| im following NeHe tutorial along these days... it run smoothly until lesson 8... when it come to lesson 9, the C code using structure like this: typedef struct { int r, g, b; GLfloat dist; GLfloat angle; } stars; stars star[num]; in blitzmax, i do this: type stars field r,g,b field dist# field angle# endtype local star:stars[num] = new stars i can't compile it... arghh... im suck at types man how to create new array types then?? i dont even know am i asking the rite question.. |
| ||
| local star:stars[] = new stars[num] |
| ||
| o really... is that simple... *sigh*... im really2 suck then... thanks a lot man... |

| How do you access this array? local star:stars[] = new stars[num] e.g: star[3].r = 10 gives an error... How I can make an array like this but with more dimensions?! |
| ||
| new stars[num] does only initialize the array. it does not create any object. You have to create the objects first through for local i:int = 0 to num-1 star[i] = new stars next For questions on array: the help explains how multi dimensional arrays work with a nice example :) EDIT: fixed an error in my text. |

| Thanks for your help! If anybody else need an answer to this question: How to use a two dimension array with a type as element: Strict Const num:Byte = 10 Type stars Field r,g,b EndType Global star:stars[,] star = New stars[num,num] For Local i:Byte = 0 to num-1 For Local j:Byte = 0 to num-1 star[i,j] = New stars Next Next star[5,2].r = 100 Print star[5,2].r |
