How to move things I draw in Turing?

[jzc1995]

What is it you are trying to achieve?
I'm new to here and I'm new to Turing. And I am not very good at English.
I want to move a star form where it is to another place that I want.
What is the problem you are having?
For example, I have a star at (50,50,100,100), and I want to move it to (100,100,150,150), what can I do?
And can I control the its moving speed?
Thanks for help me!
Describe what you have tried to solve this problem
I try to find the language I need in the Turing Reference, but I can't understand it.
I also try to draw star, remove star, draw star, remove star..... but that is to complex, and I post what I try below.
Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)

setscreen("graphics:800;600")
drawfillstar(50,50,100,100,yellow)
delay (100)
drawfillstar(50,50,100,100,0)
drawfillstar(55,55,105,105,yellow)
delay(100)
drawfillstar(55,55,105,105,0)
drawfillstar(60,60,110,110,yellow)
delay(100)
drawfillstar(60,60,110,110,0)
drawfillstar(65,65,115,115,yellow)
delay(100)
drawfillstar(65,65,115,115,0)
drawfillstar(70,70,120,120,yellow)
delay(100)
drawfillstar(70,70,120,120,0)
drawfillstar(75,75,125,125,yellow)
delay(100)
drawfillstar(75,75,125,125,0)
drawfillstar(80,80,130,130,yellow)
delay(100)
drawfillstar(80,80,130,130,0)
drawfillstar(85,85,135,135,yellow)
delay(100)
drawfillstar(85,85,135,135,0)
drawfillstar(90,90,140,140,yellow)

Turing:

Please specify what version of Turing you are using
The version of Turing that I am using is 4.1.1.

i'd suggest storing the position of the star in variables, and then changing those. What you have of colouring white over the old star, and drawing a new one after you change the position.

You should use a loop for this so that you only need about 5 lines of code. (a for loop would be best I think)

If you do not know anything about loops, I'd suggest reading the Turing Walkthrough tutorial (I believe it's a sticky on here)

Thanks, I should think of that, I know loop and variables,Thank you for your help!

Eh well this will shorten what you wanted to do a lot.

var pos_x1, pos_x2 : int
var pos_y1, pos_y2 : int

pos_x1 := 50
pos_x2 := 100
pos_y1 := 50
pos_y2 := 100

for i : 1 .. 10
cls
drawfillstar(pos_x1,pos_y1,pos_x2,pos_y2,red)
pos_x1 := pos_x1 + 10
pos_x2 := pos_x2 + 10
pos_y1 := pos_y1 + 10
pos_y2 := pos_y2 + 10
delay (25)
end for

You can use a for statement with what your trying to do.

It will run though the for statement 10 times before stopping.

Theres a lot of other ways to do this but i find this is the more effective.

So I hope this will help you.
