But some conceptual crap that I forget (and every child forgot) They had to go back to the rote learning of the tables and the rules of arithmetic. I would prefer to just know the rules and get a job done. But of course that is just my opinion. And for a practical use of math that makes sense. Unde...

The language of maths is not necessarily the same as the language of speech. You just have to follow the rules of maths because that is all maths is - rules. Sorry I would have to disagree with that from what I have read. Some people can go far with a good memory but they may lack understanding and...

@dodicat, My attempts just result in the coffin spinning out of control! Can you get it on target? So I cheated!! changed line 258 to make finer adjustments to the direction, Dim As pt x2=Getline(mx,my,wheel/90,length) And inserted these guidelines in the display code, circle (200,400),5,rgb(255,0,0...

Now maybe make it into some kind of game? That is the plan, that is also why this 'physics question' is in the 'Game Dev' section :-) I must say I find controlling the ship frustratingly impossible! Of course fun retro computer games usually don't use real physics. These 2d games can always be give...

Your image doesn't show up for me. I had to hold the right button down over the icon to get the image url and paste that into google in order to view the image. I use, https://postimages.org/ I will have to order some of those SN74HC595N IC's to give it a go. Are you going to post your code? Maybe s...

@badidea, I like it! Now maybe make it into some kind of game? Perhaps manoeuvring through an asteroid belt looking for natural resources or combat with opponents? With asteroids to give a sense of relative motion I would suggest if you can make the origin always be on the space ship? Maybe manoeuvr...

1) Put the variables

This replicates basiccoder2's code behaviour.

Well worked out dodicat :)

@ITomi, I did try to figure out where the code wasn't working as you expected but I am not very good at unravelling other people's code instead I find it easier to just write my own version based on the behaviors required. I have added code to the previous post to change the color of the scroll butt...

@dodicat, Missed that I was just too pleased to see it "working" to notice :) ITomi wants it to scroll only if the player releases the button above an arrow icon which is not how I see buttons usually behaving which is to act if the mouse button is pressed while over a GUI button. So I won...

It is quite hard for me to follow. But if you omit leftmousebuttonpressed=0 from the first bit it seems to be OK. It also seems to work if you make it two if/then blocks instead of using the elseif I also couldn't see the reason for using ubyte and ushort and changed them to integer but that had no...

How can I read the string on the Arduino side, bit by bit? A string is a list of characters. Read each character one at a time in a for loop. Are you using any online tutorial example? Test your Arduino code using the Serial Monitor. Type in your 18 long string in the edit box then click the Send b...

My problem is now with the FOR loop, because I don't understand why is it not execute the SELECT CASE in case of i=0 ? (See the code in my first post.) What happening with the SELECT CASE within the loop? Maybe it has something to do with other unseen parts of the code. Your code is too complicated...

Would you be interested in sharing any of that? Does the PC use FreeBASIC code?

Sadly I wasn't kidding. When you advised else where that I needed root rights and gave the example. su root That didn't work either until I realised you meant to use your name in place of the word root. su pi I do need to learn a bit more about Linux and its console commands. Anyway your effort and ...

It seems to be doing what mine did? Returns the previous input rather than the current input?
