I'm getting close to finishing my game, but I want to add upgrades for the weapons. I'm thinking of making upgrades so that you can use combos of weapons (laser + rocket, machinegun + laser, etc.), but I'm not sure how I'll go about doing weapon selection then... There's 3 ways I can think of:
a) have each combination of weapons as a new weapon (hard to find the combo you're looking for, but easiest imho),
b) have keys to switch to each weapon, and if you press 2 or 3 keys at the same time (for example) it would select the combo of those weapons (hard to remember which key selects what weapon...)
c) try making it so you can cycle to a weapon, press a button and cycle to another weapon and it will use those two. (takes a long time to set up your combo)
What do you guys think would be best? (Or if there's a better, way, what is it?)
