Help with Mouse.Where

[D_homes]

Hey guys, I only have about two months experience with Turing (I'm in grade 10 taking ISC) so go easy on me.
I am trying to make a game where enemies are moving from the left side of the screen, the goal is to eliminate them before they reach the right side. The user clicks on the enemy to kill it. I understand how to program the rest of the game but I'm running into some serious problems with Mouse.Where. A simple delay and cls could solve this problem but it doesn't work with the off screen buffer which i used to eliminate the flashing.

Don't tell me to go and read the mousewhere tutorials ... I've already read them and they didn't help me at all with the goal i was trying to obtain with my game.

How could i make it so that after a certain amount of time, the picture is removed. This is because if you click somewhere, the bullet appears there, but if you don't click somewhere else, the picture remains there.

Turing:

View.Set ("graphics, offscreenonly") var x, y, b : int var bullet : int ammo := 120 x := maxx div 2 y := maxy div 2 b := 0 var bulletx, bullety : int := 200 bullet := Pic.FileNew ("bullet_171.gif") loop     Mouse.Where (x, y, b)     if b = 1 and y > bullety then         bullety := bullety + 2     end if     if b = 1 and y < bullety then         bullety := bullety - 2     end if     if b = 1 and x > bulletx then         bulletx := bulletx + 2     end if     if b = 1 and x < bulletx then         bulletx := bulletx - 2     end if     Pic.Draw (bullet, bulletx, bullety, b)     View.Update     cls end loop

Also, how would i implement an ammo system, i tried it, and failed. I tried it as part of the loop, but the number decreases way to fast and if i put in a delay, the bullet moves way to slow.For some messed up reason, it also messed up the Mouse.Where by making the user having to click multiple times to move the bullet where he/she wants it. Would it be best to use the ammo as a procedure on its own?

Based on the code you posted, the bullet moves towards where the mouse currently at, and it only moves when the mouse it is clicked. Is this an intended behavior?

If it is than you could use a boolean variable to determine if the bullet should be drawn or not. Initially the boolean variable would be set to false, and when the mouse is clicked you would set this variable to true. If the bullet hit an enemy than you would set the boolean variable to false.

Turing:

... var drawbullet : boolean := false %If this variable is set to true than the bullet will be drawn, otherwise it won't loop     Mouse.Where (x, y, b)     if b = 1 and y > bullety then         bullety := bullety + 2         %Set drawbullet to true     end if     ...     if drawbullet then %If the bullet should be drawn         Pic.Draw (bullet, bulletx, bullety, b)     end if     if bullet_hit_enemy then         %Set drawbullet to false     end if     ... end loop

However, what I think you really want to do is have the bullet travel to where the mouse was clicked even when the mouse is not clicked. Is this what you want instead?

[D_homes]

I want the bullet to travel where the mouse is clicked, but i want the bullet to disappear after a certain amount of time if the user does not click again

never mind, i figured it out. Thanks for your help!

Quick question...
How did you post the Turing code like that?

use the tags

code:

[code] at the beginning of the code.

And [/code] at the end of it.

Whenever i try that it doesn't work so i just use [code].

Just because you can't get it to work for yourself, while it clearly works for others, perhaps you shouldn't be telling new members to not use an available feature.

Also, try to use it now, in a reply. I want to see in which way it doesn't work.

Alright thanks...
