//******************************************************************************************
// What it does...
// This header file will allow you to create and test a petrol trail which you can then add
// to your mission, with a few useful functions to boot.
// *********************************** Implementation *************************************
/* Add these two lines to the top of your script:
CONST_INT MAX_TRAIL_POINTS 80
USING "gas_trails.sch"
To your main loop add:
CONTROL_GAS_TRAILS(#IF IS_DEBUG_BUILD aWidget #ENDIF) //where aWidget is the parent widget that you use in your script.
This will allow the header file to create a child widget that you can use to edit and create fire trails
To create and test a new fire trail:
1) open up the "gas trails" widget within your mission script's main widget.
2) There are a number of options here:
a) Build -> record route : Pour petrol along the route, as you pour, the route is recorded and can later be exported for script.
b) Build -> view debug lines : Draws the route with debug lines.
c) Test -> reset for pouring : Re-equip your fuel can and then test pouring over the newly created trail.
d) Test -> ignite trail : Demo flames burning along trail
e) Save/Load -> output to script : Exports the recorded trail to script which you'd then copy and paste in to your mission script.
3) Once you've added these lines to your mission, you can add the following commands where appropriate:
RESET_GAS_TRAIL(bool showTrail) : Reset the gas trail for z-skips
FUNC BOOL IS_GAS_TRAIL_COMPLETE() : REturns true if all the points on the trail are removed.
HIDE_GAS_TRAIL() : Make the trail visible/invisible on the HUD.
FUNC BOOL IS_GAS_TRAIL_LINK_MISSING() : Returns true if the player misses a link in the gas trail.
IGNITE_GAS_TRAIL() : Set the trail to burn. It starts burning from the first point that you recorded on the trail.
CLEANUP_GAS_TRAIL() : Tidies it up on mission completion.
Notes: There will still potentially be missing links along the trail if, for example, you pour from opposite directions.
