whats matter with this screen

@sujun you can instead use an input based activator like the ones on the segments and have a variable going from 0 to W being W the number of columns.
.
Then by changing that variable in vizzy you can decide precisely what column to update and you could even have another variable for the row to change specific pixels, this way you would only use 3 variables (column, row and intensity) but you may have problems with the refresh rate.
.
By having H variables (H being the height) with the value of each pixel of the column in each one of those and one variable to control the column then you can simplify this.
.
Another option is to have a scroll screen, where you only update one column and then copy the column on the left to the column on the right (or the other way around).
.
One last option to have only 2 variables and not much drag is to use one variable for the columns and another as a binary list of on off states of every row, you don't have intensity control but you can have a very fast screen.
.
I can make you some examples if you want. You may run into a problem with the update order, be careful enabling and disabling the inputs. An easy solution would be to have an AG turning off all pixels at the same time during the transitions.

i hope you can know what i mean because my English is poor

for example i use letter "L" to instead the light and use "B" to instead the block of each line
then a 5*5screen will be like this
L L L L L
L L L L L
L L L L L
L L L L L
L L L L L
B B B B B
(i group a line together)
the light Will be controled by the input value inside the block
for example when the value of the block is 3 and the third light of this line will turn on and when the value is -3 it Will turn off.
and the block input is the variable from a1 to a5 inside a program .
but when i set the a1 to 5 then all light of this line turn on and some light of another line turn on too.

@@pedro16797 there is a block of each line the light will be controled by the block by checking its input value . and the block's input will be controled by the vizzy variablen

@NathanMikeska I think he is using a Vizzy variable as input controller. My best guess is that he is trying to make a screen sweep update.
@sujun I think there's a better method if that's what you want. If it is tell me and I'll make you one example.

I'm not sure what you are trying to do. What is supposed to be the input to each input controller? It looks like they are trying to use themselves as an input.

good job
