[2005] Acummulator going down, unkown reason.

[Mike S.]

hey guys,
I'm having this weird problem, its a ugly block of code but it works for what I need it to do, minus this one tiny problem... I'm making a sort of space invaders game and when one of the enemies hits the building I need the HP accumulator go down, but it seems to be going down if I click one of the other enemies, if I click the first it stays at five, but if I click any enemy after that no matter where they are the accumulator goes down... I think my problem is here, any help? (sorry its so bad, I'm a beginner)

    Private Sub TimerEnemy1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles TimerEnemy1.Tick
        Me.Enemy1.Top += 3
        If Me.Enemy1.Top > Me.btnBuilding.Top And Me.Enemy1.Left > Me.btnBuilding.Left And Me.Enemy1.Right < Me.btnBuilding.Right Then
            Me.Enemy1.Visible = False
            Me.TimerEnemy1.Stop()
            Me.intaccumulatorHP = intaccumulatorHP - 1
            Me.lblUserHP.Text = intaccumulatorHP
        End If
    End Sub

I don't see anything in that particular code that looks like it would cause the results you are reporting. It appears that the only part of that code that alters the accumulator runs only if the enemy is in a certain place relative to the building. That doesn't seem likely to produce the behavior you are seeing, but you can confirm that pretty easily by putting a breakpoint on the code that decreases the accumulator.

If you reach the breakpoint, check the various pieces of the conditional statement by using Shift+F9 to see whether they are all what you expect them to be.

However, I expect that when you do this, you will see the accumulator decreasing without reaching the breakpoint, which will tell you that the problem exists elsewhere.
