Picture swap/ behaviour edit

by Anthony Ratcliffe · in Torque Game Builder · 05/26/2008 (11:05 pm) · 34 replies

Ok i have added an avater to my screen called class "image1"what i want to do as when my health decreases i want to change the picture to my avater looking more destressed

this is the code i have editted into the behaviour takes damage, however i am really stumped how to change my image

the names of the image are
image1 - starting image
image 2 - 90 -70% damage
image 3 - 70% - 1%

then in the spawn i want the image to reset, can anyone tell me weather i'm on the right lines and how i go about chnaging the image


if (!isObject(TakesDamageBehavior))

Well if your avatar is a t2dStaticSprite you could use
t2dStaticSprite::setImageMap, or setFrame.

All images you add to TGB in the editor can be found in managedDatablocks.cs or maybe its just managed.cs. Basically each imageMap has its own datablock with a name that you gave it in the editor.

You can assign the image for a staticSprite to use in the editor, or you can do the same thing in script by calling:

t2dStaticSprite::setImageMap( %imageMapObj, %frame );

If it only has one "frame" then just pass 0 or nothing as the second parameter. You use the same function either way.

Ok it looks like you are using one imageMap with multiple frames to represent your avatar's multiple damage states. So when you take damage you want to change the frame but not the imageMap.

I remove some stuff from your onAddToScene method, and I made some changes to the section you marked with "//code edited".

I assumed in this code that your frames look like this...
frame 0 = healthy
frame 1 = distressed
frame 2 = damaged

function TakesDamageBehavior::onAddToScene(%this)
{
%this.startHealth = %this.health;
%this.spawn();
}

//code edited

if (%this.health <90 && this.health >70)
{
   [b]%this.owner.setFrame(1)[/b]
}
else if (%this.health <70 && this.health >1)
{
   [b]%this.owner.setFrame(2);[/b]
}

// code edit finished

Ah i see so if add them to one image and cell split them then set frames ya?

also this is the datablock i'm using

new t2dImageMapDatablock(aaaImageMap) {
imageName = "~/data/images/aaa.png";
imageMode = "CELL";
frameCount = "-1";
filterMode = "SMOOTH";
filterPad = "1";
preferPerf = "1";
cellRowOrder = "1";
cellOffsetX = "0";
cellOffsetY = "0";
cellStrideX = "0";
cellStrideY = "0";
cellCountX = "3";
cellCountY = "-1";
cellWidth = "107";
cellHeight = "98";
preload = "1";
allowUnload = "0";

so in you code %this.owner.setFrame(0)

would become

%this.aaa.setFrame(0)

other wise i cant tell how aaa became owner, because this.owner was already part of the behaviour


thanks ant

No, you should use the code as I typed it.

%this.owner is the object owning the behavior. I assume, that is a t2dStaticSprite.

SetFrame is called on the t2dStaticSprite. If you look in the class reference documentation, you can see that setFrame is a method of t2dStaticSprite and NOT of imageMap.

ImageMap(s) can be used by more than one sprite at the same time, so that is why you wouldn't set the frame there.

This is not the image the behavior will be on, when my main charecter is damaged the picture is changed so i want to change the picture within the health behaviour of the main char

Yes the problem is i dont understand what you wrote, also i've done as you said and its not working,

i'll try to explain i have an animated figure when he is hit by the enemy the picture were changing is the health bar her face changes when hit, so the behaviour is on the animated figure not on the picture were changing, so surley the animated figure would be this.owner not the picture were chnaging which has no behaviour set

Are you saying the image you want to change is a different object than the avatar itself? Like a small mugshot picture of the character like in wolfenstein or doom for example?

You can give that object a name (which you can do in the editor), and then call setFrame on it.

Anthony, I think that you should go over the basic TGB tutorials, as I suspect that you have not. These tutorials explain the sorts of problems that you're facing in detail.

I do a games development course at university on tgb and tge so the basics have been covered.

yes james i think we understand each other now, so basically when my charecter recieves damage the avater changes to diffrent expressions, i'll quickly try that then post results
