The “IF” functions are all used in the same way. Rounddown() – “Always Round Down – aka Floor” Roundup() – “Always Round Up – aka Ceiling” With that in mind, TSM4 adds the following new functions: In TSM4, one of our main goals was to expand on the logic-based functionality of the check() function and make it easier and more intuitive for our users to incorporate logic in their custom prices. If you did not supply a value for “c” and “a” is not is not greater than 0, then the whole thing is treated as invalid. If “a” is greater than 0, the custom price will give you the value of “b” back, otherwise it gives the value for “c”. If “a” is not valid, the custom price returns invalid. The check() function then takes a look at “a”, and looks to see if it is valid and greater than 0.

These 3 values can be any value TSM recognizes, from custom prices to flat gold values, to simple price source references like DBMarket. To quickly explain check(), you can feed it 2 to 3 values in the format of check(a, b, c) where “c” can be optional. I’m pretty sure I used TSM for over a year before I fully understood it! In my own personal experience, check() is definitely something that at times can be hard to wrap your brain around. Many users have become somewhat aware of the check() function in TSM3 thanks to the popularity of BilisOnyxia’s sniper string.
