Moving a char w/o ifs, keyup, keydown and global codes..

[poopbrigade]

heres a simple code to make your char move without any ifs. XD

in Draw actor -> Script editor

Code: Select all

char *key=GetKeyState();



y-=(5*key[KEY_w])*((1/(key[KEY_d]+key[KEY_a]+key[KEY_s]+1)));
y+=(5*key[KEY_s])*((1/(key[KEY_d]+key[KEY_a]+key[KEY_w]+1)));
x-=(5*key[KEY_a])*((1/(key[KEY_d]+key[KEY_w]+key[KEY_s]+1)));
x+=(5*key[KEY_d])*((1/(key[KEY_w]+key[KEY_a]+key[KEY_s]+1)));

Code: Select all

char*key=GetKetState();
y+=((5*key[KEY_s])*((1/(key[KEY_d]+key[KEY_a]+key[KEY_w]+1))))-((5*key[KEY_w])*((1/(key[KEY_d]+key[KEY_a]+key[KEY_s]+1))));
x+=((5*key[KEY_d])*((1/(key[KEY_w]+key[KEY_a]+key[KEY_s]+1))))-((5*key[KEY_a])*((1/(key[KEY_d]+key[KEY_w]+key[KEY_s]+1))));

you have y+= and y-=. they both do the "same" thing, but reversed, so it's easy to intergrate it into one single function. since if you add a negative, it's like substration

Thanx learned a new thing XD
do you have anyother tricks in your sleve?

if conditions doesn't limit themselves to "if(condition){}"
here's something interesting when you can jump twice, so you would need to hold numbers of jump in a var.
so to make your actor jump, you could do this:

Code: Select all

yvelocity-=(jump_count>0)*key[KEY_space];

as you can see, no if's is used. But there is a still a condition check in process, so it requires pretty much the same amount of cpu process.

WoW XD I could give you another point but I've used it already.
