problems with mouse(x-y-z) values

Franz Achatz

Hello,

i have some problems with the xyz-mouse-values.
In the first example only mousez shows the correct value.

gr.textmode(2, 1, 6, %1000)
gr.text(-71,72, Num.Dec(mousex))··
gr.text(-71,56, Num.Dec(mousey))
gr.text(-71,40, Num.Dec(mousez))

In this example mousey is ok.

gr.textmode(2, 1, 6, %1000)
gr.text(-71,72, Num.Dec(mousex))··
gr.text(-71,40, Num.Dec(mousez))
gr.text(-71,56, Num.Dec(mousey))

In this example all values are correct.

gr.textmode(2, 1, 6, %1000)
gr.text(-71,72, Num.Dec(mousex))··
gr.textmode(2, 1, 6, %1000)
gr.text(-71,56, Num.Dec(mousey))
gr.textmode(2, 1, 6, %1000)
gr.text(-71,40, Num.Dec(mousez))

Why do i have to use gr.textmode for the mouse-values all the time???

thank's and best regards
Franz

Just a guess but in the code for text it says:

'' address of zero-terminated string (it may be necessary to call .finish
'' immediately afterwards to prevent subsequent code from clobbering the
'' string as it is being drawn

It looks like the subsequent calls to textmode just make sure it gets chance to be written.

Hi Graham,

many thanks, you helped me out by this one.
When i use gr.finish it works and it saves me 4 longs.

gr.text(-71,72, Num.Dec(mousex))
gr.finish
gr.text(-71,56, Num.Dec(mousey))
gr.finish
gr.text(-71,40, Num.Dec(mousez))

thanks
Franz
