Zombie is the most simple type of enemy.
Its locomotion is basic and its logic is a sort of "seek and destroy" behaviour.
Otherwise if many zombies are placed in the level, with effective hit and death reactions, they can guarantee a decent fun.
In
EasyGamePack installation there are
male and
female zombie
prefabs.
Male zombie
prefabs are located into
EasyGamePack\Characters\Zombi\MaleFemale zombie
prefabs are located into
EasyGamePack\Characters\Zombi\Female
Zombie behaviour is built up with 2
gamemachines, they are located into
EasyGamePack\Characters\Zombi folder:
-
Locomotion: it determines what are the movements (animations) of the zombie basing on its direction and its velocity and how the zombie must react to a hit or the death.
-
zombi3: it is the third iteration of the zombie
logic. It makes the zombie to patrol and/or chase and attack the player when he is nearby.
Following are the parameters of the locomotion gameMachine:

ANIMATIONS
This means that every zombie has a
modelscript containing the list of animations that he can perform in the
gameMachine.
The animation slots in the modelscript are simply references to real source animation files, this means that changing these references you can change the animation set maintaining, at high level, the same animation names. This is why there is more than 1 modelscript containing different set of animations for a zombie.
Changing the
modelscript in the zombie class changes the way in wihich zombie performs some anmations (like chasing for example).
In this version of
EasyGamePack there are the following
modelscripts you can use for the zombies, all of them are located in
EasyGamePack\Characters\zombi\Female folder :
| | They can be used also for male zombies because the source animations are the same (thanks to retargeting)
|
PATROLING
If no player is nearby, a zombie simply patrols a given zone.
A zombie can patrol only one zone. You can set the
ID of the zone to patrol (
patrolID) in the "
logic" GameMachine of the zombie.
| | If a zombie doesn't find any patrol point of specified ID, in order to avoid stucking, it starts to find a patrol point regardless of its ID.

-
Be sure you have checked the
show->helpers option in the
scene viewport toolbar.
-
-
-
Check the
multiple creation button
-
Click in the scene where you want to create the point
ATTACKING
When zombie attacks player he randomly performs 2 alternative actions:
-
Biting: the biting animation is the same for all zombies. When it is performed the player character movements are blocked for a while.
-
Melee attack: When zombie performs this attack he executes an animation from the
modelscript list. Since there are more than 1 attack animation listed in the
modelscript, you can choose what the zombie must execute using the parameter
attack_anim in the gamemachine.
CREATING A NEW ZOMBIE
If you alreay have a "static" character 3d model, the simplest way to integrate a new character for EasyGamePack is to use MIXAMO service.
MIXAMO is an online service that takes in input a static single mesh character and convert it into a skinned, animatable, model.
Once you convert your model into a skinned MIXAMO model, you can import it into your s2engine project by drag and drop the model file in the project browser folder you want to locate the character files.
Take care about some s2 importer settings:
Import Geometry<TODO>: Insert description text here...
|
|
Collapse FBX<TODO>: Insert description text here...
|
|
Once you have successfully imported the model you have to do some changes in order to make it compliant with EasyGamePack system:
-
Inspect the imported model in order to open the
model editor:
-
Create a parent node of the model
Hips node:
-
-
Click on Options combobox and choose "
AddParentNode"
-
Rename the new node as
ROOT and set X Rotation to 180. This should rotate the model by 180 degrees along its vertical
-
Add a parentNode on top of
ROOT node following the same procedure used for
Hips node:
-
Rename the new node as "
rotRoot".
-
Now you must add collision capsules for ragdoll effect.
We can copy them from one of the pre-made zombie models. Select one of the premade zombie models and inspect it.
-
In the model editor viewport select
show->Joints to visualize the collision capsules.
-
-
In the options combobox select "
Copy All"
-
Now Select again your imported model. In the
model editor physics tab choose
Paste All on the combobox dropdown menu
You should see the collision capsules on the new model if all gone right.
After prepared the imported model you have to give it the logic for the game.
The best way to do this it to change the model of a premade zombie:
-
Insert one of the premade zombie into the scene.
-
Drag and drop your imported model into the
model parameter of the premade zombie.
-
Reset the materials if needed.
