Adding new actions

[valko073]

Hi guys, first of all I wanted to thank you for this awesome framework!

I am curious if there is a way of adding new actions for the agents, i.e. a second type of attack which has different properties and effects.

Hi,

You have to hack the engine. I can point you to some related code.

1. Here we record the action for agents
   

   MAgent/src/gridworld/GridWorld.cc

   Lines 445 to 451 in 92256aa

   	if (act < type.turn_base) { // move
   	move_buffer_bound.push_back(MoveAction{agent, act - type.move_base});
   	} else if (act < type.attack_base) { // turn
   	turn_buffer_bound.push_back(TurnAction{agent, act - type.move_base});
   	} else { // attack
   	attack_buffer.push_back(AttackAction{agent, act - type.attack_base});
   	}

2. Here we compute the results of attack actions
   

   MAgent/src/gridworld/GridWorld.cc

   Lines 474 to 480 in 92256aa

   	// attack
   	#pragma omp parallel for reduction(merge: render_attack_buffer)
   	for (int i = 0; i < attack_size; i++) {
   	Agent *agent = attack_buffer[i].agent;
   	if (agent->is_dead())
   	continue;

Current actions are numbered by the order of (move, turn, attack). If you want to add another type of attack, you can put them after the current actions, i.e. (move, turn, attack, new attack)
