Mad Pod Racing - Puzzle Discussion

#973

Unfortunately the simplified inputs provided before gold league make it very difficult to do what you are trying to do. The angle shown in the viewer is the angle the pod is facing and that information isn’t provided in bronze, so I think the only way to know it is by keeping track of it manually. I’d strongly recommend trying to get to gold league before trying to implement accurate physics modelling, it’s much simpler.

You control the direction (x and y coordinates) and the thrust (an integer between 0 and 100) of your pod To do that, you have to update the code which prints/outputs to the console, I just started (got to Wood League 2), and I’m rather confused about what the target location which I specify in the output actually does; how it’s used to calculate what the pod does The guys and gals that presented the **Gold League version of Mad Pod Racing were nice enough to also show all the numerical constants and details necessary to simulate your very own Mad Pod Racing arena.

@RoboStac, @breaalina02, thank you much for explainations.

I will try my best to promote to at least silver league without the physics modeling, and will report if I have any success with it.

But honesly, I went a little desperate because I stuck in bronze league for more than two years. I was promoted to bronze in 2022 and is still here…

Hi, I’m kinda new, I’m at Bronze and I can’t find out how to use the BOOST function can anyone help me I’m using Lua cuz i’m basically the only one who uses it and cuz idk but thanks in advance

#977

The syntax to use BOOST in Lua is:

print("8000 4500 BOOST")

i.e. replace the thrust value with the word “BOOST”.

#978

OK thanks i’ll try my best to adapt it with my code

#979

This league stuff is very confusing. How do you select a specific level?
Think my bot won multiple levels without changes so I just skipped over the levels

#980

Hello world, I’m stuck on Wood 1.
Any tips to get further ?

#982

Be sure to use the boost if the distance to the next checkpoint is big enough.
Also calculate the thrust for corners. Do not drive at 100 speed at all time ^^

#983

Already, since days.
More ?

#984

Target the nearest point at the edge of the next checkpoint (and don’t change it as long as the distance to the checkpoint keeps decreasing).

#985

Done. Anything else ?

#986

i am confussed why is this code not working
if(next_checkpoint_angle > 90) {
printf(“%d %d 0\n”, NCX, NCY);
}elseif(next_checkpoint_angle < -90) {
printf(“%d %d 0\n”, NCX, NCY);
}elseif{
printf(“%d %d 100\n”, NCX, NCY);
}
}

#987

The last elseif should be else?

#989

thanks i changed it to
if(next_checkpoint_angle > 90 || next_checkpoint_angle < -90) {
printf(“%d %d 0 \n”,NCX, NCY );
}else{
printf(“%d %d 100 \n”, NCX, NCY);
}
and now it works but can you explaint the boost function it doesnt get in my head

#990

From the puzzle statement available in higher leagues:

A boost is in fact an acceleration of 650. The number of boost available is common between pods. If no boost is available, the maximum thrust is used.

Syntax: replace the thrust with the word “BOOST”, e.g. "%d %d BOOST\n".

#991

thanks for the tip

#992

Try reducing speed ahead of time (except for the last checkpoint in the last lap). You’re overshooting the checkpoint by a lot and then still have to reduce the speed and turn around.

#993

It was already into, except for the last checkpoint acceleration.
Thanks

#994

Ok, seems that wood 1 needs still a tiny bit more to complete.

I will only give a hint for the next step:
Keep track of all the checkpoints and the turn angle between them. This will help you in round 2 and 3.
