How To Make object shoot

[hamid14]

What is it you are trying to achieve?
Trying to make a circle shoot a bullet, which is another smaller circle


What is the problem you are having?
Can't figure out how to draw a circle that keeps moving and appears from the x of the shooter


Describe what you have tried to solve this problem
I've tried procedures, using more than 1 loop, drawing a oval at the x and using + 1 in a loop


Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)

Turing:

View.Set ("offscreenonly") var chars : array char of boolean var x,y : int := 100 loop View.Update cls drawfillbox (0,0,maxx,maxy,9) Input.KeyDown (chars) if chars (KEY_RIGHT_ARROW) then x := x + 1 end if if chars (KEY_LEFT_ARROW) then x := x - 1 end if drawfilloval (x,y,10,10,red) end loop

Please specify what version of Turing you are using
4.1

You need to make a procedure that draws the smaller circle (bullet)

then, in your main loop, when the person presses the fire or shoot button or w/e, you put the x value that the bullet starts from into the procedure, and then as the main loop continues, continue drawing the x values of the bullet.

so..

Turing:

procedure Small_Bullet ( x : int) drawfillcircle (blah blah blah) end Small_Bullet %main loop drawfillPerson if shoot then Small_Bullet (value of x) x +=1 end if View.Update end loop

You gotta think of programming this keeping in mind that you have to change the position of the person (even if there is no change) and the bullet, and then update everything simultaneously.

that doesnt work. It says 'x' has not been declared?

Then declare x....

What i wrote was more on the line of pseudocode. The various things that would make it work would require you to have full knowledge of how the procedures/system works. Sorry for any confusion.
