In C language
How to attack?
everytime I write printf(“Attack”);
It shows error
help

#263

To attack, you need to write the name of the enemy you want to attack. If you use printf("Attack");, it will try to attack an enemy called “Attack”, however there are no enemies with this name :worried:

I’m working with C++, i think i’ve done my code correctly but the cannon doesn’t shoot, could you help me please?

#265

I was having this problem and it turns out there is a print statement at the bottom i was using python and that was holding up the loop once i took it out it started to work. I hope this helps :slight_smile:

#266

I just find some errors, you can not do this.
like:

  1. dist is integer, and closet_enemy is a point. how can you use “dist < closet_enemy”?
  2. how can you use strcat function?

Hi, i try to make a struct to storage data from enemies but in main function cin does not get the name of enemies.
Any help please?

#include <iostream>
#include <string>
#include <list>
#include <algorithm>

using namespace std;


 struct Enemy
 {
     int dist;
     string name;     
 }; 
 
int main()
{
    list<Enemy> enemies;
    
    // game loop
    while (true) {
        
        Enemy a;
        cin >> a.name; cin.ignore();
        
        cin >> a.dist; cin.ignore();
        
        
        enemies.push_back(a);
        
        
        cout << "Enemy: ";
        cout << (*enemies.begin()).name << endl;
        cout << "HotDroid" << endl;
        // To debug: cerr << "Debug messages..." << endl;
    }
}

Hi all,
please look at this snippet:
val enemy1 = readLine // name of enemy 1
val dist1 = readInt // distance to enemy 1
Console.err.println(enemy1+" “+dist1)
val enemy2 = readLine // name of enemy 1
val dist2 = readInt // distance to enemy 1
Console.err.println(enemy2+” "+dist2)

the output is:
Standard Error Stream:
Nobody 9999
Rock 70
WTF the Nobody with distance 9999 is?

#270

“Nobody” is given when there’s only one enemy on the screen. Since the input is hardcoded to have 2 enemies always provided, if there’s only one, then a “dummy” enemy of “Nobody” is given for one of them. Since it is “very” far away, it should not have any adverse effect on the logic of your program.

@player_one thanks for your answer. The strange thing is that event if there are more then 2 enemies visible (sometimes are 5 at once) you cannot get the name and range of the 3rd, 4th etc. Bug or feature?

#272

That’s by design. The description clearly states:

On each start of turn (within the game loop), you obtain information on the two closest enemies

If it seems like the design is a bit strange it’s because this puzzle has evolved. It actually used to give you information about all enemies on screen, but that seemed a bit hard for newbies, so now it always makes you choose between two options.

Hello Everyone,

This is Prasad. I am trying to complete first program in URL

This program is about destroying the enemy ships by shooting the closest enemy on each turn.

I am trying to figure out how to pass inputs to this program.

Would be very helpful if someone can answer.

Thanks!!
