Legacy GM Detective vision

[ADenton]

Im looking for a tutorial or something guidance on how to go about implementing a batman / arkham night etc 'detective vision' to overlay / change the look of a platformer to highlight strategically important features of the environment. Gunpoint had a very similar sort of thing. From memory that was toggled by the scroll wheel....

Any ideas on resources, leads, tutorials or other guidance on how to implement that?

Cheers

I mean probably want to expirment around with some shaders...

A easy effect I like doing is this to make it a certain color (normally used as an effect for getting damaged)

draw_sprite_ext(sprite_index, image_index, x, y, image_xscale, image_yscale,
rot, image_blend, 0.5);
draw_sprite_ext(sprite_index, image_index, x, y, image_xscale, image_yscale,
rot, c_red, 0.5);

could also probably add an outline to an object by using the scale parametres and image_blend too.

Then of cource some global variable of some kind to tell certain things to be drawn a certain way for the visual effect.

There are a few ways... You can change the surface as the more beautiful way or change the way the object is drawn in general using a variable if(detective_vision)
