedRand" value="-.2, .25"/> 

<!-- speed when zombie is @%$#ed off after you hit it a coule times -->
<property name="MoveSpeedPanic" value="0.55"/> 

 

so any zombie that does not explicitly define their own value for MoveSpeed, MoveSpeedAggro, MoveSpeedRand, and MovespeedPanic, will just take on the above default values.

 

you're right, you can vary the speeds of different zombies by specifying different values for MoveSpeedAggro. for example:

 

custom zombie 1:

<property name="MoveSpeedAggro" value="0.2, 1.25"/>

 

custom zombie 2:

<property name="MoveSpeedAggro" value="0.4, 1.25"/>

 

custom zombie 3:

<property name="MoveSpeedAggro" value="0.6, 1.25"/>

 

this will give each of the above zombies different 'chasing' speeds (0.2, 0.4, 0.6), but have the same speed (1.25) if they're feral or when it's at night. you can also vary the 'chasing' speeds by using only the MoveSpeedRand property. i haven't actually tested the below yet, but this should produce zombies that have the same base speeds (MoveSpeedAggro) initially, but then have a 'randomizer' value (MoveSpeedRand) added to it on the fly to achieve the random speed variation:

 

custom zombie 1:

<property name="MoveSpeedAggro" value="0.2, 1.25"/>

<property name="MoveSpeedRand" value="-0.2, 0.0"/>

 

custom zombie 2:

<property name="MoveSpeedAggro" value="0.2, 1.25"/>

<property name="MoveSpeedRand" value="0.1, 0.3"/>

 

custom zombie 3:

<property name="MoveSpeedAggro" value="0.2, 1.25"/>

<property name="MoveSpeedRand" value="0.3, 0.6"/>

 

custom zombie 4:

<property name="MoveSpeedAggro" value="0.2, 1.25"/>

<property name="MoveSpeedRand" value="-0.3, 0.7"/>

You can also try using a passive effect for the randomisation.

No idea if that is used for zombie entities, though, but it's easy to check.

 

[ErrorNull]

that's interesting. what's the code look like for randomize passive effects? or is there an example item or zombie i can refer to in the vanilla xml?

The stun buff should do it
