In this tutorial we’ll add random battles to our game.

For now, we’ll only add them to the World scene (Assets/Scenes/) outside of town, so open it.

We’ll do two things:

• set the battle scene variable
• add random battle areas

Let’s get to it.

Battle Scene Variable #

Create a new empty game object using the scene hierarchy’s context menu: Create Empty

Change the newly created game object’s name to Set Battle Scene.

Variable Changer #

Add a Variable Changer component to the game object using the component menu.

Variable changers are used to change, well, variables – without having to go through a schematic. They can e.g. be started automatically when loading the scene (which we’ll do), when entering a trigger or started by interacting with them.

Variable Change Settings #

We’ll set the battleScene string variable to the scene name we want our battles to take place in.

Start Settings #

These settings define how the variable change is started – we’ll use the Auto setting’s Start start type (i.e. the machine will start when the level was loaded or the game object was instantiated).

Components like the Variable Changer have quick-setup buttons available, the Autostart button will handle the setup for us.

That’s it for the variable changer – now, each time we enter this scene, the battle scene used by the battle start schematic will automatically be set to the Forest Battle Arena scene.

Adding Random Battles #

Next, we’ll set up the Random Battle Area. This component will start battles while the player moves within it’s trigger.

We can use the scene hierarchy’s context menu to create a ready-to-use setup for us: ORK Framework > Battle > Random Battle Area (3D)

This’ll create a new game object with a Random Battle Area component and a Box Collider 3D used as trigger.

Let’s adjust it to our needs.

Transform #

We’ll position it to cover the area outside the town gate.

Random Battle Area #

Now, let’s set up how often a random battle happens and which enemies can appear.

Random Battle Settings #

The Random Chance Settings in combination with the distance settings determine how often a battle happens. We’ll keep the default settings for battle chance and check interval.

Combatant Settings #

We’ll add multiple combatants/groups that will be used for random battles. Which one is used is determined by a chance check – each combatant/group we add defines the chance it has to occur.

The total of all chances should be 100 to have a full range of possible enemies. However, you can also define less or more – less would mean that if no enemy was found, no battle occurs. More, well, all exceeding the maximum chance (100 for all chance checks, can be changed in Game > Game Settings) would never occur. You can see the total chance of all added combatants/groups at the top of the component’s settings.

Let’s get to it. We’ll begin with editing the already added Combatant 0.

That sums up to 100 percent – 60% chance to fight a wasp, 40% chance to fight a snake.

Box Collider #

We’ll adjust the size of the box collider to cover the whole area outside the town gate.

More Random Battle #

Copy the Random Battle Area game object we just created, we’ll adjust it and use it for the upper part of the scene.

Transform #

We’ll position it to cover the upper area of the scene.

Random Battle Area > Combatant Settings #

We’ll change the chances of combatants to appear and also add the combatant group we’ve set up.

Combatant 0 #

Combatant 1 #

Combatant 2 #

That sums up to 100 percent – 30% chance to fight a wasp, 30% chance to fight a snake and 40% chance to fight a group of 2.

Box Collider #

We’ll adjust the size of the box collider to cover the whole area outside the town gate.

That’s it for the random battle setup.

Save the changes you’ve made in the scene.

Testing #

It’s finally time to fight! Hit play in the World scene and run outside town.

Everything seems to be working, we zoom into the battle and can attack the enemy (and get attacked or poisoned back).

Since our player doesn’t have any abilities (beside the base attack), the Ability battle menu option currently has nothing to display – also, there are no items in the player’s inventory, so the Item battle menu option is grayed out.

However, the actions appear to be happening at the same time. This is due to them not yet being animated, so they’re over in an instant.

Also, the camera is a bit far away, let’s change that.

Adjusting the Camera #

Open the Makinom editor and navigate to Base/Control > Game Controls.

ORK Control Settings > Camera Controls > Zoom Settings #

We’ll use zooming of our Top Down Border camera to define different distance and height limits for field and battle camera.

We don’t actually use any input to zoom, i.e. the player can’t zoom in or out, but we’ll set a limit for the camera.

Height Settings #

Distance Settings #

Save Changes #

And that’s it!

Save the changes using the Save Settings button at the bottom of the editor.

Testing Again #

Hit play and start another battle outside of town.

That’s much better!

Next, we’ll start animating our actions.
