athena's Issues

Get Rid of Seperate Debug Engine

Merge the "normal" game engine and the debug engine. In order for this to work, we have to change the way the batch rendering works currently. As the PhysicsDebugSystem uses a ShapeRenderer under the hood, we have to make sure that our main SpriteBatch's end method has been called before calling update on the debug system. As long as we use

game.batch.use(camera) {
    engine.update(delta)
}

to update the engine, the PhysicsDebugSystem won't be able to work properly inside it.

Add LibGdx Headless Mode to UnitTests

The LibGdx context is needed to test the SpriteSerialization process for example as the process relies on loading texture Assets.
The addition of more libgdx specifc unit tests would seem helpful in general.

This would also help to test the particle system.

Player Can Attack Too Often in SlowMo

When the deltaTime is lowered, the player can still attack independent of the deltaTime.

We need to change the TimeUtils.millis() implementation and instead use a deltaTime dependent variant.

Serializer for gdx.graphics.g2d.ParticleEffect 

package com.theovier.athena.client.ecs.prefabs.serializers

import com.badlogic.gdx.graphics.g2d.ParticleEffect
import kotlinx.serialization.KSerializer
import kotlinx.serialization.Serializer
import kotlinx.serialization.encoding.Decoder

@Serializer(forClass = ParticleEffect::class)
class ParticleEffectSerializer : KSerializer<ParticleEffect> {

    override fun deserialize(decoder: Decoder): ParticleEffect {
        return ParticleEffect()
    }
}

will throw

Something with the public serializer invoking protected fields on the ParticleEffect seems to be off.
