Program to display computer screen 3 times before at 33% opacity- help!
« on: March 15, 2012, 06:36:03 pm »
Hi,
Could someone make a program for me that displays the screen and 2 times before, all in 33% opacity? It would refresh every *blank*(You can choose) milliseconds. That way I could have stuff for my NXT look grayscale.
Would it really be that hard? Could somebody?

Thanks, and have a nice day,
nxtboy III

I've no clue how to approach this :/ Does the NXT natively support grayscale? If not, how easy is it to do bitwise logic?

No, the NXT does not natively support grayscale, just like the TI 84. What's bitwise logic?
Also I was talking about a computer program to do this, so I could use a utility that captures my NXT's screen (It captures it in monochrome). When I said "screen", I was talking about the computer screen, not the NXT's.

I can program both the nxt and the computer.  No, grayscale shouldn't work on the nxt.  It's not really made for games like that.  What are you programming the nxt with?

Might I suggest, if you want to use it as a controller, to use the usb routines from lejos, and write a computer program that emulates itself as a virtual key-board.  You can configure the buttons on the nxt to respond to certain key-presses.

My main question, though, is why you want to do this.

I already have made grayscale games on the NXT. Check in my sig, After Dark. It's a grayscale NXT game. I wanted a computer program to show the computer screen 3 times (current frame and a certain time before (twice) ) at 33% opacity.

Basically a NXT emulator for Windows? (with Axe/83+ASM grayscale style scanlines?)

That would be better, (It would be AWESOME) but I was just asking for a program to display the computer screen 3 times (current frame, and frame at a certain time before(Then again))at 33% opacity.

To completely capture the whole screen sans-ss and then combine it with other ss, and then redisplay the combined ss fullscreen would take some sort of native hacks I feel like.  This was the closest i could get in java i think, good enough?

Cooliojazz he meant multiple screens as in motion-blur

EDIT Actually nvm, for odd reasons the fuirst time I ran your program it ran so fast that I didn't see the motion blur.

How about it could take just a part of the screen, like you did in your .jar program, then it will save a screenshot every n milliseconds(you type in what n will be), and it will display the current screen, and 2 ones before.
