To sort of elaborate on what @Havenstone has said,
For targeted scene testing, I use some code I read about somewhere, can’t remember who to credit it to though, so sorry (maybe it was Havenstone!). Essentially, what you do is, have a choice at the beginning of startup.txt that asks if you want to play as normal or in alpha testing mode. Like this:
*title <name of your game>
<your scenes go here>
*create alpha_testing true
<your variables go here>
*comment TESTING CODE STARTS
#Alpha Test Mode
<copy all of your variables here, then *set them as you need them to be for the test>
*goto_scene <whatever scene you want to test>
*comment TESTING CODE ENDS
<normal game code goes here>
So you simply include this block at the beginning of your game, and you can tweak the stats to be whatever you want them to be, then you determine which scene you want to test, and go there. If you need to go to a specific part of a scene, you can just include another label in that file, and say this at the top:
I wouldn’t recommend this unless you’re experienced and understand everything that’s going on. It’s pretty simple once you get it, but it could break your game if you don’t do it right. Also, with that second block, you may need to place it after you’ve created your temp variables for the scene, or it could also cause problems.
Then, when you release the game, you can delete the alpha testing block so that no one accidentally jumps to the last section you were testing.
