Title: Combining 2 scripts?
Post by: Verm on 2005-09-01, 11:07:48 AM

I have to combine two different scripts and I am having an issue where the shooting script loads and the other does not. How should I re enter the values? Here are the scripts btw.

Script #1


Dim nExpectCount
Dim nShot0Count

Title: Combining 2 scripts?
Post by: bluemonkmn on 2005-09-01, 04:23:12 PM

Try this -- hook the shooting script (#1) up to your project and copy the following code into it from the #2 script:

1. Copy this code and paste it below "Dim arBtn1Shots(11)"

Code: [Select]

Dim ScrollerSprite
ScrollerSprite = -1
2. Copy the whole FindScrollerSprite function (beginning with "Function FindScrollerSprite()" and ending with "End Function") and paste it below the code you just pasted above.
3. Copy the contents of the OnAfterMoveSprites handler (beginning with "If ScrollerSprite < 0 Then" and ending with the "End If" right above the "End Sub" -- don't include the End Sub) and paste it in the other OnAfterMoveSprites function, right after "Dim nIdx, VLeft, VTop, VRight, VBottom, VDat"

This worked somewhat, but it created more problems after combining. Now the players Shooting sprites dissapear even before they are off the screen, as soon as the player shoots, the sprites disappear. Any suggestions as to how to fix this ?

This might go faster if you were able to do some debugging of your own; I don't suppose you have any interest in learning a bit of script programming / debugging skills? :)  But I'll do what I can -- I might need your project if this doesn't work out.

First step is to find out what happens if you skip the script that removes the sprites from the screen in order to see if the script is responsible for removing the sprites or if it's the project itself removing the sprites.  In order to do this, add an "Exit Sub" after the code you pasted into Player_OnAfterMoveSprites (right before "If nExpectCount <> ProjectObj.GamePlayer.PlayerSprite.rDef.rLayer.SpriteCount").  If the problem remains, then the script is not responsible for the sprites disappearing, you need to change your sprite definitions in the project.  If the problem goes away, then some more script debugging will be required.  (Although you could probably just delete most of that script and turn on the correct options in the project to delete the sprites when they go off the screen instead.  I think that feature was added to GameDev after the scripting wizard was written, so it didn't used to be an option, but now it is.  Before I tell you exactly how to do that, though, I should find out what the results are.)

I have added that code and it fixed the problem, but now I recieve an Overflow error, It says something about drawing text. What email address should I send this too?

Also  I noticed its while im using my shooting styles this issue occurs, when it goes to affect my inventory.

OK, i have followed the directions to combine the scripts but it's not working for me.  so if anyone can help that would be great.  here's the two that i need to combine for my game.

Dim nExpectCount

This is an autoscroller script.  both work by themseleves but i can't get them to work together.  If anyone can help that would be great.
