[Trigger] Fixed flying height - not relative to terrain

[Legal_Ease]

Ok, so maybe this is easy and I'm being dumb again. I made a flight system. It has a lift function which adjusts the units flying height based on a variable. Simply: GUI lift action Events Time - Every 0.03 seconds of game time Conditions Actions Animation - Change Chopper[1] flying height to (Real(Height[1])) at 300.00 However, the chopper flies all crazy going over the mountains or any terrain variation. I want it stabilized. I want the chopper to stay at the same level over all types of terrain. See [VVVV] Choplifter link in my signature if you want to see the whole system. What would be really great is it it crashed into the land if it ran into it or any doodads. Super bonus points for anyone who can point me in that direction!

Hi. Here is something that I think may solve your problem.

CLoc is a location variable that refers to your unit's current loc. The following custom script will give you the value of the terrain's z coordinate.

• Custom script: set udg_Real = GetLocationZ(udg_CLoc)

Then you set the unit's fly height to be relative to the location's z.

• Animation - Change Chopper[1] flying height to (ConstantHeight - Real) at 300.00

If Real > ConstantHeight, that means the chopper is going to crash

For destructables, through a method of your own, we will have a destructable variable an then we use the following custom script

• Custom script: set udg_Real2 = GetDestructableOccluderHeight(udg_Dest)

Same as above, if Real2 > ConstantHeight, the chopper will go all "Mayday! Mayday!"

Oh and btw I am writing these functions free hand so there may be a syntax error or two. Please forgive me if that happens

Don't worry...You type it perfectly

I had encountered the same problem, and I am pretty sure it is in this map. I think I set jumping to F2. Feel free to change the terrain to see if it works.

Ok, I'm doing better now. But the chopper still bounces up and down a little. I was thinking it adjusts itself, so I moved the variables into the same trigger as the animation. That helped a little but it still bounces as it flies. It also seems to be bouncing over doodads (trees). Can't I just set it to a hard Z? What I mean is can't I take the terrain height out of the equation all together?

Ok, I'm a bit of a custom scripting newb. I can fix leaks but thats about it. So... the trigger with Cloc will get the height. Do I create an integer variable called Cloc first?

Ok then, I want the chopper to start on the ground and lift off. So I would "Set Cloc = (whatever the starting height is)" right? Then I replace hieght[1], which is my current variable, with (ConstantHeight - Real)? What are constantheight and real? Are they also integer variables and where did we get them? I also need the chopper to land properly, so a crash would only happen if the chopper's constantheight < real and unit speed > 20. (or something like that). I think you got the solution right, I'm just not quite getting all the details. Thank you x100, for your help. I think you have got me 90% there, but if you could just push me a little further I think we can get it done.

CLoc is a point variable that represents the chopper's current location. You will update it in a periodic trigger.

Constant height is the height that you want the chopper to stay at. Real is the z value of CLoc that I showed you in the custom scripts. Oh and they are both real variables, not integer ones.

I hope this will clear everything out

See edit ^^ oops - never had that happen before.

I had encountered the same problem, and I am pretty sure it is in this map. I think I set jumping to F2. Feel free to change the terrain to see if it works.

Thats pretty sweet, but I couldn't get much out of it for a lift system. Its a really nice key movement system though. It did que me in a bit though. I showed me to use Real variables rather than integer. If you have more I'd love to see 'em.

That's the last full keyboard-controlled map I made... Feel free to do whatever you want with it

Thanks! Its actually a really great system, but its a bit advanced for me. I realize that I need a better movement system - one that permits a side-2-side motion. A chopper game is just not complete without it.

I would love to get some help on it if you are interested, otherwise I'll probably have to dig through your map and try to learn how to do what you did. In any case thank you again, and thank you Doomlord! Both of you have been great!

Glad I helped somewhat
