How can i make a macro to set an effect at the start of the battle (like trick room, gravity, terrains...)?

Im trying to make a emerald romhack using pokeemerald expansion, and i want to make some battles have gimmicks. Setting weathers is fairly easy because you can just set it on the overworld, but i cant find a way to set other effects.

You can use B_VAR_STARTING_STATUS to enable at least some of those. Looking at the code that implements that variable might help you also enable other things at the start of a battle.

Oh, thank you very much! I´ll give it a try
