I have access to SimPE now so I've been working on some of the tutorials and tweaking some of the custom content I have already.

One such item is Pacotacoplayer's vending machine. I didn't like that it was knocking down the Fun motive (there's nothing seriously unfun about buying from a vending machine unless you lose your money ), plus I wasn't happy with the motive changes caused by the various snack items.

So I started poking into its BHAVs and making edits for my own purpose. I noticed that for the hunger motives and energy motives, he did a straight := instead of += for those motives. I've changed them to += on the relevant lines but what will happen if a sim with 95 hunger eats something that gives a +20 to the hunger motive?

Will the game itself enforce the motive bounds? I honestly have no idea and don't remember seeing this addressed anywhere.

Motives will be clamped to [-100;100]. You will usually see this handled in the script too. If > 64, := 64. But it seems to happen implicitly anyway. Maybe it is needed in an older version. In eating standard food there is no clamping. You add food points and then you add fresh food points to hunger. Look in CT - Dec.
