well i cant really tell from your picture but the distance seems quite large… if you want something that bounces you up, it’s certainly possible, but expect the second jump to be way shorter (but higher) than the first jump
alot of things allow you to bounce upwards, and i don’t know which is the best… often used are these:
______/ (but have the “/” part slightly more flat, sorry couldnt be arsed to make a picture
)
or even:
_______\ (same as above, slight more flat)
(note that you don’t have to make this out of concrete or anything, it can be “hidden” in a rock… most rocks in supplydepot allow you to bounce on them for example, simply because the faces of the rock are positioned in the right way)
dont make the / and \ bounce thingies too high… about 1/4 player height should be enough.
Also note that players will need quite alot of speed to bounce really high, which cannot be done by a single strafejump… you could make some flat flight of stairs before that hole to give players more speed to do this… (stairs work well as a gamma type of jump without it being too obvious)
but anyway, i dont really like the idea about adding trickjumps to your map… they ruin the fun of trickjumping, which is to find a jump that wasn’t intended to be done. If it was intended to be a trickjump it ruins the fun to do it and also the surprise for the other team, it will be just another route to your objective, but only for experienced trickjumpers…
