How everybody! In this entry we will see how to write in the screen, to know for exemple how to show things like information or our score. Take a look at this code: We have already seen drwa string but l et me explain the new keyword used: locate  to drive the cursor used by print to the desired position in the screen. print to print a value in the screen. When we execute this code we can see this: locate and print works together and understand the screen like tiles of 8x8 pixels where there's only place for a character (1,2,3,...,a,b,c,d,e,...,!"·$%&/..., etc) in each tile, starting at 1,1 position whre the fist number is the value of the row and the second value the column that's why the second message appears at the second row and starts at the fist column. The colors used are the default (black/white) or the one's selected by the color instruction that we talk about in the past entry. This is e nough by now, i...

G'day everybody! In this entry we will see the collisions, and we will use a concret one wich is the perfect superposition between two elements, as it used for pac-man and the ghosts. We have a perfect superposition when te coordinates of two elements are the same, same value for x axis and same value for y axis. Take a look at the new code of the day: Let me explain the new keywords used: dim as string  to declare a new variable that will contain an string, an string is delimited with an initial " and a final ". draw string  to draw a string on the screen at the point indicated. The sintaxis is draw string (x,y),string in our case draw string (0,h/2),message When we execute this code we can move the white square toward the other ones and the message in the screen will remember the color with which square the last collision occurs. Today's code and concepts are very important because we have an square with controlled interacti...
