say Expecting 'Next' =\

[amcadam26]

did you put "next" after the "rect" line?

[skaruts]

What I don't get is, the rand() command doesn't really randomize it.

Every time I run it it gives me the same squares at the same location and the same color.

Any clues?

[amcadam26]

add this to the start of the program:

SeedRnd(MilliSecs())

you should now get proper randomness.

lol i did exactly what you did and when i tried to run it, it said not enough paramaters =/

this is what i wrote

Graphics 640, 480, 16, 2

For x = 1 To 20 Color Rand(255), Rand(255) Rect Rand(500), Rand(400), 50,50

Next

WaitKey

End

[amcadam26]

it should say

color Rand(255),Rand(255),Rand(255)

Its hard to understand guys but the easyest way i find to learn this is buy watching it then follow this tutorial step by step, listen carefully, keep watching this video fpr about 8 times in a row paying real close attention then move on thumbs up if u agree!

@skaruts you need a seed, random is not realy random, it just does some math to chamnge a number

[DKmiyamotoDK]

i don't really get this

[pufixas]

haha continioung!!! no... wait...

[TheMessi10ever]

CONTINUING !

My first language is not English though :P

[CillersFan]

For x 1 to 20 means the loop will run 20 times, in this case it will create 20 rectangles.

[benitofinito]

For x = 1 To 20???? what's that mean?

[igooog]

@skaruts Yerp, always does that

[Bankser888]

I keep getting expecting end of file.
