Hi everybody!

Once again I'm back to work on the masterpiece "Pin-Go," a pong clone with breakout style action. I'm attempting to add powerups (e.g long paddle) but it's not working quite right.

I have 2 variables, 1 to determine if player1 should get the powerup, and one to determine when the other player gets one. The variables switch back and forth whenever the paddle hits the ball. (So if you hit the ball, you get the powerup) But it's always detecting the computer player as getting the powerup.

Here's the basic bouncing code:

+ Code Snippet

if ballx#>6.5 and ballx#<7 and ABS(player1pos#-ballz#)<1.5
   balla#=360-balla#
   player1hit#=1: player2hit#=0
endif

if bosslvl#=0
   if ballx#<-6.5 and ballx#>-7 and ABS(player2pos#-ballz#)<1.5 then balla#=360-balla#
   player2movespeed#=.5+((.2)*(level#-1))
   player2hit#=1: player1hit#=0
endif

if bosslvl#=1
   if ballx#<-6.5 and ballx#>-7 and abs(player2pos#-ballz#)<2.25 then balla#=360-balla#
   scale object 2,100,100,150
   player2hit#=1: player1hit#=0
endif

It looks like it should work. The code for the entire game is in the source box. (it's non media so just plug it into DBPro and play)

You got some floats there that have boolean tests on them. Using floats and comparing with '=' operator is gonna lead to problems.
Lose the # from the end of any variable that doesn't need to be a float.
eg:
bosslvl#,player1hit# and player2hit# should be bosslvl,player1hit and player2hit.

Don't know if this is cause of this particular problem but if you continue to use floats and the '=' (for comparison not assignments obviously) you will get problems.

Or instead of if variableabc#=5, use if int(variableabc#)=5.

The word "Gullible" cannot be found in any English Dictionary.

O! I didn't know that affected it. I always thought that the # meant it was a variable. Just like $ is for string.

Edit: Ok, I tested out removing the #s from the end of the variables to make them not be floats, but nothing seems to have changed.

I've decided to define all my variables at the beginning of my program.

So the stupidist question I can ask right now is.... How do you define a boolean variable.

Edit: Nevermind that. Here's the most recent code. The detection of hits still doesn't appear to work.

Well just about defining booleans in DBP I'll go over anyway so other newcomers can figure it out.

A boolean is a true/false variable. By giving it true or false you can check for certain changes such as an object not rotating. In DBP (as far as I know) there are technically no booleans. An integer will work as a boolean you just give it the values 0 and 1 instead of true and false.

Anyway, another newb question. I really should know all of this, I've just forgotton it one way or another.

How do you load an image, texture it on a plain, and then make sure that plain is in the background.

Well, I'm not sure, but what's the point of a boolean? I know what they do, but what's the point?

I ALWAYS have flame proof jacket...just in case...and a shotgun. If you want any, just ask!

We are all nice,except for that one who's name starts in a m and ends in erranvo.

@Programmer of Power
Load image "file directory and name" , imagenumber
make object plain objnum , xsize , ysize
texture object objnum , imagenumber

The position the plain towards the back and make sure it moves with the camera. If your doing a 2d game it's really easy. If your doing a 3d game I suggest using backdrop off , draw sprite to back , then load the image and make a sprite in the backround. That will always appear in the back.

@Evil stick
Think about it this way. How many times when programming in DB have you had to get a value such as upkey(). When you call the upkey the program is checking a boolean if it is pressed or not. If you could not return values in this way then it would be impossible to get any keyboard , mouse , joystick , or internal system data.

I was messing around with all of this, this morning, and I couldn't seem to get it to work either way.

This picture I'm using is currenty only for the menu of the game, but the game itself is 3d.

Since the program is mostly 3d, I tried using the draw sprite to back command, but it didn't seem to work, only the "sprite" part of the command was accepted as a command, so um.... I don't really know how to fix it.

And the 2d version of making a plain and putting it in the back didn't show anything. I made sure that all the cls's were out of the way and such but still nothing.

Why don't you post some code for us to look at?

Um, if you'd read some of the above posts you can see the code, however I'll post the newest code in this post.

In that code one problem that I'm trying to fix is here.

+ Code Snippet

bouncing:
rem BOUNCING
if ballx#>6.5 and ballx#<7 and ABS(player1pos#-ballz#)<1.5
   balla#=360-balla#
   player1hit=1: player2hit=0
endif

if bosslvl=0
   if ballx#<-6.5 and ballx#>-7 and ABS(player2pos#-ballz#)<1.5 then balla#=360-balla#
   player2movespeed#=.5+((.2)*(level#-1))
   player2hit=1: player1hit=0
endif

if bosslvl=1
   if ballx#<-6.5 and ballx#>-7 and abs(player2pos#-ballz#)<2.25 then balla#=360-balla#
   scale object 2,100,100,150
   player2hit=1: player1hit=0
endif

When I run the program, player2hit is always 1 and player1 hit is always 0.

Anyway, back to the image thing. I got the image to come up, but it won't go away, I've tried using hide sprite and hide object but neither have worked, I just get some half-demeted arena with the picture overlaying it.

And the picture only shows when I use the debug feature, just making a compiled version doesn't show the picture.

Is there something that changes between the debugger and the actual program. I press F5 and it loads a game without some of my big fixes for collision and no picture at the menu. When I use the debugger, I have a picture that shows up on the menu but then won't go away with the cls! ugh.
