Step 1: Writing the Storyline

For this example we will create a simple game called Bill's Quest. First of all you need to write the storyline of your game.

Here is the storyline:

D > Welcome to Bills Quest

I > Look

D > You are standing in a meadow, there is a shack on it.

I > walk to shack, open door

D > suddenly you feel overcome by nausea and you fall to the floor in a heap. You drift in and out of consciousness and gradually awake to find yourself in a locked room

I > look

D > You are in a locked room with a table, and a flickering candle

I > Look at table

D > There is a key on the table

I > Get key

D > You take the key that is laying on the table

I > unlock door

D > You unlock the door and walk out of the room

D > You Win

Scr > Shake

That is how I write a storyline. You may do it differently but this version works the best for me. Each of the letters in front of the line represent a different action

• "I >" represents something that the player has to do.
• "D >" represents a dialog or message.
• "Scr >" represents an action on the screen.

 

Step 2: Creating a New Game from the Template

Next create a new game from the template supplied with AGI Studio.

Once you have started up AGI Studio select New > From Template on the file menu. AGI Studio will ask you which directory to make the game in. Click on Create dir... then type in Bills_Quest Then Click the OK Button.

Download the interpreter files and place them in your game's folder.

 

Step 3: Editing the Introduction Screen Code

Now you will edit the code for the introduction screen. At the top of the window labeled Resources you will see a dropdown Listbox this is automatically set to View click the down arrow at the side and select Logic from the list that appears.

Then select LOGIC.001 and Double-Click.

Looking at the logic you should see a line that says:

Code:

<syntaxhighlight lang="agi"> display(10,1," Intro/Opening screen");</syntaxhighlight>

Change this so it reads:

Code:

<syntaxhighlight lang="agi"> display(10,1," Welcome to Bill's Quest");</syntaxhighlight>

Then press the F10 key on your keyboard Then the logic will compile and your game will run.

 

Step 4: Drawing the First Picture

Now you will need to draw a picture for the first room with PicEdit. Download the Priority band .pcx file for this step. once you have unzipped the .pcx file into your PicEdit/AGI Studio directory, make sure that PicEdit is in the same directory as AGI Studio. The Right Click on picedit.exe and edit the program properties so that it looks like this.

Picedit.exe pribands.pcx

Now click on apply.

Once you have closed the properties for PicEdit go back to AGI Studio and click on the PicEdit button

When PicEdit has loaded press F10 and You will see the priority lines.

Now draw your picture using the tools at the bottom of the screen.

This is what your picture should look something like.

After I had added priorities.

Draw the priorities by pressing tab and switching between the two views. For a more full explanation of priorities click here. I do not know where this document came from, I just found it in my PicEdit directory therefore the links will not work.

Make the edges of the water Priority 2.

Save the image as PICTURE.002

Exit PicEdit.
