Effect demonstrated: - RTS Menus
An RTS menu is a menu which, while shown on screen, freezes all gameplay. You press a key from 1 to 9 to indicate your choice.
It opens up possibilities for adding RPG elements to EDGE, since you could use it to have "conversations" with other things, "buy" things in a shop etc.
To use it, we just need to define an RTS script which, when run, will show us our menu.
The actual RTS menu commands syntax is:
MENU_STYLE STYLENAME (this is optional)
SHOW_MENU "TITLE YOU WANT" "FIRST OPTION" "SECOND OPTION"
JUMP_ON MENU LabelToJumpTo1 LabelToJumpTo2
Heres the code with lots of helpful comments :)
//-130 258 is the lower left corner
//and 129 384 is the upper right corner
RECT_TRIGGER -130 258 129 384
TAGGED_INDEPENDENT //Need this or RETRIGGER doesn't work properly
TAGGED_USE //this trigger runs when we press the USE key
TAGGED_REPEATABLE //We can run the script more than once each time we press USE
//Step 1: what we want it to look like
MENU_STYLE MENU3 //I have defined a custom style in styles.ddf called MENU3
//Below I use the "\" character to divide up the command onto various lines
//to make it easier to read but it could all be one line
//Step 2: what we want to show
SHOW_MENU "What Can I do for you?" \
"Health" \
"Ammo" \
"Armour" \
"Nothing"
//Step 3: where we want to jump to in the script in each case
JUMP_ON MENU option1 option2 option3 option4
