Hangman is a classic word game in which you need to need to guess as many possible letters in word, so you can guess the word, before running out of tries (lives).

Upon running out of tries, you are hanged!

The game can be played in R Studio, where the user inputs new letters in console, and the picture is being drawn (using library ggplot2). The picture consists of 7 false tries, so  it is drawn in 7 steps.

The diagram is created using simple X, Y coordinates with groups for determining the steps:

level1 <- data.frame(x=c(1,2,3,4,5,6,7,8), y=c(1,1,1,1,1,1,1,1), group=c(1,1,1,1,1,1,1,1))
level2 <- data.frame(x=c(4,4,4,4,4), y=c(1,2,3,4,5),group=c(2,2,2,2,2))
level3 <- data.frame(x=c(4,5,6), y=c(5,5,5), group=c(3,3,3))
level4 <- data.frame(x=c(6,6), y=c(5,4), group=c(4,4))
level5 <- drawHead(c(6,3.5),1,10,5)
level6 <- data.frame(x=c(6,6,5.8,6.2),y=c(3,1.5,1.5,1.5), group=c(6,6,6,6))
level7 <- data.frame(x=c(5.5,6,6.5),y=c(2,2.5,2), group=c(7,7,7))
levels <- rbind(level1,level2,level3,level4,level5,level6,level7)

Drawing itself is created by using a simple function using ggplot2 library:

drawMan <- function(st_napak) {
ggplot(levels[which(levels$group<=st_napak),], aes(x=x, y=y, group=group)) + 
geom_path(size=2.5) + 
theme_void()
}

The function draws the hanging man in 7 steps

All the rest of the logic is fairly simple, continue until you find the correct word, or until you are hanged. Section of the code:

beseda <- readline(prompt="Word: ")
iskana_beseda <- replicate(nchar(beseda),'_')

while (active == TRUE) {

if (i == 0) {
writeLines(paste(iskana_beseda, collapse = " "))
}
crka <- readline(prompt="Enter Letter: ")
izbor <- rbind(izbor, crka)

#iskana_beseda
if (grepl(crka, beseda) == TRUE) {

cilj <- rbind(cilj, crka)
iskana_beseda <- zamenjaj2(beseda, crka)
#print(zamenjaj2(beseda, crka)) 
print(paste("Yay!","Try N:",i+1,"Wrong letters: {",(toString(paste0(cilj_n, sep=","))),"}")) 

if (as.character(paste(iskana_beseda, collapse = "")) == beseda) {
active == FALSE
Print("Bravo, win!")
break
}
{code continues.....}

… and the rest of there code is  here — >> github.

When playing, this is how it looks from my R Studio.

As always, complete code is available at Github.

Happy R-hanging
