[Solved] [Script] Always "thrust away"

[Tormentor667]

I have a question and maybe I simply don't get how things are working.... I have various forcefields in a map. When the player touches it, I want the forcefield to hurt the player and always thrust the player away in the opposite direction, no matter what the forcefield line is facing at. So I made a generic script that looks like this:

Code: Select all

script 400 (void)
{
    Thing_Damage(0, 5, 0);
    ThrustThing(-(GetActorAngle(0)), 32, 0, 0);
    delay(10);
}

What I want to do?

Damage the player, get his angle, reverse it and thrust him away. Unfortunatly it doesnt work so I guess I made something wrong

don't negate the angle to get the opposite direction, add 256 to it. also, the value from getactorangle is a fixed point angle and thrustthing uses a byte angle, you have to convert it. the easiest way is with a bit shift: getactorangle(0)>>8

[MaxED]

Code: Select all

ThrustThing(-(GetActorAngle(0)), 32, 0, 0);

That will thrust player into the forcefield if he backpedals into it...

Would you mind giving me a actual script example for that? I really have no idea how to do what you talk about

Code: Select all

script 400 (void)
{
    int angle = ((GetActorAngle(0) >> 8) + 128) % 256;
    DamageThing(5, 0);
    ThrustThing(angle, 32, 1, 0);
    delay(10);  // Why do you need this?
}

Just to note, as MaxED pointed out, that's still not away. The player angle does not relate to the line at all, so you need to pass the angle from the line.

Yeah, I forgot to mention that it only works properly if the player's angle points towards the thrusting wall perpendicularly.

GetLineAngle(int tag) would be really welcomed here... Is there a slightest chance such a thing would be added if I request for it politely?..

[MaxED]

Well, here's example which works, but requires a bit more setup (you need to pass byte angle of the line to the script).

Code: Select all

script 400 (int byteangle)
{
    Thing_Damage(0, 5, 0);
    if(LineSide() == LINE_BACK) byteangle += 128;
    ThrustThing(byteangle, 8, 0, 0);
    delay(10);
}

Well, here's example which works

Thanks, that works well
