Health display on map

[someperson]

I'm not sure if a script exists for this already, especially since this seems minor and would probably just be bunched in with a bunch of other functions in a particular script(that I wouldn't know the name of) so if one does then you can just point me in the right direction. Assuming this doesn't exist, I would assume it would be relatively fast and simple to make. I'm looking for a way to display the player's health on the map in a corner that is updated constantly to reflect the player health. Like if the player is walking and steps on a trap, the player will take damage and the health displayed on screen would reflect that. The health being displayed as "Health: 1643/3295" for example, would be fine since that is what you see when you access the main menu and look at someone in your party. Just trying to keep things simple.

Thanks in advance and happy game making.

It's been done alot before, but it's a really simple script..

I explained most of it in the script, enjoy

Enjoy (and to any scripter who stumbles on this later, if you could tell me a better way of putting the hud on Scene_Map instead of having to edit the original, that'd be great)

-action man

 

[someperson]

Thanks, I really like this. I have two questions. I don't really like the completely opaque window skin it draws in the window. I find it obscure and distracting. Is it possible to change it to be semi transparent like the message boxes use? I also noticed that if I lose health on the map, the numbers don't update unless I access the main menu or go to a new map. Is it possible to reflect changes immediately such as soon as the player loses health it updates instantly to reflect that?

 

[regi]

@action: learn to alias. It's quite simple (much like super, except for any class) and allows one to modify any method with excellent compatibility.

@someperson: For added transparency, add the following above line 17 in the first script:

self.opacity = 150 # customizable, between 0-255

For refreshing, it's a tad more complicated. You'll need to create variables that store old HP, SP, gold, etc. and in an update method, check if the old variable != the actual HP or SP. If so, you would call refresh. Perhaps action can try coding that for you?

 

[someperson]

Yeah that looks much better with the opacity. Thanks.

That concept sounds like I might be able to do it with a common event that runs on paralell process if I use a script command for calling the refresh method in the script. I don't know such command in ruby(well I know zero ruby), but it sounds like it could work. Any ideas?

 

[Kingdom Ablaze]

i know you just got this working, but you were talking about needing updating, mine updates automatically. i have a very basic hud i wrote if you want to use it. here is screen, ignore the top right part, that is another script.

p.s. it uses my color mod script, so there is 255 possible color choices.

edit: also you cant see it, but its designed to have a back ground image if you want

 

[someperson]

I'll give yours a shot as well. Where can I access it? Would I be required to use your color script though since I don't need it?

 

[Kingdom Ablaze]

its only a couple lines of code, i could remove the color script portion. ill upload when i get home

 

[someperson]

Ok cool, thanks.

Edit: I got it to work by messing around with Regi's idea. I just put this under the refresh method in Action's script. To my amazement, it worked.
