WASD Calculation

[fabi202cool]

Hello Guys,

 

maybe a few of the Old Members remeber my release of a WASD-Movement addon for EP1 back in 2012. Now I have seen that there still a few people are interested in this, and my DLL is sometimes randomly crashing the game. So I decided to show you how it works to do it better

 

Basically its very simple:

 

At first I read out the current XYZ Position and very important: the direction of viewing (the rotation of the player).

 

In the next step I calculate the values from the rotation with trigonometric functions, fortunalety our values are in the perfect size for a smooth movement (only 0-4 Steps in the LastChaos Coordination system).

 

At next I add our calculated XY-Values to the current Player Coordinates, we got at Step 1 and write it into the "RunTo-Coordinates", this are the same Values that are set, when you click at some point of the Map. Actually I doesnt remember if you have to set the 1 (Look in the code) to let the client know that the coordinates are changed, that your player is running to these, or if it just stands for the Map-Layer and the Player starts automatically running when the coordinates are changed - you are allowed to find it out

//Prepare Addresses
Base = *(int*)(BaseAddress);
PlayerBase = *(int*)(Base + 0x1C);
PlayerBase = *(int*)(PlayerBase + 0x10);
PlayerBase = *(int*)(PlayerBase + 0x4);

...

if(GetAsyncKeyState(RunKey))
{
//Get Values
rotation = *(float*)(PlayerBase + 0xE84);
cxpos = *(float*)(PlayerBase + 0x54);
cypos = *(float*)(PlayerBase + 0x5C);
czpos = *(float*)(PlayerBase + 0x58);

//Calculate Position
newr = ((float)rotation - 90) * PI / (float)180;
newx = cxpos - cos(newr);
newy = cypos + sin(newr);

//Apply New Position
*(float*)(PlayerBase + 0xE08) = newx;
*(float*)(PlayerBase + 0xE10) = newy;
*(float*)(PlayerBase + 0xE0C) = czpos;
*(int*)(PlayerBase + 0xE44) = 1;
}

I hope you enjoy it

 

PS: Maybe "WASD" is the wrong description for it, because it depends on just one key for running and the arrow keys to rotate, but I hope its ok
