Android Question Type initializing

[wroyw]

Hi,

I have a own class where I define a variable in Class_Globals :

type T1 ( v1 as float , v2 as float )

type T2 (V3 as float , V4 as T1)

but if I want change the V4 value like this :

V4.V1 = 1

I get an error : java.lang.NullPointerException: Attempt to write to field 'float b4a.example.csv3$_V4.V1' on a null object reference

What make I wrong ?

 

[wroyw]

sorry thats right

Class_Globals :

type T1 ( v1 as float , v2 as float )
type T2 (V3 as float , V4 as T1)
public MyVar as T2

and in my code :

MyVar.V4.V1 = 1

(V4 = NULL in degugger)

Did you initialized your customtype?

myvar.initialize

 

[wroyw]

that was my mistake :-(
Is it neccessary only for own types or for all valiables

 

[DonManfred]

Type, list and map

 

[wroyw]

okay. Thank you

 

[wroyw]

hmm, now I have another problem ...

Class_Globals:
Type T1 ( Bool1 as boolean , Bool2 as boolean)
Type T2 (Int1 as Int , Bool as T1)
Type T3 (Float1 as float , Type2(3) as T2)
public MyType as T3

Initialize:

MyType.Initialize

but now is MyType.Type2(0).T1 = Null ...

Please use [code]code here...[/code] tags when posting code.

 

[wroyw]

thanks

Class_Globals:
Type T1 ( Bool1 as boolean , Bool2 as boolean)
Type T2 (Int1 as Int , Bool as T1)
Type T3 (Float1 as float , Type2(3) as T2)
public MyType as T3

Initialize:
MyType.Initialize

Why is is MyType.Type2(0).T1 = Null ?

Type2 is an array with 3 uninitialized T2 objects.

You need to initialize it:

MyType.Type2(0).Initialize
