Ok, so first verb complements are a bit complicated, and there isn't really an equivalent in English, so it's hard to translate. As others said, adding 到 essentially means to arrive, or to finish. It's almost like putting the verb into the past tense, but I don't think every verb can use it, so be careful. Now, 得 is much more complicated. First of all, there are 3 different pronunciations for this character. dei3 (meaning to need to) de2 (meaning to get) and then the one after a verb which is just de with a neutral tone. The last one can do multiple different things. First, it can say that the thing following the 得 can happen as a result of the verb that comes before. For example 听懂 means "to hear and understand", 听得懂 means "to hear and be able to understand". The second main use is that it can express a result of the verb. For example 他哭得眼睛都红了。He cried so much that his eyes got red.

得1.like到to express a consequence or degree after verb or adjective.(打得好，长得帅，冷得肚子痛，热得肚子痛。。。。)

lt lsn`t absolute.different verb has different means. except some steady words.到means a thing has a consequence.(跑到公交车上=run onto the bus;得到一件礼物=get a gift)

到 means arrive 得 means get But the meaning depends on the sentence. For example,你得去...means You must to... Wish you can understand,my English is not very good
