I have given the agent a sequence of move action, but it never appear on the map

Sorry, I didn’t pay attention to this part.
So, maybe I can’t help with your debug process.

It seems that the probelem comes from flatland.

After I update the version of flatland from 3.0.2 to 3.0.5, this strange phenomenon didn’t happen during many times of testing.

Anyway, thank you.

I am not sure whether you can receive the notice of reply.
So I want to @you here Mr. @nimishsantosh

Thanks for you answering.

But I have checked the states of agents and found that when I give it move action its state is READY_TO_DEPART.

Here is picture showing an example of the problem I meet.

QQ图片202111181010031920×1030 123 KB

I print the triple of [position, state, action] of every agent at every step.
From the purple frame, we know that the initial_position of agent[4] is [21,8].
The red frame is the triples of agent[4].
The blue frame shows the first time I give it a MOVE_FORWARD(2) action and at this step its state is READY_TO_DEPART(1).
And the yellow frame shows that there is no other agent conflict with agent[4] since its initial_position is [21,8].

It is so strange that after I give it a move action, it didn’t depart but remained the state of READY_TO_DEPART(1).
After the blue frame, you can see that I give it more subsequent move actions, but it still didn’t depart but remained the state of READY_TO_DEPART(1).

This strange phenomenon does not happen every time, and I really can’t find the reason…

I think even the actions are wrong, at least, it should appear on the map…
I don’t know why…

By the way, I set all speeds 1.0 and didn’t induct malfunction.

Some questions ahout the agents' speed

About the first question of this topic, @dipam has answered.

For the second question, my teammate emailed the administer and received the answer as follow:

"So rather than varying speeds it’s clearer to say multiple speeds.
There are different trains with different speeds. Their speeds are fixed throughout and never vary. Some trains are slower some are faster. Unlike round 1 where all were of the same speed.

Let me know if this clarifies your question."

Hope it is helpful to you as well.

Some questions ahout the agents' speed

Thanks for your help.

Actually, I still feel puzzled about the “varying speeds” at round2. Does it mean that the agents’ speeds are changeable every step during their traveling and we must check the agents’ speeds by function ’step’ every step?

The first part of this page makes me confused.

Could you please explain the “varying speeds” at round2 in detail? Thanks a lot.

Some questions ahout the agents' speed

I want to consult some questions about the speed of agent.

Firstly, I’m not sure about if I understand the speed correctly when it is smaller than 1. Assume that the speed of agent[X] is 0.7, and ‘position_fraction’ is 0. After 2 steps of moving, does agent[X] reach the next cell and the ‘position_fraction’ becomes 0.4?

Secondly, at round 2, the speed is varying. Does it mean that the environment can change the speed and we must check the agents’ speed by function ’step’ every step?

Is somewhere I can know more details about the speed? Thanks.
